Hi! So, on my Bot, I can move the y- axis away from home, but cannot convince it to return to home, or move backwards at all. It moves smoothly away from home, but does not even attempt to move back. There was not sound, jittering, or anything- the motor just does not do anything. The X-axis moves back and forth smoothly, servo-motor works; only the Y- axis is experiencing this trouble. I would appreciate any feed back you guys have, and thanks.
