I also get the following when I start my configuration

This is telling you that you haven't yet saved this parameter (you don't even need it unles you have Powermax comms), you can stop it by opening the run panel and pressing Save

Sorry, I read that wrong...

Traceback (most recent call last):
File "./plasmac_gcode.py", line 55, in <module>

This shouldn't happen, there is a bug in my error checking, I will fix this. It is possible that this is causing some issues because normally when you get an error like this the program doesn't completely load.

I totally misread your error message and went off on the wrong tack.

For some reason Gmoccapy is trying to load "imperial_squares.ngc", you need to edit "az_cnc_plasma.pref" so:just reads:You cannot open files on program load with PlasmaC as all the required HAL pins are not yet established.

The next thing you need to change is Arc OK Low, a starting point for that is around half of your expected cut volts. You can tune it later if you wish.

That is why the ARCOK is going on and off all the time, it should be set at something like 60 to 80V.

my current arc ok low is set to 0 would that not be achieve the same as of half of the expected cut volts as you suggested?

It will behave like Tom said. The slightest bit of noise would give an Arc OK then if the noise disappears then you will get a lost arc.

Well 50:1 seems closer than 75:1. Is it possible to measure the arc voltage with a meter while you observe the arc voltage on the Axis GUI.
