I have just installed the C3D laser board in my K40 laser
I have just installed the C3D laser board in my K40 laser. Installation went without a hitch and everything seemed to work well until I started doing some serious projects. I found that the Y axis is well out of calibration. All vertical dimensions are about 15% too large. Is there some way I can calibrate the axis in the software or is there a setting that I am not aware of? Any help would be greatly appreciated.

Installed the C3D LaserBoard. It was easy
Installed the C3D LaserBoard. It was easy. The only snag (literally) was the cord for the end stops needed to be tugged a bit to actually reach the spot on the C3D board. Now with LightBurn and C3D I can directly control it from my Mac rather than the strange combination of a Windows PC with K40Whisper, Drop Box and Team viewer I was using and hour ago. The one question I have is all of the other boards have pin out diagrams (Mini/Remix) but no diagram for the Full Sized board. Any ETA or am I missing a link somewhere (along with the screw that is loose)?

Question for the group. My laser was more powerful at 100% before I switched to the cohesions 3d
Question for the group. My laser was more powerful at 100% before I switched to the cohesions 3d. I have heard that there is a potentiometer, but I only see one on the stepper driver, not on the board itself. This website says to set the potentiometer to 10ma and then test different power levels. 1. Where is the potentiometer? 2. How do I connect to it with my multimeter to ensure I’m not over charging my laser? 3. Are there additional settings in the config file that would adjust the max output?

Hi all, new c3d mini/lightburn User here, running GRBL LBC

I have an older version of the K40 laser
I have an older version of the K40 laser. It has a parallel computer connection rather than a USB socket. I figured that the C3D laser board would get rid of the parallel connection as well. Problem is: the power socket is a 6-pin socket that does not fit the 4-pin socket on the C3D board. I can measure the voltages coming in on the socket but I am not sure how they are connected on the board. I was wondering if any of the screw connectors on the board can be used for the incoming power rather than the socket and, if so, exactly what the connections are. Thanks in advance.

Have HM Rotary installed on the A Port of the Cohesion Mini board
Have HM Rotary installed on the A Port of the Cohesion Mini board. Issued G0 A10 nothing happens. Have installed on the micro card firmware for 4 axes and a config.txt for the same additional axes. I tried unsuccessfully to see if Lightburn would display the axes it sees like XYZA. Issued M114 in console of Lightburn and it shows only XYZ, no A . The Rotary has been proven good. Does the M114 report the A port if active? Do I need a heat sink plugged into the Cohesion board A port?

Greets, good night !!!! I thank the members of this interesting community who can help me
Greets, good night !!!! I thank the members of this interesting community who can help me. I have a k40 co2 machine with a Moshidraw V4.1 card. She worked perfectly for a month until without any reason the X-Y axes stopped moving. When I turn on the machine it should be positioned at point 0,0 but it does not move. Likewise when you start the computer, the axes should move to the position started in the software. When I send a file to print the software indicates that the machine is busy. The connection is well made because the devices in the control panel appear well configured. What could be the failure ???

I got my replacement C3D mini board in for my K40 and finally got my dedicated power supply I ordered last week for it and plugged everything in. One thing seems like it’s not working still: the Z axis only moves in one direction no matter what direction I select. The Z table was tested and working fine when plugged into the X and Y axis and jogged so the hardware on that end works fine. I have narrowed this down to either a board or config issue, but I’m not sure what to do further. I saw this post: https://plus.google.com/109943375272933711160/posts/CwYLrztb5Ky

Hi, Can someone tell me how I can reset my c3d mini?
Hi, Can someone tell me how I can reset my c3d mini? Reset isn’t working and power up doesn’t seem to work either. I’m trying to use GRBL or if I could reset, I’d use Smoothie. Anything that might actually work would be good. Last time I tried this, I tried several different, good quality mini SD cards and none made any difference. I’ve been trying to diagnose problems with running my laser but am starting to think that the problem might be with the control board itself. It is prbably user error, but I have exhausted all the possible fixes that I am aware of. At the minute I can’t use it at all. I have the firmware .bin on the card but it doesn’t reset to firmware. CUR and the control is completely erratic. Thanks.

I am having issues with my C3D board connection to the computer
I am having issues with my C3D board connection to the computer. Randomly it loses connection to the computer and resets the laser to the home position. This happens at random times and can occur in the middle of scanning, cutting or when the laser is idle. I have run diagnostics on the computer and shutdown all non-essential services but the issue still is present. I get the sound of USB device connection and then the laser moves to home when it happens. Any ideas???

So I hooked my C3D board and downloaded the files on an SD card and made my first engraving!
So I hooked my C3D board and downloaded the files on an SD card and made my first engraving! It came out ok, I need to get familiar with the speed and power settings for the wood I’m using. However when I tried another piece I came into an issue. First off, Lightburn doesn’t recognize the k40 on the “auto” setting of devices. No big deal, so I hit the drop down menu and the only port is gives me is COM3 but my k40 is actually plugged into COM4. So I unplugged the USB and plugged it back in and it eventually gave me COM4 as an option and as soon as I hit COM4 I could here the K40 connect. I jogged the machine to the spot I wanted to start and it jogged just fine so I know it talking. When I hit “start” for the machine to start engraving the head moved to the starting point and froze there, the laser never turned on. Lightburn thinks the engraver is going I assume because it says busy under “laser” and the timer starts to increase. However the bar never gets fuller and the percentage at the end of the bar stays at 0%. At those point the software seems frozen, I hit the “stop” button but can no longer jog the laser. The only way to get coms with the laser again is to disconnect and shut everything down and try again. When I do try again everything works fine up until the point I hit “start” then everything freezes after the laser moves into its initial position. Yes the laser works when I hit the laser test switch.

New to the K40 community! have been doing a lot of work with my my eleksmaker A3 and wanted to step up to something more powerful but not spend 5k. So glad I stumbled on this community, I love the idea of spending ALOT less but having to do some upgrades/work on your own part to get what you want. All that being said I’ve received my C3D bored and read all the articles for setting up. I ordered the bundle that also came with the power upgrade. It looks like I was suppose to get an SD card? I did not see one in the package, so I need one sent from cohesion or can I just format one and download whatever software onto them myself.

