Cutter Diameter Compensation
(G40, G41, G42)
Chapter 21
21-54
Error detection M--codes are only functional when cutter compensation is
active. Cutter compensation is active when the control is in G41 or G42
mode and has already made the entry move into compensation. If an
M800 or M801 is programmed in G40 mode or before the entry move into
cutter compensation takes place, the M code is ignored.
If error detection is disabled in cutter compensation, and cutter
compensation is exited (G40 programmed), the next time cutter
compensation is reactivated error detection will be reactivated
automatically. Error detection is always automatically enabled when cutter
compensation is activated.
Refer to documentation prepared by your system installer for the M-codes
used on your specific system.
