Xr y2 motor stopped

My xr was running great. Then one day the y2 motor decided to quit working. Took ballnut out to get better visibility of the motor. Motor spins real nice and smooth by hand. Could see belt spinning too. But when trying to move gantry only the y1 motor runs. All leads are hooked up correctly. Haven’t had the machine long. Cut some small stuff to start with. With summer here, Haven’t touched machine lately til yesterday. Both y motors were very hot to the touch even with everything turned off.
Any advise would be greatly appreciated.

While I’m not an XR owner, I would think that if you swapped the y1 and y2 connectors at the control, you could help determine if it’s a driver issue or a motor issue.