I bought a Chinese Red/Black x700 clone and I want to upgrade the controller and display. Do you have a controller and display that will work on the machine? If Yes, what is the cost and what do I need to do to install it? Ideally, I’d like to have the Remix model and display.

I finally got my K40 laser in and installed the Cohesion3D board and it looks like I'm only getting the solid red LED and none of the green ones
I finally got my K40 laser in and installed the Cohesion3D board and it looks like I’m only getting the solid red LED and none of the green ones. It is connected to USB, I’ve tried several cables and known working USB ports and it doesn’t look like it’s going to start up. Does it look like everything is hooked up right? Is there something else I need to be doing here?

So I have a very weird issue
So I have a very weird issue. I have been running external stepper drivers on all axis for a few weeks now on my cohesion3d mini. All was good, I started having one driver that was loosing steps so I decided to upgrade all 3 of my driver to better ones. Now I have this almost double image during engraving. Nothing else was changed, shut the machine down, set the new driver settings and swapped them out.

Problem. The machine correctly performs the contours of the picture, but only when the laser is off
Problem. The machine correctly performs the contours of the picture, but only when the laser is off. When the laser is turned on, the machine is stopping, in LihgtBurn the task time is running, but the board is not available (status in software - disconnected). Is it possible than I use an external power supply 12V / 5Amp (24 volts from PSU is not connected, ground of laser PSU and power supply are linked) or because of the memory card (2GB)? Are there any memory card requirements?

I have some issues with my 12864 smart lcd that im curious if you guys have any ideas or solutions. The lcd displays fine until i press down to get to the menus or turn the encoder then the screen will either display gibberish or go blank and stay blank. If I restart itll work again until i touch the encoder. The lcd will still beep as feedback when i push down on encoder when screen is blank. Its a cohesion board with smoothieware on a k40 laser.

Thank you to anyone that helps me
Thank you to anyone that helps me. I am setting up my rotary and I need a little help with the settings. I have read the manual and did my on research before I posted my call for help. I have a cohesion3D smoothie board and a DIY rotary from Thingiverse attached to A-axis. I have attached photos of my Lightburn rotary settings and a photo of my rotary. In LB I drew a 10mm x 10mm box and started the job. The laser makes a 10mm line with the X-axis however the A-axis rotates a lot more than 10mm. So I end up with a long rectangle. I think I need to update the config.txt file for delta_steps_per_mm but I am not sure what is the correct number. The delta_steps_per_mm is currently set to 100.

So I am all installed and up and running, however I'm having some issues
So I am all installed and up and running, however I’m having some issues. The 1st and most important is that my scans look terrible. Choppy edges and awful resolution. I’m 99.99% certain it’s not mechanical as I have run over 4k jobs on this k40 and it was my highest resolution laser b4 the board switch. I have tried adjusting the potentiometers with no success. I have adjusted line interval, overscan, and reverse interval for hours w no success. The laser makes a lot of noise while moving now that it didn’t b4, like the steppers are struggling or something. Even cutting vector lines are wavy. There is zero play in the head & no loose mirrors or lens. Help!

Hello everyone, I received my Cohesion3d Mini board today and promptly installed it in my K40
Hello everyone, I received my Cohesion3d Mini board today and promptly installed it in my K40. I have an extensive electronics background and there was nothing difficult here. I did read the installation notes before installing and they mentioned the PCB should be mounted in a way that isolates it from the chassis ground. I 3d printed a bracket and installed it. I was able to use it all day today while I was getting a feel for the Lightburn software. I wasn’t having any trouble. Then towards the end of the day, just before I went to start a job smoke spewed out of the board and I immediately cut power.

Hello all, I have had a Cohesion3D mini board for about a month now and everything has been working great until last night when I started having a problem where, when running a job, some of the cut lines were way off alignment. I tried reinstalling Lightburn and the first job ran ok but the second one did it again… does anyone have any idea what’s going on here? Although it looks like I have moved the material during the job, I can assure you this is not the case. Here are some photos comparing a properly aligned job with one where it’s gone out of alignment.

I purchased a C3D mini a few months ago, and I just got around to installing it today
I purchased a C3D mini a few months ago, and I just got around to installing it today. It ran for a bit, and then stopped working. I investigated, and I’m now getting just the single red led light for vmot when power is applied; none of the other leds are lighting up or blinking as they were when I installed it this morning. I’ve verified that the stepper motor wiring and all the other connections are sound and correct; I’ve also verified that the separate power supply I’m using is putting out a solid 24v. Any ideas what might be wrong?

I have the C3D mini.... and coming back from a break the K40 laser will no longer fire when running a job from LaserWeb 3 when before I left everything worked fine
I have the C3D mini…. and coming back from a break the K40 laser will no longer fire when running a job from LaserWeb 3 when before I left everything worked fine. LW3 seems to have kept the same working config (but I need to double check this agains the info on the C3D site) so I don’t think it is that. I checked all the wiring, fume extraction, water cooling and so on and cant find anything wrong. The laser does work as when I push the ‘test’ button the laser fires. I therefore suspect something linked either to the C3D mini board (lost config / firmware?) or the windows laserweb software. I have yet to look into this correctly but does anyone have any idea as to what the issue might be?

I see the C3D Mini has a 5V input pin
I see the C3D Mini has a 5V input pin. Is there a way to disable the onboard 24V->5V regulator and use the K40 power supply’s 5V output to power the C3D, and is there value in doing so? (I thought it might be better to reduce the load on the K40’s 24V output so it can just power the steppers)

When I command the laser to move using Lightburn the X-axis moves twice as far as it should
When I command the laser to move using Lightburn the X-axis moves twice as far as it should. When I was using K40whisper I was able to change it’s settings for X scale factor to 0.5 and then it moved 10 when I sent the command to move 10. How can I do this with Lightburn. I’m think this might occur because I had to replace the X-axis motor when I first purchased the K40 and it may not move T the sale rate.

I am interested in installing a Cohesion 3d board in my old K40 but I am concerned that my laser may be tool old (about 2014) Here is a pic of my main board
I am interested in installing a Cohesion 3d board in my old K40 but I am concerned that my laser may be tool old (about 2014) Here is a pic of my main board. My laser also has the large green power resistor on the side wall and some reading on here led me to believe that may present a problem. Can anyone tell just by looking if I will have any luck replacing this board with the cohesion? I dont want to order one if it also means that I need to buy a new laser at the same time. Thanks in advance for any help!!!

