I would guess it would stop printing and just display an error if it was just the driver. 2. What would cause the driver to go bad? It's the Y axis driver that burnt out. The cable from the driver to the stepper motor is fixed and is perfectly fine. The motor turns fine with no resistance. -- Here's an image of the bad stepper -- https://ibb.co/VmR3zRr
