Did you also chose QTPlasmaC as the GUI?
(maybe that matters also)

Hi,

I added support for the Mesa 7i95t to the pncconf wizard (private_data.py with changes attached) and it seems to work ok other than needing to rename the inm to inmux pins for the 7i95t.  However, the THCAD configuration screen doesn't appear even though I assign an encoder input to arc voltage.  I must be missing something in looking at the code but I don't find where self.d._arcvpin that is used to control the display of the THCAD screen is ever set to anything other than None.  I have QTPlasmaC selected as the gui. Any help is appreciated.

Solved:  Attached updated files with the THCAD tab working.  The pages.py and private_data.py go in /usr/lib/python3/dist-packages/pncconf and the pncconf.txt should be renamed to /usr/bin/pncconf.

Hola tengo varias dudas.
mesa 7i96s, thcad 2, plasma stamos 125h cnc, linux cnc, qtplasmac.

El plasma tiene 2 pines que ivan al gatillo de la antorcha y otros 2 que son el arc volt.

Pa primera duda es si puedo usar los pinos del gatillo para encender antorcha ( por lo que e visto por el foro si con un rele de estado sólido ) lo medí i salen 10v mi duda es como tengo que cablearlo. ¿E visto estos reles podrían valer?

La segunda es que no me sale la configuración del thcad en pncconf pero e visto algunas personas que lo tienen.

Y tercera cual es la manera adecuada para la conexión a tierra tengo cables blindados. 

Puedo mandar fotos de lo que tengo si es necesario 

Gracias soy muy nuevo

Hola a todos soy muy novato en esto pero lo intento.
Monte un  plasma cnc con mesa 7i97s que consequi hacer que funcione bien hasta que le puse el thcad2, le hice solo 3 pruebas de antorcha y los motores ya no se mueven, save alguien si puede ser que se haya quemado la tarjeta 7i96. Se conecta a linux puedo encender antorcha pero no se como verificar cual puede ser el problema, gracias.

Mesa 7i95T or 7i97T would be all in one, but price might be on the high side for what you need.
You can safely use just a Mesa 7i92T, but must be careful with wiring as the pins are sensitive.
Having said that, i have Mesa 7i92 wired on several of my plasma machines, meaning very high interference environment, and the THCAD is wired with 5-7 meters if cable directly to Mesa 7i92 input, yet i never have issues, ever.
This does imply proper shielding and grounding is a must.
In your case just having good shielded cables and grounding the shield only on the Mesa side inside the box should be fine.

ARCOK is derived from THCAD. My unit has arc ok output but the relay on the inverter board is not working so I'm using mode 0 for now. ark-ok-low is 60 and ark-ok-high is 200. Pilot voltage seems to be around 157 so maybe I could set ark-ok-high to 145 or 150. I've been testing on a scrap piece of 1/2" I had so not sure if the pilot voltage changes based on material thickness.

Is ARCOK signal wired to plasma or derived from THCAD?
