G40, G41, G42 are modal codes. Once G41 (or G42) is set, do not set it again
before using G40 to cancel the compensation.
3.20.4 Notes on Tool Radius Compensation
1. When radius compensation is executed, there should be at least one block
containing positioning commands between two neighboring blocks. The
following commands do not perform tool positioning, though they have
mechanical actions. Therefore they are not allowed for continuous blocks .
M05
S2100
G4 X1.000
G1 U0.000
G98
2. Only G00 and G01 are applicable to blocks with tool-tip radius
compensation. Arc commands G02, G03 are not allowed
3. The tool radius compensation function is not available for MDI operation.
