Chillipepper
While in Chilipepper when jogging 1 axis the other 2 axis twitch.
Slight motion one way when the jog starts and slight motion back when jog stops.
Arduino and stepper driver grounds are all tied together. I had them apart which didn’t matter. Enable pins are all tied together.
I think the enable pin tied together is the problem. Is it something else?
