The local coordinate system is created at the G54 coordinate system (500,500)
position by (3), but the local coordinate system is not created for the G55 coordinate
system.
During the movement for (7), the axis moves to the G54 local coordinate system's
reference point (zero point).
The local coordinate system is canceled by G90G54G52X0Y0;.
