The full 9-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Q must be positive. A missing Q gives an error or a single plunge depending on version.
- Use G73 when chips only need breaking, not clearing.
- Cancel with G80 on its own line. A left over cycle drills at the next XY move.