Hello! I received my C3D K40 bundle today and after some close inspection I noticed the heat sinks supplied with the stepper driver modules cone in contact with SMD components on the modules
Hello! I received my C3D K40 bundle today and after some close inspection I noticed the heat sinks supplied with the stepper driver modules cone in contact with SMD components on the modules. The adhesive also allows the heat sink to move in top of the driver chip. This seems like a poor design as a possible short could result in damage to the module and or board, they can easily slide and come in contact with the header solder joints. I may put a chamfer on the edges of the heat sinks to add some clearance from the SMD components. I have similar heat sinks on my Ras Pi boards and the adhesive is very firm and does not slide when mounted. This is more of a heads up on a possible issue with the shipped heat sinks.

Greetings all. Just installed C3D and so far so good
Greetings all. Just installed C3D and so far so good. Just 1 question so far. Laser is a K40, 1 year old, had to replace the power pot. Comp. system is Windows 7 ultimate. Nano board was working fine but I wanted the flexibility of C3D. My question is that it seems that I still have to control laser power by the pot. When I try to adjust it through Lightburn I get maybe 20 % difference in the overall performance. I’m a little puzzled?

I am about to install a new C3D mini board in my K40 laser cutter, powering it with a separate 24V PSU unit from that of the K40. The C3D will then power and control the motors and the endstops via external PSU, however it must still be connected to the K40 PSU for controlling the laser. I traced and checked all the connections involved and this (see pictures) seems to me the correct configuration. I’d appreciate your comments and/or warnings before I proceed with this operation. Thank you!

Hi im from switzerland so sorry if my english is not the best
Hi i‘m from switzerland so sorry if my english is not the best. My setup is a windows 10 gamer laptop and lightburn software. I installed it and everything was working fine. At first i run smoothie but changed it to grbl because i‘m more used to it from my other laser. After some testing and calibrating everything was fine and the first test cut with a small rectangle i was ready to go and happy but after a while it lost connection. It was not running any jobs or something i only had lightburn open and connected with the machine and suddenly lost it. now i cant connect to the board and the sd card is unusable. I tried to upload the firmare again, both the original and grbl but it doesnt read the new or the old card. The new one was formated correctly to Fat32 but there wasnt even a change in the smoothie file. The green leds dont blink for even a second. Just the VMOT and 3V3 are blinking in sync with the power supply. The old m2 nano board works fine without a problem. Thanks in advance for every help!

Hello, I recently got my C3D mini board up and running on my K40 machine
Hello, I recently got my C3D mini board up and running on my K40 machine. At first, I was only able to control the X axis. I was not able to move the Y axis by hand and could not get lightburn to move the Y at all. I did some reading on here and found the configuration files that +Ray Kholodovsky uploaded to remap the Y axis to the A axis. With those files and the Y axis hooked up to A, the machine works well and I am able to control both axes.

So I've spent about 12 hours today getting my Cohesion 3D upgrade into my K40
So I’ve spent about 12 hours today getting my Cohesion 3D upgrade into my K40. It homes fine and runs fine until the laser fires. Once it fires LightBurn disconnects and everything stops. This also happens when I test fire the laser. So after reading all of the posts here I installed a second 24Vdc Power Supply. I ran 24V and Gnd into the screw terminals on the C3D board and disconnected the 24V from the stock PSU. Still exact same same result.

Hi guys, I’m having some issues with my cohesion board (using lightburn). When I try to cut a svg file the hearts look like in the picture.

Complete newbie here, and Im hoping yall can help me out
Complete newbie here, and Im hoping yall can help me out. I bought a laser second hand, and bought a cohesion3d to put in (assuming it was stock). Well, the old owner had a board from chriscircuits (to run Mach3) and I am clueless as to what he did and how to make it adapt to the new cohesion board. I know nothing about hooking up connections, but it looks like he spliced wires together, and the 4-pin connector that needs to go to the cohesion board has too many holes and doesnt fit, plus it looks like he skipped a hole. Please help!

Hello - I am working on a homemade rotary axis for my K40 (with C3D mini)
Hello - I am working on a homemade rotary axis for my K40 (with C3D mini). I have installed the 4-axis firmware from the directions on the website and have gotten it to move using Lightburn. But I don’t see any A-axis position information on the LCD nor can I find a way to jog the axis from the LCD. By chance is there a newer version of the firmware that supports the A-axis from the LCD interface? The main reason I am asking is that I am having a hard time figuring out how to correctly position the A-axis to start the engraving at the desired location on the rotating material (an A readout position would be helpful in figuring this out). Thanks!

hey there. All good with my installation and the engraver is all working
hey there. All good with my installation and the engraver is all working. However, and you knew there was going to be something, the software just stops part way through the gcode. The first time it was just 5% off finishing so I lived with that, but the past three times it has not even got to 50% of the way through. Is this a memory thing? I have attached a couple of screenshots to see if that helps. As you can see there has been no movement since 15:39 minutes to 17:53, in fact there has been nothing since 9 minutes.

Attached is photo of my stock k40 board as it was delivered
Attached is photo of my stock k40 board as it was delivered. It works with the stock software. Notice the yellow wire is not the outer wire on one of the plugs. I have installed the mini. When the k40 homes the gantry starts in the correct direction. If it hits the Y home switch first it stalls (chatters) there. If it hits the X home switch first it stalls (chatters) there. I have tried reversing the X plug with the red lead inboard as shown in the installation video without success. I’m using LightBurn software. Any suggestions?

Just got the c3d installed and have the motors running
Just got the c3d installed and have the motors running. I have not tried the end stops yet and I have to get it to find home (it just jogs it around or grinds back center of machine). When I check position it says machine is sitting at 0x and 210y and if I move head to bottom of machine it says it is at 420y but I can try to figure these out latter. The power is working and it runs cuts and image, so I am happy so far but looks like a LOT more playing to get it honed in. Thanks to every one who helped get me this far.

