USB disconnect on "disable motors"

Post by arhi » Tue May 02, 2017 1:35 am

Not sure why but "almost" every time (19 times out of 20) after the motors are given command to go offline (the stepper driver EN pin disabled) the USB connection is lost. Is this some bad EMI on the board or some other reason (like enable driving something else on board, I see that motor driver EN is linked also to relay to switch off temperature measurements and some other stuff too)
