What does the arc voltage read?

Note that you may need to use a negative encoder scale number depending
of the state of the B encoder input

Is the encoder counter-mode set to 1

On the DRO in plasmac it does not read anything, I am not getting any voltage.

I check it with hal show and some of the encoder pins just alternate between 0 and 1 constantly even when the torch is not fired.

The input hm2_7i76e.0.encoder.00.velocity stays at 0.

Is the encoder counter-mode the same thing as the operating mode? If so it is set to 1.

No, it is the counter mode in the HAL file, something like:

I have checked all of the hal files in the config of the machine folder and cannot see a: setp hm2_7i76e.0.encoder.00.counter-mode 1

When I set up the basic config in Pnccof the first time I specified the pins for the THC, Ohmic input, Ohmic enable, Float switch, and then I ran the configurator as used the same values. I then tried running Plasmac and got a start up error message saying those pins were already in use.

I then ran Pnccof again without specifying these pins and let the configurator set them. That allowed me to run Plasmac.

Now in the original machine hal there is no mention of the encoder (because I did not set it in Pnccof),

I am a little lost here at the moment, When I set the encoder in Pnccof it gave me errors when I tried to start the program because it set the hm2_7i76e.0.encoder.00.velocity in the hal.

Once I get this sorted I want to use my experience to help write a decent step by step guide with the mesa 7i76e outlining my mistakes and how I resolved them.
