Thc wont shut off or turn on when using m666 and m667

Alrite guys and gals I’m running mach3, sheetcam, and a proma 150 thc… Using the mach 3 with probe and scriber post processor i Can’t get my thc to shut off for holes using the m667 and m666 rules in sheetcam and I don’t see a script file written or how to write a mach3 script to shut it off and turn back on … Anyone know what the deal is? Thanks!!!

You simply put the following lines in the macro file.

In M667.m1s
StartTHC()

and in m666.M1S
EndTHC()
