4.10.1 G17/G18/G19: Plane Selection
Format:
G17: select XY plane
G18: select ZX plane
G19: select YZ plane
The G17, G18 and G19 commands are used for plane selection. The power-on state is preset to the G17 XY plane. Some G codes (such as round and chamfer of G01, G02/G03, G16, G41/G42 and G68, etc.) only act on the specified plane. Therefore, the G code of the selection plane must be input before those G codes. In addition, the fourth axis has no effect on these G codes at all.