Exciting new problem! I started a print from octoprint on my cohesion3d mini board
Exciting new problem! I started a print from octoprint on my cohesion3d mini board. It had done countless prints before now with no trouble. Suddenly serial lost connection. after a bit of digging into how to try to connect octoprint to printer over usb, I try a dmesg on the pi to find it putting out “unable to enumerate USB device” messages. Seems like the USB chip(?) on cohesion3d mini might be kaput. Any guidance?

I'm trying to get a 3Dmini setup on a CR10 using BLTouch
I’m trying to get a 3Dmini setup on a CR10 using BLTouch. When I run G30 to check the probe Z offset, I get expected results. However when running G32 to probe multiple points, the Z jumps up to Z18 and tries to probe in mid air. This is exactly opposite of what should happen. I don’t think the initial Z is getting saved properly. Running G92Z0 with the nozzle on the bed shows Z is zero by way of M114. I also save with M500 and M665. To reset the BLTouch I need to raise the nozzle off the bed to extend the pin and start the G32 probing. I have no idea why G32 would send the Z so far off in the wrong direction. Z configs are here: https://hastebin.com/xiqahuleka.coffeescript

I have it installed and it too is working. I can figure out most of the menu options but there are some that I am not sure what the do? I thought I’d ask if there is any instruction about the menu option before I just jump right in and start experimenting and maybe frying something. Any help would be greatly appreciated.

howdy gang, so I’m a bit at a loss right now. Got my c3d-mini hooked up, got first moves and the end stops working from what I’ve done so far.

I verified the wires are not broken. Could it be a bad board?

Have some questions concerning my new mini
Have some questions concerning my new mini. It has never beeped at all, but otherwise seems to be working since it goes through the light sequence, plus I can engrave and cut using LightBurn. Is there a setting for this feature or could the beeper be defective? Also having some issues with power levels. I tested it by manually setting it to 10ma, then set it to 3/4 power using the controller, but it pretty much stayed at 10, and when I put it at half, it goes to like 3/4 etc. At low power, it was doing 5ma, so not sure what’s going on there. The tube also squeals a lot now when energized below 15ma. My steppers make noise when idle, but I guess that’s fairly common and nothing to worry about unless they get hot. Using the stock supply, so could this be part of the problem? I also need to do fast raster, so I guess I have to switch to grbl? Thanks for any info you can give. :)

I went to test for my laser and it seems that everytime I that fire the laser or run a job the LCD buzzer goes off and the cohesion 3d board disconnects
I went to test for my laser and it seems that everytime I that fire the laser or run a job the LCD buzzer goes off and the cohesion 3d board disconnects. I have tried running it through the computer and LCD does not make a difference. I don’t know if the LCD buzzer should be going off, but I know that it shouldn’t be disconnecting. In addition if you had the test fire button to long or to many times the machine will go into it’s boot sequence with the buzzer on and will stay there so the buzzer will just be going off with werid text on the LCD or the laser firmware info. I have my wiring configuration below. I am using new motors and no endstops so I do not need the ribbon cable from the stock k40.

Hi there, I'm a happy user of K40 and Cohesion3D mini update, however I still can't really get my head around the laser homing parameters in the config.txt file
Hi there, I’m a happy user of K40 and Cohesion3D mini update, however I still can’t really get my head around the laser homing parameters in the config.txt file. I have a lot more bed space than the one I seem to be allowed to use with the combination C3D and LightBurn. My home coords are set now at left rear position but there’s a lot more space on the Y axis (in fact a couple of mm also on the X) to set it further down. However the homing goes always a little up than what I wish, so possibly the 0,0 can be reset in the config file, or am I wrong?

My laser - soon to be upgraded with C3D board (I hope)
My laser - soon to be upgraded with C3D board (I hope). I got my board a few days ago, but have not had time to work with installing it. As you may be able to tell, my laser is in a closet, and needs to be pulled out in order to get at the side with the electronics (under the big exhaust vent pipe). I have been working on bettering the exhaust fan system and seem to have it worked out now. I use the fan that came with the machine on the inside, and designed a window box that uses 2 X 140mm Noctua industrial fans (look like PC fans but run at 24V and move a lot more air). The only problem that I have now is that I need to leave the door of the laser open about 2” to let air into the machine to exhaust the smoke. Anyway, you can see my new panel inside the laser - cut from some left over 1/8” hard board. Hopefully the install of the new C3D board goes smoothly this weekend.

On my K40 I have a very noisy air assist and its a real pain to have on when not needed
On my K40 I have a very noisy air assist and its a real pain to have on when not needed. I have been going through all the details of how LightBurn works and noticed that on the cut/scan/image page there is an option to enable air assist. Looking at the generated G-Code they are using M106 and M107 (fan on off). I also noticed that they are not using the S option to set the pwm value. So my question is can I go into the config.txt file and change switch.fan.output_type from PWM to digital and not mess anything up? I have an SSR for switching 120V that I could use to turn the air pump on and off. I am already using one on my 3D printer with a 120V bed heater which draws way more power the the air pump.

Hello I have a Cohesion3d mini and a K40 laser
Hello I have a Cohesion3d mini and a K40 laser. My PSU is a bit different than the ones I have seen here and on the website. I got everything to work except the PWM for the laser. I think the laser wire from the power supply is supposed to connect to the center conductor of the K40 PWM connector above the servo connector. Is that true? When I connected it up the laser is always on. Any thoughts? Do I need to do something different with the firmware?

I have a K40 with Cohesion3D Mini board I just installed per the instructions on your site, it was working fine for about 2 cuts then i turned off the laser came back and it was no longer responding to commands
I have a K40 with Cohesion3D Mini board I just installed per the instructions on your site, it was working fine for about 2 cuts then i turned off the laser came back and it was no longer responding to commands. I could still connect to the board, and when i hit a control key in laserweb 4 to move the x/y axis nothing happened. After some trouble shooting I pulled the micro SD card and tried to load it on my computer(linux) it appeared to only be 512mb(not the 2gb it’s marked as) after trying many things I can not read the SD card and can only assume that it’s failed/corrupted. I had another micro SD card, formatted it to fat32 put on the firmware/config.txt files from your site tossed it back on the C3D and boom it’s working again like before. Is SD card failure a regular thing? Is there anything I can do to avoid this? If this happened in a few months I wouldn’t sweat it, but at this point the C3D board has been on for under 1hr total.

