The full 6-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- The rapid back down stops above the last peck by the Peck Clearance Distance on the Holes Parameters screen.
- Basic NC uses up to three positive Z words: total depth, first peck and later pecks.
- Q is modal and is shared with G76 and G87 shift. Reset it.
