Centroid Community CNC Support Forum

When I power on any of my 4 servos (DMM DYN4 1.8KW) the 101keyboard stops functioning. The on-screen keys continue to work. I am referring to the Centroid touchscreen workstation.
Any ideas, I am commissioning so the only thing grounded is the 120vac power supply. The dyn4 drives are grounded, but not to electrical panel yet.

Is the 101 keyboard wireless or USB? If wireless, I suspect noise from the drives.

No it's USB, when I cycle off drive breaker, sometimes the keyboard comes alive, other times I need to unplug, and reinsert into USB. I am going to try running a temporary ground wire across the floor to ground point on main breaker panel.

Grounding drives took care of issue. Thanks Tom
