Here is a short video as an example. Not sure what happened at the beginning, but the last few seconds show what is happening. This was only using the x and y jogging on an xbox 360 controller. I don't have a star ground on the case, however I've attached the shield wire from all 3 stepper motors to a bare nut and machine screw going through the case wall. I wasn't running debounce, But I've went up to 2000 and increments, and it didn't help the issue. It is happening randomly, I can run for awhile and not have the interference, then all of a sudden it starts up
