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?
