Z axis

So i started over & set the low volts to 60.
at a scale 50:1 i get a reading now 143 and if at a scale of 75:1 i get 219 see attachment.

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.

That's the plan, I will try at some point this weekend....I was reading some forums and will be trying their suggestions. I should have waited and saved up for a Hypertherm...

thanks for everyone help up to this point.

Throwing in the towel with this Mesa thcad-10 , And plasmac, Very disappointing!!

Sorry we couldn't help you.

Yes we are sorry to see you go too. It looks like you have got through the Plasmac setup but have hit the wall with getting your plasma machine to work. Don't expect that to be any easier on another controller or THC.

As you don't have an ArcOK signal on your machine, Plasmac attempts to fake one for you. It does that by turning on an ArcOK signal when the arc voltage excennds the low volt threshold. That threshold needs to be high enough to confirm a good arc has been triggered. Around 60 volts is a good starting point.
