    I wonder if the stepper driver for the X axis is turned up too high, there's a pot to adjust the current to the driver on the board inside the metal box. When you're trying to only move the X it overloads the motor but when you use X&Y together the power supply can't supply enough current to over load the X.

    If there is a pot you must be very careful when you adjust it if you use a metal screwdriver otherwise you can short something out but it's really very easy and nothing to be scared of.

    Check this vid out for 3d printers but the principles are the same just bigger motors as you have an all in 1 board with built in steppers.