I just bought my 2nd C3D Mini but this time for a 3d printer Im building
I just bought my 2nd C3D Mini but this time for a 3d printer I’m building. Before installing anything on it, I’m trying to see if my RepRap LCD works. My PSU is 24v and using default config.txt. When I tried with my LCD connected, it just whines without turning on. Tried it with no LCD and VM0T stays red with the other green leds flashing. Do I need to put the steppers to try and test the board? My first one for K40 it just works so not sure if Im doing something wrong.

I bought a K40 upgraded version (digital readout)last week everything works just fine out of the box including homing and limit switches
I bought a K40 upgraded version (digital readout)last week everything works just fine out of the box including homing and limit switches. The limit switch connector, 4 wire power supply molex and stepper motors are the only wires in my setup. I installed the C3D with laserweb4. Machine Jogs and laser burns files. The only issue is does not home on startup and limits do not stop the gantry on x or y. I did inspect for pulled wires in the limit plug it looks ok. The connector only fits one way in the c3d for the limit plug connector, but I tried the plug in reverse in the off chance the connector was soldered on the board backwards no change . Is there a software setting that needs to be configured? Thanks Cherryman

Hey guys, i installed the coh.3d mini into my k40 and when i start the machine the glcd whistles and quits
Hey guys, i installed the coh.3d mini into my k40 and when i start the machine the glcd whistles and quits. The machine doesnt home itself when i start it. When i click on jog on the screen the laser head moves but it never homes itself. Is this board not homing itself like the m2 nano board? Also the dial knob on the lcd when i turn it left it goes down the list when turning right it goes up. The same when joging. Is there a way to reverse it? I believe it should be the other way round no?

I have the ribbon cable variant k40 laser, using c3d board
I have the ribbon cable variant k40 laser, using c3d board. I have an issue with one of the end stops for homing, I have two optical end stops. I am going to try to fix the optical end stop but if that fails as a backup I will try to switch to mechanical end stops as suggested on k40 board. I had some questions, if I were to switch to mechanical end stops, would you ditch the ribbon cable or can I keep it plugged in for the x stepper power supply and then run separate wiring for my mechanical end stops? I think the power supply for the X axis stepper comes from the ribbon cable currently, it then has a connection to the stepper through the little board that has the Y axis optical endstop; if I had to ditch the ribbon cable the stepper motor can be unplugged, then I would run connections from the stepper motor to the 1B1A2A2B above the X A4988 driver board, and run my x and y end stop wiring to the bottom of the board x and y end stops as done for the z table end stop.? If the ribbon cable can be left in place that would be one less thing to have to change.

Anyone have issues with their laser studdering when it gets to a spot it needs to not engrave?
Anyone have issues with their laser studdering when it gets to a spot it needs to not engrave? Its almost like it doesn’t know what to do. Smooth until it hits a white spot stops for a millisecond goes over it and starts to engrave again, even though I have Laserweb to “Burn white” it seems to stop to turn the last off and then back on again. I think this may be part of my issue with the picture shifting.

Ray Kholodovsky been a while since I have done anything with your board
+Ray Kholodovsky been a while since I have done anything with your board. Trying to get it working. It connects fine, I can see the firmware and config files. Changed a few settings in the config file to set limits and such. This is for a 3d printer. Connected to it with pronterface. It will let me heat the hotend but that is all. None of the movement commands move the steppers. I am powering with 12v. Should I switch to 24v? I doubt that will fix my problem. I am fairly sure I have the wiring done correctly. Not sure how to set the pots on the drivers correctly. The way I did it on my old printrbot was send a move command and dial them till I got a good smooth movement. I assume you can turn off the smoothieboard default config for current settings because the driver boards use pots. The only other thing I can think of that could be wrong is maybe the motor wiring. I wired them the same way as my printrbot which I thought should work. It is setup phase 1 then phase 2 but the a and b pins might be out of order. I saw some people talking about measuring the vref to set the pots correctly, how do you do that? These are 1.3a motors. Hmm just thought of another way I could set my pots I have a simple movement board I could tune each one on that then move them back to the ReMix board. I can send you the config file if that will be helpful. I don’t think I broke it, but who knows, it is 3am here.

I’ve reformatted the SD card and added the config and .bin files again. But each time I open Laserweb and connect to the machine, it reads a grbl connection. Do I need to change something else?

It's a minor thing and maybe nothing can be done about it
It’s a minor thing and maybe nothing can be done about it. I’m using the grbl firmwared Cohesive3D mini and LaserWeb. The issue is that at the edges of anything I’m Lasering (more noticeable for engravings of course) it’s always a little darker like it’s lingering at the edges or something, the speed seems to not effect it much. Is there any settings that can help this in the firmware or LaserWeb? I know it might be just how it is but I figured wouldn’t hurt to ask.

Still having problems with my skipping I was dealing with a couple months ago, I decided to change the firmware to grbl last night and seems to not be happening anymore. Only problem is my laser has no adjustment in power. The directions say to connect to mosfet 2.5, in smoothie my PWM wire is 2.4! i unplugged it and moved to 2.5 and nothing. Just all laser all the time. Anyone who has gone it care to shed some light on how they got their wiring hooked up?

Now that I have my Cohesion3D mini I have noticed a problem when I am engraving grayscale images
Now that I have my Cohesion3D mini I have noticed a problem when I am engraving grayscale images. It’s like my images are shifting or skipping on the X axis part way through. As far as I can tell it’s not physically the air assist catching etc and on the stock board I was running faster and via the USB without kipping issues. The images I am engraving are at 300mm/s and on the stock I was running 500mm/s no issues, though that was black and white images. To eliminate the USB connection, I put the job on the SD card and that helped but I am still getting it some. Suggestions?

