Ok. I tried that. I lowered the voltage to 0.4v and even lower. I raised the voltage as well, as high as 1.4v. They still don't want to move. I lowered all the pot to 0.4V to see if the X and Y would work at 0.4v and they still worked fine. I'm just lost here. The crazy thing is that I have two more of these to build. The boards for the other two are different. I think the other two boards are newer than this board. Any other suggestions? Remember, the z steppers have zero load so it can only be a board/ firmware thing. I know the steppers work fine.
