OK. That was no help at all. Goose egg on mach3.Even after dumping it drivers and all and reinstalling. In mach 2 ,However,The motors did smooth out at @ 10000 units with everything pegged to the max. Although they were very erratic, still.
Is there an optimum cable length for the motor cables? Could I be losing signal in mach 2 because of overly long cables?
