Good evening I am currently in the middle of a diy laser build and having some issues with the stepper motors. I am not sure if they are just not powerful enough or if it is my controller. I am running nema 17s with a Cohison 3d board. The x will move a bit, but very choppy, the y just sits and hums. I have tried liner rail and now v wheels, both are doing the same thing. They are very and will roll from on side to another, I am just not sure of the problem.
