Linuxcnc makes some problems sometimes with cuttercompensation, maybe you can make this run.

Thanks.
This not are parametri macro for NTP thread.
Normally will specified more parametric for differet type the NTP.
example fanuc have :
g65 p9063 D50 A10 R5 z-18.55 i-1.84 w0 f250.
This is macro fanuc for continuos threading do initial diameter , angle the conical thread, z finish working ecc.
Existe some example for parametric macro ?
