How it works
Modal, polar group. Default at start up.
Example program
G0 G20 G90 G54 G17 G40 G49 G80 (SAFE START, INCH)
G0 X0 Y0 (CENTER)
G16 (POLAR ON)
G0 X1.0 Y45.0 (RADIUS 1 AT 45 DEG)
…
G0 X0 Y0 (CENTER)
G16 (POLAR ON)
G0 X1.0 Y45.0 (RADIUS 1 AT 45 DEG)
…
The full 6-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Put G15 in the safe start line if any program uses G16. A left over G16 turns X and Y into radius and angle.
