Description of Issue

Traction belts not moving when head is cracked down on board. Or when testing the x-axis, you will be able to hear the x motor running but the belts are not moving or knocking.

Possible Causes

Cause can be: that the x drive gear plate assembly is stripped, on older machines that still have the 2 piece plate, it may be that the plate is separating, either the large or small gear is missing teeth not allowing the metal gear to move them, or the small metal gear that the x motor moves is broken or stripped.
