Hi
This is a new setup, Sanyo Denki stepper motors, Kinco 2M2280N high voltage drivers with a PMDX 126
bob.I have a big problem with it. I cant run mach3 with it because I have 30 to 70 ACV on the stepper motor casings. Tested the stepper motors, there are no leaks. Dont know what to do, cheacked the wiring its ok. Thinking about changing the drives? or the lot
Thanks for any help

David
