Z axis

Thanks, I hope you enjoy it.

You most probably have: in your halfile, it should be: it is the ONLY -1 in there, but if you are happy to have your offset at -3781.25 then you can leave it as it is.

When I do this I run number all the way down to 0 so the voltage reads 0 and I’m back to nothing square 1.

I’m at a lost with the Mesa thcad—10 board

Strange, Your numbers are correct and the hal files look good, the only thing I can think of is the divider is not really 50:1

A -73V variation from what it should be is a lot.

Have you checked that the THCAD jumper is definitely F/32?

EDIT: definitely a THCAD-10?

Here a couple pictures, to make sure

My plasma machine has 3 out put for voltage.
1/50, 1/16 and raw arc voltage with 100kohm resistors in series.

And I just triple check my wiring and I Am connected to the right pin 4 and 6 for the 1/50
