Hy
hopefully someone can tell me what are the AUX 1 and 2 are for?
Nothing at this point in time. They are not used for THC.
Aux 1 is a configurable 24v output that is currently not enabled in software ( it is there for Future features) do not connect anything there.
Aux 2 is a 0-5V input used for our Torch Height compensation feature. This is an advanced feature that requires a compatible plasma cutter with a 50:1 divided output. The Software for that is still in Beta development so it requires an unlock code to use.
