setting up thcad

ok so i have built a semi working plasma machine with a mesa 7i96, thcad10 and a powermax 45 but it seems i forgot to set up the thcad 10 in linux cnc. the machine will go as far as starting an arc but wont move because i does not detect any voltage. how exactly do i add the thcad to my machines .hal file i am extremely new to linux and computers in general and dont understand where to add the: setp hm2_7i96.0.encoder.00.scale -1
setp hm2_7i96.0.encoder.00.filter 1
setp hm2_7i96.0.encoder.00.counter-mode 1

also can i add it at this point or will i have to add it to a base machine and run the plasma configurator again?

You can add them in either your <machine>.hal file or your <machine>_connections.hal file.

Provided you have given the correct pins to the Configurator then you won't need to run it again.

so how do i add it to the file do i just literally copy and paste it in? if so where would i do that?

In your home directory you should have a directory named linuxcnc then a subdirectory named configs then a subdirectory named <machine>. In that directory you should have a file named <machine>.hal. Paste the code into that file.

<machine> is the name you gave the machine in the Configurator

does it matter where i paste the code in the file?

Not really, somewhere in the file will be a block of code with a few lines starting with addf. Paste it as a seperate block after that one.

Thank you so much sorry for the dumb questions, im slowly catching on with the computer side of this project.

You are welcome.

There are no dumb questions but occasionally you may get dumb answers.

OK so now i have officially cut my first part but i am still having a problem with the thc. The voltage reading on the plasmac dashboard is constantly scrolling widely like from -900 to +900 even when the machine is idling so the only way i can cut is with the thc is disabled. i used the online calculator for the scale and other settings for the thc and im pretty sure i have that part right because even if i change the numbers i still get the same thing. what could be causing this?

Is the THCAD connected to full arc voltage or a divider?
Can you zip your config and post it.
