Plasma floating head...

How so? You call your modified M3 and it does it's G31 to set Z zero - then what? - you then have to cater for the float switch offset - then move to pierce height THEN fire the torch - where are you intending on firing the torch if not in - erm - M3?

No sorry we are at crossed purposes I was meaning using G31 etc with it's own Macro which would get called before Pierce height etc and not in the M3 macro. This I thought would mean Float switch could be done away with.?
To be honest I've never messed with Plasma so didn't exactly know how the torch was fired but did suspect M3 would play apart.
