D | Offset number |
How it works
One shot, group 00.
Example program
G90 G54 G00 X0. Y0. (START POINT)
G91 G47 X2. D08 (MOVE 2. PLUS TWICE THE OFFSET)
G90 (ABSOLUTE)
G91 G47 X2. D08 (MOVE 2. PLUS TWICE 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.
