    DM542A stepper driver

    I just got my cnc kit and hooked them all up for a test run and there is one that has a blinking green light. I switched the motors around and still the same thing.
    any ideas on whats wrong?

    Poorman56,

    Remove the wire connected to the enable.

    With power supply off remove all wires except power wires then power back on and see if led flashes.

    Know this is resurrecting a dead thread but I am having the same issue with a DM542S, blinking green light. Followed the suggestions above but the issue still persists. There is NO documentation out there for a flashing green LED on these drivers. Any help appreciated.
