Torch will not Fire

Have a looked at that pin with halmeter or halshow to see if it switches on when it should.

It switches to true when i pulse the torch and air comes out now, just no fire.
The on/off wires i have one connected on hm2_7i96.0.ssr.00.out-00 and the other right next to it at ssr.00.out-01 is this right?

I had the two wires switched and the torch fired when i turned on the plasma, pretty sure that means i had reverse polarity?

Switched them and now air comes out when i fire the torch but no fire.

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.

It should be TB3 13 and 14 which are OUT0- and OUT0+

It's connected to TB3 13 and 14 if you include the "in common" in the count. Its connected to the first two after it. As i said earlier i can switch the wires on the same two pins and the torch fires when i turn the plasma on, so i know the torch head works.
Odd thing is my arc ok light comes on for a brief second but no arc. The torch on light also comes on.
It sounds like i can hear it switching on and off, just never fires, but that might just be the air i am hearing turn on & off.
I have plenty of clean air, pretty clean metal and good ground directly to the metal to be cut.
I dont think my plasma has a test mode or anything.
Only thing i see maybe odd is my voltage offset, it seems high to me but maybe not. It's 100000 not sure that would affect the firing of the torch or not anyways.
Edit: I fixed the voltage offset issue. It now shows 24v when i pulse fire but no fire come out.

What are your settings for Start Fail Timer, Max Starts, and Retry Delay in the parameters tab?

Do you get any error messages when it fails?

Do you have a Torch Pulse button as a user button?, if so does that work?

If you are using Mode 0 then it could affect it depending on the Ok High Volts setting.
