Addresses
| Address | What it does |
|---|---|
X Y | Move to adjust, usually incremental |
D | Offset number |
How it works
One shot, group 00.
Example program
G90 G54 G00 X0. Y0. (START POINT)
G91 G45 X2. D08 (MOVE 2. PLUS THE OFFSET)
G90 (ABSOLUTE)
G91 G45 X2. D08 (MOVE 2. PLUS THE OFFSET)
G90 (ABSOLUTE)
Example is in inch. Check offsets and clearances first.
Watch out for
- Old style function. Cutter radius compensation G41 and G42 is the normal way today.
- One shot only. The offset applies to the move in the same block.
- Do not mix with G41 or G42.
