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!

I am not an expert, but what you are dealing with is totally fixable. It will take a little bit to sort through it.

Those splices are kind of ugly- how comfortable are you with soldering and the like?

How are you at reading schematics?

Connector J6 looks like a power distribution block for 5V & 24V power. Its on page 2.

The rest of the layout is fairly well documented so that you can transpose the old board to Ray’s board.

That would be the 6 pin connector older boards used… The last picture in the install guide at cohesion3d.com - Getting Started shows it…

And also you can search this group for “moshi” - that’s the old board that had these connectors.
