With my 45xp set in marking/gouging mode and turned down to 10 amp as the book says, 50mS torch on time set in PlasmaC, I still have the same issue - the first torch fire works, the second does not, the third one does. I don't have the mechanized marking shield they call for but the other consumables are as called out in the manual.

Next test is Phill's experimental version posted earlier.

With the plasmac.comp Phill posted earlier:
With torch on time set to 77 (cut volts is 78 and use auto volts is disabled) - the torch never fires. Air flows and the Torch On button briefly lights.
With torch time set to 299 - torch fires every other time (same problem)
With torch time set to 450 - torch fires every other time (same poblem).

I'll try to call Hypertherm next week to see what they recommend.

That seems odd, what does the Arc Voltage display?

I think it stayed at 0. I even turned out the lights and there was no flash from the torch on that test.

I am not sure at what voltage your Arc OK comes on at.

At values lower than your Arc OK if the torch doesn't fire then the Torch On light should stay lit and it should be waiting for the correct voltage or Arc OK, whichever comes first.

Did you rebuild after copying the file across?

Well, I got in a hurry and missed the instruction to rebuild. I just swapped the file and restarted LinuxCNC. I will rebuild tomorrow and try again. There are no other changes in the file other than those relating to dimpling? I’ve got some parts I need to cut tomorrow and wanted to be sure this file will be safe to use.
