Need help with firing the torch...Up to the point where we can do touch-off...All works ok...When starting an actual cutting pressing the start arrow, and setting voltage to 118v 45amp and enabling the THC check box, the machine starts it's probing routine, reaches the surface of material, trips the probe switch, comes back up to 0.150" to pierce height. I get message "arc fail"...We performed the test as per PCW directions, with the results that the torch fires properly when shorted pins 3 and 4...We have checked and verified that all wiring is correct. I am at a loss as to why it is not firing.
Any help is appreciated...

HAL file is as follow:

I think you need
# ---Setup spindle at speed signals---

sets spindle-at-speed true

Nothing moves until the spindle is at speed so this fudges it to be at speed all the time

Most probably you have to add Sxxx after M3 in gcode, where xxx is any number except 0.

Rod & Tommylight
The M3 S1 command is already set in the "touch-off" subroutine, so I don't think that is the problem..
I added the sets spindle-at-speed true in the hal and received the following:

./plasma.hal:285: signal 'spindle-at-speed' not found

anything else I should be looking at?
And thanks for your help and quick responses...

Sorry, missed a line, add this too.
net spindle-at-speed           =>  motion.spindle-at-speed

You'll still need the S1 command. I think you can put it in a preamble at the top of your gcode.

Rod,
I left the S1 command as it was in the subroutine...I still get the same error with the spindle signal...

./plasma.hal:284: signal 'spindle-at-speed' not found

Anything else?

I think the sets command needs to come after the other signal. Sorry.

When you press F9 does the torch fire?

I don't see anything in the hal file that connects motion.spindle-on to the 7I76 spindle enable pin
( that's what will close the connection between the ENA+ and ENA- pins on the 7I76 when LinuxCNC tunns the spindle on )
instead you have this:

net spindle-on motion.spindle-on => hm2_5i25.0.7i76.0.0.output-06

Which is fine if you have the 7I76 output 6 driving a relay that connects your torch on signals
but if you are using the spindle enable optocoupler instead of a relay you need to have something like this:

net spindle-on motion.spindle-on => hm2_5i25.0.7i76.0.0.spinena
