You mentioned that you were switching over to Linux for your plasma cnc. I am currently in the process of building one and I am a bit confused on how to setup all the files for it through LinuxCNC. I am using a Mesa 7i76e board and Nema 23 stepper motors. Could you help guide me in setup?

You would connect the trigger circuit of the plasma torch to a relay and then the input of the relay to a digital out pin on the Mesa 7i76e. When the pin on the Mesa board goes high, the relay closes, and the torch is turned on.

This is the machine that I purchase. ( Cut60L). The description says Non HF and blowback start but looking at the torch shows to be a HF torch (no sping electrode). Here is the link of the machine that I purchased (Cut60L).

Thanks. Have you ever tried using a cnc milling machine to act like a plasma table? I was thinking of attaching a long pole to the top of a CNC milling machine table and attach a plasma torch to the end of it and let the cnc X Y axis control the movement of the torch and use the Z axis to press a switch to turn on and off the torch mechanically. Just an idea.
