Well it’s been a while.
This CNC is an absolute workhorse! I love it!
Everything works and just keeps chugging away, thanks to the amazing support from all the guys and girls on here.
Check out some of the cool stuff we make here.

Well, after 6 years, it’s time to say good bye to this baby. It’s about to leave and move to its new home.
Stay tuned to see my new build that I started last night.
Much the same, just a bit bigger, and faster, and more powerful.
Thanks for all the help and support. I’m probably going to need it for the next one as well.
Cheers

So in its new home now.
Guy has upgraded to 2.9.3.
Now the arc ok only works once per job. So if it’s got 4 cuts, arc ok and thc works on the first cut, but after this it fails out until you select ignore arc ok.
Doesn’t happen on my new machine setup the same.
Heading there now to check it out.
Any ideas?

Does the VAD led remain ON during this?
Always, always disable automation when checking stuff, and enable one by one after fixing things, so auto volts off, void lock off, VAD off, etc.
Only leave THC ON, and do check the Active led while cutting.

Thanks Tommy,
Here now trying to fix it.
First cut is fine. Second cut won’t create an arc ok. Everything off including thc.
Light on the Mesa goes the first time, but second time halshow and hardware all show that arc ok doesn’t change and the input on the Mesa board doesn’t change.

Where is the arc ok derived from? Plasma? Reed switch? or from THCAD?
For first two, check the plasma source, not LinuxCNC/Mesa/THCAD

Thanks Tommy.
Figured it was program as it all worked on the first cut.
Turns out I had to drop the high voltage arc ok from 250 (which is the setting on my machine) to 200. Once this was done it activated arc ok ever time.

I thought you upgraded your machine to a Hypertherm 45XP or similar.
If that is the case, please use the Arc OK output on your plasma cutter as it will save you issues in the future.
You can get the cable (and the interface) for your plasma cutter from QWS in Brisbane
