locate the driver IC on the board MB board for the X motor. There is a small potentiometer right beside the chip and a pad marked TP put a multimeter probe on the tap point
and measure the voltage it should be around 1. 2 to 1.3 . check with the documentation from 3D systems for the voltages just to make sure. This is the current control system for the stepper motors. But it should not of moved. unless you moved it by accident. Remember Stepper motors are always drawing current even when they are not in motion.
The computer locks there windings in place. unless it pulls the disable pin. HI. They run hot but not that hot. much hotter and it could rupture the winding wire insulation causing in internal short. How hot is the chip?
