I was unravelling the wires from around my machine, IH CNC, and put the Y axis encoder wire on the X axis. The X ran away and hasn't worked since. The motor still spins, I swapped the geckos and it's still good, wiring and encoder seem fine. The motor won't even lock up. Powered up I can turn the axis by hand. It will make feeble, itermittant attempts to lock up and the gecko will fault out. I tweeked the gecko adjustments till I can see them with my eyes closed.
Any help is appreciated, Shepard
