The full 8-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Two touch is the default. M41 sets single touch and M42 two touch. M26 selects the part probe and M27 the tool probe.
- Cannot run with cutter compensation, G45 to G48 or ASR buffering.
- If the probe never trips, the end point is stored. Check it before using the value.
- Write a found value to a work offset with G10 L2 P1 X[#5061].
