M50 (PICK-OFF CHECK)
G00 Z-1. (BACK SPINDLE AWAY)

Example is in inch. Check offsets and clearances first.

Watch out for

A failed check stops the machine before the next part runs into a stuck slug.

Machine builders set many M codes, and they change by model and options. Check the M code list for your machine.
