Report exactly what is happening.

What is it with you and F9?

WTF does F9 do?

/EDIT AH! I found it....

LOL

Edit after laughing subsided:
It is very useful for testing stuff on plasma cutters and when using run from here.

Turned off arc-ok....still the same
Think i am down to shorting the torch on/off wires to see if it fires, either that or a sledgehammer.
When i pulse fire it, the readout on the GUI shows like its getting volts. The readout goes from 0 to 24 and back to 0 when the cycle ends. If i have the plasma turned off and pulse fire the readout dont change so it seems to be working right.
So i am thinking Linuxcnc and QTPlasmaC is doing what it's supposed to be doing. Just for some reason my torch is not firing remotely.
So what's the safest way to short the wires to see if it fires?

Ok i shorted the wires, still same thing it clicks air comes out but no fire.
So i can eliminate anything control wise right?

I have fixed it!!! It was something stupid, talked to the guy who built the torch. This torch needed at least 65psi coming out the torch head AND post flow of at least 30 seconds.

I think Tom surgested it needs at least 6 bar on the first page.

That has nothing to do with LinuxCNC ...
-check air pressure, must be 5 to 6 bar <<<<<<<<<
-check and change the consumables, tighten them properly
-check the clamp for good contact with material
-check the plasma source for the state, in test mode it will not work remotely.

He kept ignoring most of what we said, so i stopped bothering.