I have a question about PWM,. I have seen the instructions and it seems that "400" in "laser_module_pwm_period" does better then "200" for me but it still seems it goes so quickly from light to dark and watching the ma meter
I have a question about PWM,. I have seen the instructions and it seems that “400” in “laser_module_pwm_period” does better then “200” for me but it still seems it goes so quickly from light to dark and watching the ma meter it goes max the last 3ma of a 10 grayscale range test the first which is at what 10% of the seems to read at maybe 4ma so it start high. Test grayscales, I can get maybe 2 good shades of light, but once it goes even medium dark, it goes way dark, I am guessing because it caps out I know it’s not exact but I think further tweeks could maybe get me closer. What does “laser_module_pwm_period” exactly do so I can try and determine if I need to go down or up from “400”? Basically right now when running the PWM test code from the website the amperage starts high and ends high so it’s capping out fast at the top end. I know I can make further tweaks in LaserWeb by setting the range and it has helped. I do have it kind of going, and it’s neat and I know there are limitations but I think I can do a little bit better based on what others have done.

Well, it took a few nights over a couple weeks but my K40 is successfully upgraded. All the bits and pieces I’ve purchased over the last year are installed and working with the C3D just fine. Mechanical home switches are now where they should be. Z-table and thus air-assist head all installed. PWM looks to be working as it should.

Is there a way to make it travel from top to bottom without it jumping around to different areas to burn I think this would really help the constancy of the mark? I would assume this is the board processing the image? See photo for example. It jumped around from top to side at least four or five times.

Hey all, decided to upgrade my smoothie firmware this weekend, so I downloaded the new config.txt from support and smoothie cnc firmware. After flashing it made my LCD garbled and laser fire continuously, So i went back to my saved copy (from when I first got my board in the first shipment batch). Everything worked again. Forgive me since I haven’t really checked the forums since I got and installed the board back then, since it’s been working all these months.

More connection issues. I finally gave up on Smoothie working right, I went the grbl that was in the Cohesion3D website dropbox. I deleted the firmware files, I left the config file on there and copied the grbl firmware over. I rebooted, and seems it installed because I can’t see the minisd card in windows anymore. Now I can’t seem to get LaserWeb to see the board at all. The lights on the motherboard are different, the top is green solid and the bottom is solid red (top being the direction of the USB port).

I’ve tried changing laser_module_pwm_period which curiously was initially set at 20 not 200 in config.txt to 200, 400 and 600. After reset it still fired at 100% as you can see. What should I look at next?

I made this diagram for a k40 upgrade customer
I made this diagram for a k40 upgrade customer. On the not-well-known HT-Master board (it’s the red one, but not Moshi, apparently this is what comes in the new “upgraded” K40D now), the endstops are on a 5 pin JST, but unlike the M2NANO where there is a X wire, Y Wire, and common Ground (2 wires crimped to 1 pin), here there are 2 separate ground wires with the 2nd one on what I believe to be the lowest pin. Since this is not connected on the Cohesion3D Mini, and since not everyone may want to recrimp that entire set of endstop connections, a quicker workaround may be to pop out that wire and move it to a ground connection on the Mini, such as the Ground pin of the 5v Aux header, all the way at the bottom left. Just wrap the pin in electrical tape or something first, because we don’t want it to short 5v to Gnd.

So, lots of problems! The below backwards pepsi logo is a) backwards and b) supposed to be red logo 5% power, blue bit of logo 10% power and writing 25% power. C) endstops don’t appear to be working. I have connected screw 4th from left to L +Ray Kholodovsky suggested. I’ve wired the 24v +/- in the correct places. It cuts, but the power setting is only working through the POT. Any suggestions? I live 155 miles away from the laser and get 2-3 hours a night for 2-3 nights a week and this is the hackspaces only laser. If there’s any magic suggestions I’d very much appreciate it, it was a lot of money to drop on this board specifically for plug and play rastering!

Maybe seeing something wrong in my Laserweb settings or the gcode. Really grasping at straws now and not sure where to turn to.

I am trying to set up the lightobject z table
I am trying to set up the lightobject z table. I have the light object 24V power supply and zlm3020 2A external stepper driver. I saw the diagram on the cohesion3d documentation for wiring it up with cohesion3d, I followed that and have had some problems. I am using the glcd to try to jog the z axis. Stepper moves but not smoothly and only in one direction no matter which I direction I try to jog z axis; x and y axes jog normally. The external stepper driver is switches are set to supply 2A. The micro steps switches are set for 1600. I am using the 5V off the cohesion3d board for the 5V with the PUL+, ENA+, DIR+ all jumpered together with the 5V supply. I confirmed the pairs of leads to the steppers hooked up to A+A- have continuity and the leads with B+/B- have continuity. The power supply is working and putting out 24V.

Success (the middle engrave, don't mind that I've sent this test over other failed engraves)!
Success (the middle engrave, don’t mind that I’ve sent this test over other failed engraves)! Previously I was having issues with my C3D Mini shifting on files and locking up when running from the SD card. A new board later I was no longer locking up, but I was still having a shift in detailed raster engravings. The new board did something other than what the old board did, after it shifted right, it eventually corrected itself. Which I thought was weird.

Hi Ray, I have some problems with my upgrade
Hi Ray, I have some problems with my upgrade. After I add a Bitmap or vector image to LW4, the rastering is only but a black area as big and wide as the boundary of the design. I have shared images with Ariel Yahni on the CNCpro g+ and so waiting for some more suggestions from him.

I've got the C3D board in and wired up as shown in the instructions
I’ve got the C3D board in and wired up as shown in the instructions. My K40 has a ribbon cable that drives the stepper motors. I plugged the red, blue, yellow, white plug into the X access on the board. Problem, I don’t get any movement on the X access. I get nothing if I switch to the Y access. the led lights are doing what they should. I put the original board back in and I get both X and Y movement. Any suggestions?

So i’ve installed the cohesion 3d. I’m getting the red light (obviously from the picture) and the remaining five green lights. 2 and 3 are flashing as per guide.

But when i try to manually jog the controls or home it, it does nothing. Under “live jogging” disabled is marked. Does this need to be enabled? I tried clicking on it and it wont change.

Hey guys, I can't seem to adjust the speed for engravings
Hey guys, I can’t seem to adjust the speed for engravings. I have no experience with laser web 3 or 4. When I jog the axis they move at a speed that I am able to change, but I don’t see where I could adjust the speed while engraving. It seems to move at a good speed when it’s on a white spot, but when the laser is on it moves extremely slow (roughly 0.1mm per second). The S% (I assume speed) is set to 100% while it’s running. Any help is appreciated, thanks.

