Yes, the THC is working correctly.
When i disable the THC then the movement form the Z Axis does not work, even if a thc controller request is pending.
Everthing OK.

OK, thanks.
I think we have to pick one of two options.

1. Hide the THC Active Led when in mode 2.

2. Turn on THC Active when THC is enabled and Arc OK is sensed. This is note quite true as it doesn't take into account any delay from the Arc OK signal until THC begins working. I assume these external THC units do have a delay.

IRC, Proma had a 100mS delay for sampling the voltage and a short delay for the time it takes the relay to switch over.

Thanks Tom, a short delay like that kinda makes option 2 look not too bad.

You are welcomed, always.
Am in a hectic state getting the big machine ready for transport and wiring a 120A plasma source to it with THCAD and everything, it has to be ready for tomorrow.

Yeah, it always seems to be a rush at the end. Good luck.

I pushed the changes for the mode 2 THC Active Led
