Common failure points for this unit include the main PCB’s power supply board, the stepper motor driver outputs, and the serial communication interface to the host computer. Check that the unit receives proper 24 VDC from its power supply, verify all I/O connectors for continuity and correct pin‑out, and review any error codes displayed on the DRO screen or logged by the host software.