Having issues running a larger job and hoping someone can give me some paths to start investigating, when running the file from the computer/USB cable, around the end of the job I get a shifting on my X axis that is random
Having issues running a larger job and hoping someone can give me some paths to start investigating, when running the file from the computer/USB cable, around the end of the job I get a shifting on my X axis that is random (see two instances in the same cut attached) but always finishes the job. When I run the same file from the SD card, it locks up the Cohesion3D Mini tight and in two cuts, both the same spot each time. Have to kill power, even a reset won’t free the board.

Hello everyone, I got my Cohesion board a few days ago, and I can't get it to work
Hello everyone, I got my Cohesion board a few days ago, and I can’t get it to work. I’ve gotten the board to connect to both LW3 and LW4, but the motors wont move. I have the ribbon cable connected to the board that goes to the Y axis, and the X axis 4 wire cable connected to the driver that came with the board. I have turned up/down the pots because I didn’t have any other ideas, and still nothing. I am up for troubleshooting, but I don’t know enough about this board and engraver to do it on my own. I am lead to believe it’s something between the board and the motors, because I can connect and talk to the board with LW4, it just won’t jog the motors. Any help is appreciated, this could just be a noob problem.

If I manually move the laser head with the laser powered down and the USB lead unplugged it seems to be powering up the Cohesion3D board somehow
If I manually move the laser head with the laser powered down and the USB lead unplugged it seems to be powering up the Cohesion3D board somehow. I only discovered this because the screen starts to beep. I’m guessing that the motors that usually move the laser head are acting instead as generators and passing power back to the Cohesion3D board but that doesn’t sound to healthy.

Hi there! Just installed my Cohesion3d Mini upgrade package on my ribbon cable / digital display K40, followed the updated directions to a T, everything boots up and connects to Laserweb 4 properly, and when I run G28.2 It homes in the Y Axis properly, but then disregards the X Endstop and keeps crashing into the Left end of the X Axis (where it should home. I know the end stop is good, as I just used it minutes before installing the new board, but do you have any ideas +Ray Kholodovsky? Let me know if there are any specific settings/ photos that might help diagnose this.

Hello everyone, I recently got stationed at Holloman Air Force Base and my laser engraver finally showed up yesterday from shipping
Hello everyone, I recently got stationed at Holloman Air Force Base and my laser engraver finally showed up yesterday from shipping. The tube didn’t get broken in my move which I am very happy about. I have been looking to upgrade my controller for awhile, and decided I would do it when I got here. I saw the great things that Ray and the community have been doing here and the Cohesion3D board looks nice, and thought about getting one myself. The biggest problem is I’m not confident if my PSU and wiring is compatible with a Cohesion3D. I was looking at getting the “Cohesion3D Mini Laser Upgrade Bundle” with the GLCD to replace this crappy chinese software and controller, and also add a PWM ability. If someone could point me in the right direction and tell me what I’m doing right or wrong, I would really appreciate it.

Got my external psu wired in, but it's still skipping on pictures
Got my external psu wired in, but it’s still skipping on pictures. It’s almost like it’s being over loaded and misses a few steps and does the rest of the picture. Small stuff under 50-60mm is fine, over that it does it. To me sounds like a memory buffering problem maybe? Via USB ran straight from laser web and also downloading the gcode to the SD card does it

I have the cohesion mini 3d board replacing the m2 nano
I have the cohesion mini 3d board replacing the m2 nano. the wiring conversion was minimal just the 12 line ribbon for the x axis motor and x & y endstops, the 4 position power connector 24v G 5v L, and the y axis connector. that all i did other than the discount display board. control via the rosary switch works fine, except test firing the laser. manually firing works. installed lw4 works great but no laser action.

Hi Ray, Just a quick note that I don't think the yellow 'PayPal Checkout' button works correctly
Hi Ray, Just a quick note that I don’t think the yellow ‘PayPal Checkout’ button works correctly. I used this to try and place an order. It took me directly to PayPal who took payment from my PayPal account and then sent me back to your single page checkout where I started to register but your site wouldn’t accept the order and dropped me back into the basket page. Oddly enough PayPal then refunded me saying that they thought it was a fraudulent transaction. I’m trying to create another order right now but going through your basket, hopefully that will work. (It looks like you use a hosted version of bigcommerce, it might be worth speaking with them about it)

I just picked up a new "upgraded" red K40 and a Cohesion3D board
I just picked up a new “upgraded” red K40 and a Cohesion3D board. I’m looking at setting the stepper driver current and was wondering what these are usually set to? From the M2 board, it looks like it’s set to 0.6A and 0.4A on the X and Y. I saw no markings on the steppers themselves. I’ll be running a dedicated power supply, so overall current doesn’t matter. I’m building a motorized table, so I’ll need more power anyway.

Can someone point me in the right direction as to what settings will affect edges of engravings being burnt more than the center of engravings?
Can someone point me in the right direction as to what settings will affect edges of engravings being burnt more than the center of engravings? I have read that the smoothie firmware will adjust power level based on how fast the laser head is moving. It doesn’t seem to be very effective for my engravings. All of the engravings in the image are Laser Fill Path in LaserWeb4. Also you can see the drastic difference in color between the split M and the actual M. The M along with the split lines are all one vector outline with Laser Fill Path to engrave it. Settings I used are pot at 10mA and LW4 at 40% for the fill path operation. Thanks for any help!!

I'm trying to install a LightObjects motorized bed in my K40
I’m trying to install a LightObjects motorized bed in my K40. I’m pretty sure I’ve got the stepper wired up properly, but I can’t get motion out of the motors. I’m checking my assumptions before digging deeper: in regards to the smoothie config that ships with the C3d Mini K40 upgrade kit, does it ship with z-axis enabled to the point where jogging the z-axis from the LCD should produce motion of the z-axis stepper, or is there more config required in the smoothie settings (beyond setting proper steps/mm?) This is my first foray into Smoothie, I’m much more familiar with Marlin.

I use an HP Proliant DL 380 server as a workstation*( One aspect of servers is they are designed to boot from anything, USB port, floppy, CD, LAN, and of course any drive or array).

