Thank you. Forgive me for asking, and please understand that this is a real question, but how could it be the USB cable? It stays connected as long as the steppers and wire grounds are disconnected or the spindle is removed from the motor mount... in both scenarios it stays connected with every USB cable I have tried.Originally Posted by machinehop5
