Try the voltage in between 80 and 85, Proma THC can be set to be sensitive to -+1V.
Also set the TEST time longer on the THC so you can clearly identify if the UP/Down signals are correct. You can do that by holding both buttons on the THC till you get TST then release and click on the UP till you get to 10, that will give you 10 seconds to check the signals on Linuxcnc screen.

Yes there is, ferror should be for high speed or rapid moves, min_ferror should be for slow moves.
I am a bit fuzzy on that, so you should confirm that.

Based on this:

limiting ferror = maxFerror/limitVel * vel


If ferror < minFerror :
then OK
else:
if ferror < limiting ferror :
then OK
else:
ERROR
( this is from the source )

I think that there is no difference.

This has been moved to the thread below where the other configs are also located, for stepper and servo step/dir systems, for use with Mesa FPGA boards.

You have to use inkscape to produce the gcode.

That is the way it should be, without ArcOk there os no cutting going on, so it does not move the machine at all untill it gets that signal.
Wire the arcok signal to torch on for testing, you can do that in hal or a wire to the parallel port from torch out to arcok in.
