Just as the title says i can't get my mill to move. I have a C10 BOB, KL-4030 Drivers. I think I've pretty much narrowed it down to Mach 3. Voltage going to everywhere its suppose to, the only problem i found is when i try to jog a axis the COM or negatives on the BOB has no ground. PLEASE HELP!!! This is day 4 of rewiring and head scratching.
