Hello, I'm having trouble with using M63 (with G1 movement following it) to turn off spindle (plasma torch). I'm using Mach4 hobby licensed.

I have CSMIO IP-M motion controller which unfortunately doesn't let me set the digital output pin to both Spindle FWD AND Output#1 for example.

I would like to use M3 to start since it has all the built-in probing etc. working nicely, but it would be great if I could turn the torch off fast during lead out move with M63 so cuts would be smoother.

I think it's not possible to script M63 to turn off spindle. Any ideas?

Some stock M Codes can be modified and some can not.  For example, I always modify my M30 to do a number of tasks outside of the stock commands; I make sure those OEM commands back into the M30 macro I make.  But the M63 (as far as I know) cannot be modified.  There was a list of m codes that can and cannot be modified and I cannot find them for some reason, I have looked; if I find them I'll post them here.
