Macro deactivate thc up and thc down
« on: July 05, 2010, 06:10:17 PM »


I apologize but I do not write very good English, I am using plasma MACH3
and thc 300, I have a problem in circles, when thc does not disable the delay in drilling, is that there is a macro to turn off the thc, but this way there is no delay in the cut, anyone can write a macro to clear the thc-up entries
and thc down?, (and another to activate, of course.
Thanks for the help.

Sorry I don't quite get what you mean by

" when thc does not disable the delay in drilling" All the THC does is move the z up or down based on tip voltage compared to set voltage

When cutting circles turn off the thc, but thc off with no signal detected arc ok,
and I can not implement pierce delay.
The entries disable thc thc up and down, so does the arc ok.

it would also be a script that will disable thc down under acceleration, deceleration and circles, the feedrate is always lower in Cirules that f g code, something like


 if feedrate  < f (gcode) -100 Then disable thc down

That type of operation would have to be done through a plugin to mach.

sounds like you need to use anti-dive.
