Loose or faulty connections can be unpredictable in CNC systems. Make sure your system is properly connected to a power supply. This includes both motors and drives. Be sure there are no faults between the CNC machine and its controller.

Your CNC system should maintain machine zero and part zero indefinitely if working correctly. Loss of positioning is a sign of mechanical or electrical problems. Typically, this can easily be explained by mechanical slippage. Any of the axes can suffer loose clamping bolts, and your mill can rotate or shift front to back in an undesirable manner.

Servo motor failure can be attributed to several factors. If there is no rotation, check for loose connections or foreign matter in the motor. An excessive duty cycle can lead to overheating, or worn bearings. If you are using a DC motor, consider the degree of wear on the brushes.
