I have a Blue and White K40 40W laser. I bought the Cohesion 3D board, installed it, and it will not home. The firmware is Smoothie running on a dedicated Windows 10 laptop. USB cable is the one supplied with the C3D board.
From what I can ascertain, when everything is working the gantry should move to the upper left to “home” itself and 0,0 or 200,0 the coordinates and set it up to work. It doesn’t home itself no matter what I try. I turn it on and click home and it moves to the right and that’s it. When I click Origin, it crashes into the gantry and grinds until it stops. I’ve updated the firmware numerous times, changed bed size in firmware and in Lightburn, but nothing works. I’ve put off asking for help until now because I am completely confused.
