I've been working on a Tic-Tac-Toe and I'm slowly trying to get it working. I've cleaned the stepper units to the best of my abilities, but I don't want to go adjusting switches and making things worse.
I guess I'm just trying to figure out what area I should be looking at. I have the wire diagram, but from what I can tell the wire colors are wrong and it makes it difficult to track things down.
