G91 INCREMENTAL POSITIONING
N_ G91
The G91 command defaults the system to accept all coordinates as incremental, or relative, coordinates. This command is found at the beginning of some programs to default the system to incremental coordinates. It is possible to switch between incremental and absolute coordinates at any time within a program (see the G90 command).