Anyway just to say that it is so easy to do, if anyone is thinking about it, just do it, you won’t believe the difference it makes.

Thanks in advanced!

Ok, this is turning out to be a nightmare
Ok, this is turning out to be a nightmare. Either Laserweb is not going to work with this board or this board is not going to work with laserweb. All I do is chase one issue after another. I cant engrave with power lower than 10% unless I drop to 150mm/s or lower, if I dont the laser may or may not fire. 10% is to high of power to engrave lower than 300mm/s and even at that speed its an absolute rough mess. So if I lower the power I have to lower the speed, which has the same outcome as a the higher speed and 10%. I cant change the beam width to anything lower than .13 or it comes out with jagged jumps to the left and right or the laser hardly fires. I have already changed the the wire over to L and the whole 9 yards. Changes in setting that are made that should not effect the laser firing does. Changes to speed, power that should not effect the laser firing or the outcome of the paths does.

Installed C3D mini into red/white K40. All going well so far
Installed C3D mini into red/white K40. All going well so far. Including pics of my before and after connections for others, of course YMMV. Note that the stepper motors needed to be wired up with the white wire towards the middle on both connections, exactly the same as on the M2 Nano board. This puts the configuration as bottom left is 0,0 in cartesian coordinates when using LaserWeb3/4. Using Y endstop as MAX rather than min to define the Y axis.

Nubbi Question - I looked at the install guide and all the screen shots but I don’t see a standard as to which direction the stepper motor connectors for the 3d mini are supposed to go. On some pics I see the white wire on the left and on other pictures I see the white wire on the right.

I installed the Cohesion 3D Mini in my laser and it is working
I installed the Cohesion 3D Mini in my laser and it is working. It was a pretty standard installation using the 3 wire PWM cable(power supply has the white connectors). What I am having a problem with is that I have to set the minimum laser power to 75 to 80% when burning a calibration file for it to even mark in the 0 to 50% range. I have 2 K40’s This particular laser has always required a higher setting to do the same thing as the other laser. I have voltmeters on both lasers. This laser would take 1.6 volts to produce 4 to 5 milliamps where the other one only requires .5 volt to produce 4 to 5 milliamps. I have had a Smoothieboard(one of Scott’s ACR kits) in this laser before and it worked.Comparing the Configurations files I don’t see any great differences in the laser power settings. Do you have any ideas of something that I can try to get this dialed in?

Just a little progress on the CNC
Just a little progress on the CNC. I’m working on adapting one of the older style C3D mini boards to replace the TinyG that I’m currently using on my CNC. However since my Shapeoko uses dual Y motors and I’m planning to run a rotary, I had to adapt the Y-axis socket to run two drivers since there weren’t enough driver sockets on the board. Normally without the rotary you could just take over the A output and configure it accordingly but I can’t let things be that simple can I :)

Hey all! I only have weekends to play with this, my board install was easy as could be, with help I got laserweb up and running. I’m not savy at all with software so I’m learning that. I’ve got a problem I could use help with please (as I only have the weekends)

Just wanted to share what the production glcd adapter will look like installed in the c3d board
Just wanted to share what the production glcd adapter will look like installed in the c3d board. I had access to test the only pre production version. It feels right, and definitely finishes the look.

Ray Kholodovsky on the mini headers for the drivers, is there a preferred A1, A2, B1, B2 for the stepper pinout?
+Ray Kholodovsky on the mini headers for the drivers, is there a preferred A1, A2, B1, B2 for the stepper pinout? I’m trying to hook up my rotary in place of the Y-axis just to test and it didn’t seem to like that that order. It just stuttered.

Does anyone here uses all the 6 stepper slots and would be so kind to share his config-file with me?
Does anyone here uses all the 6 stepper slots and would be so kind to share his config-file with me? I tinkered two days now, and am only able to get 2 Extruders up and running. But not 3.

I can confirm that YES, you want to move your M3 and M5 commands into the G-Code start and end sections of LaserWeb if you're using the mini 3d
I can confirm that YES, you want to move your M3 and M5 commands into the G-Code start and end sections of LaserWeb if you’re using the mini 3d. I’ve gained almost all of my speed and smoothness back that I was missing previously.

Hi Everyone, so I am in the process of acquiring my very own K40 and first thing I do after making sure it works is to replace the board
Hi Everyone, so I am in the process of acquiring my very own K40 and first thing I do after making sure it works is to replace the board. I was originally going to order a smoothieboard but I came across this great looking cohesion3d board that looks to make the install process easier!

Ray, after installing the SD card it looked like it worked fine BUT, the y axis only goes one way, maybe not getting the dir signal
Ray, after installing the SD card it looked like it worked fine BUT, the y axis only goes one way, maybe not getting the dir signal. Tested X on smoothie and works on both motors then tested y on both and it only moves one direction, then moved driver to z and both work fine using z. It is ONLY the Y axis that will ONLY move one direction. It cannot be the connectors because they work fine and it can’t be the driver chip because it works when moved to the z axis.

Update #1 on the boards. All 100 ReMix have been visually inspected at this point
Update #1 on the boards. All 100 ReMix have been visually inspected at this point. We are currently working through testing each one manually. First few have been good. We flash the firmware from the MicroSD Card and then do a full functional test to see that all the motors spin, endstops trigger, thermistors read, and mosfets can run heaters. As well as the GLCD and all other fun stuff.

Hello all I recently installed the C3D mini board into my newer-ish k40 available off of e-bay
Hello all I recently installed the C3D mini board into my newer-ish k40 available off of e-bay. Most of it went smoothly, if no one wants to read the link I will post below, note that the laser will fire if the gantry is moved while the board is off, but machine powered on. Not sure why, so be careful. Otherwise the install went great and +Ray Kholodovsky was very helpful along the way, great man he is. I have some pictures in my little install guide and will post some here as well as I finished my new face plate to hold the glcd and a amp meter (however I got the wrong one, new one will be in tomorrow) so never mind it is not the right one, haha… If anyone wants the file for the control panel will upload. here is a link to my install guide, though it is a very rough draft I will likely go in and fix some things and add more details. https://docs.google.com/document/d/1f4u79SzF7th84rFIfUXIpY8u4YEpwoGeH7z-K8yjxQc/edit?usp=sharing
