ok going to prepare, then move axis, move 1mm, Now if I pick x I move +oo8.0 when I rotate it back to zero I have no movement back. If I do the same thing to z it works moves and moves back. Do I have a bad cable???? Or card.
Well I flipped x for y and it's still in the X not the cables. Got to be a setting in the card or a bad rumba.
Auto home not working the X travils in the direction toward the side that has no switch and I shut it down.
Found the problem! It was me. The End stop Switch was in the wrong place in the rumba it was X max not X min
I found two wire reversed on one of my stepper motor cables, at the RUMBA connector end, black and green reversed, simple fix though.
