Plasmac parport connections

It would be parport.0.pin−<n>−in or parport.0.pin−<n>−in-not.

I don't know what that error means.

If you are using a frequency then you probably need to feed that into an encoder then use the velocity output of the encoder for the arc voltage.

Are you using a THCAD?

Can you post your ini file and ALL your hal files and I will have a look tomorrow.

@Bushan
Stop making ofending comments.
What is your native language ?

From the begining:
Do you have a THC like THCAD or Proma THC150 or similar?
From your posts you mentioned several times that you do not have a THC, so why do you insist on using such a config ?
Make a simple config and use the machine, you can use a simple DC motor instead of the Z axis motor with two switches to lower or raise the torch while cutting.
For PlasmaC you need to have a working normal config then use the PlasmaC manual to see what you need to edit and what to copy where.
