# LinuxCNC G59.1

Instructions · `G59.1` · verification: source checked

G59.1 selects coordinate system 7 in LinuxCNC. It is one of the G54 through G59.3 coordinate system selection codes. The selected coordinate system stores axis values and an XY rotation angle around the Z axis.

## Study notes

- Coordinate system 7 uses parameters 5341-5349 for X, Y, Z, A, B, C, U, V, and W, and parameter 5350 for the XY rotation angle R.
- It is an error if selecting a coordinate system is used while cutter compensation is on.
- G10 L2 P7 sets offsets for coordinate system 7; G10 L2 does not change the active coordinate system.
