Thank you! Worked perfectly

You might also want to consider servo drives from Delta, Rexroth, or others that support direct connection of the linear encoders to the servo drive for full closed loop operation.  This is combination with absolute encoders on the servos is how I think most new machines are doing it...at least the ones I have seen.   They could be controlled from either Mesa or with Ethercat.

You can just replace the private_data.py file in /usr/lib/python3/dist-packages/pncconf with the private_data.py that is attached to my post. I would backup the original file first just in case.

Well MesaCT doesn't support QTPlasmaC at the moment. I have done some work on supporting it but haven't heard from JT if he's interested in bringing those changes in if I make a pull request.

Nice effort! How would one apply the changes to get 7i95t support in pncconf?

What are pros/cons of using pncconf vs mesa CT? github.com/jethornton/mesact

Sorry I should have had that in my initial post...yes I have QTPlasmaC selected as GUI.

Si la señal es cc lo mediré por tenerlo en cuenta pero si es mas seguro con el rele ssr creo que lo pondré.

Otra pregunta crees que es necesario tener picas de tierra separadas una en la caja de controles y otra en la mesa o no hay ningún problema en estar en la misma?gracias por todas tus respuestas

El plasma es trifasico

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

when running said bitfile and using

loadrt hm2_pci config="sserial_port_0=7i77,2500000 sserial_port_1=7i84,2500000"

it doesn´t show a second sserial device when:

sudo mesaflash --device 5i25 --readhmid | grep -i sserial

Maybe i am using the wrong nomenclature or baudrate?

Yes, if you don't know the signal characteristics, 
an external SSR would be safest.

Though if it is a DC signal, you can measure the
current with a DVM (Start at high current range and work down)

No creo que pueda saber si necesita mas de 100mA lo tengo que conectar al gatillo que tenia la antorcha 

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.
