Hold up. How big of a crash. Are things dangling? Is power spewing? Immediately turn off the power at the breaker (by the garage door).

If it was minor (though no crash is minor), continue:


  • CNC:

    • Servos - overload, recycle controller

    • VFD - check for error state. Manually start-stop spindle: M3/M5

    • Verify zero on all axis

    • If spindle stuck on tool changer: remove bolts on the tool holder

  • Tools

    • Integrity: chipped, dull, broken?

    • Collet: is tool held securely, collet loose, tool dropped?

  • Cause of crash - Do not continue until the cause has been identified and rectified. 

Here's the Servo Guide which includes Error Codes.
