Help with adding PlasmaC to base config + 7i76e

Once the base config has been set up, I'm having a bit of trouble getting PlasmaC to load after I run my base config through the configurator.



I've tried switching things around several times without luck and left wondering which values I should be entering here and whether I should be selecting 0 or 1 for arc voltage mode (I have a THCAD 10).



Any guidance is greatly appreciated!

That should be the exact input pin on the 7i76E where the float switch is connected, like
hm2_7i76e.0.7i76.0.0.input-00
Same for the torch out, the exact output
hm2_7i76e.0.7i76.0.0.output-00
And for the THCAD you have to enter something like
hm2_7i76e.0.7i76.0.0.encoder.0.phase_A
Chang the input/output to what you have it wired to.
Start the normal config, from the Machine menu click on "show hal configuration", there click on pins and search fro the exact numbers and encoder.

hm2_7i76e.0.7i76.0.0.encoder.0.phase_A


You would not use the A hal pin on the encoder for a THCAD,
but rather the encoder velocity signal:

hm2_7i76e.0.7i76.0.0.encoder.0.velocity

So I am safe to stick with arc voltage mode 0?

Sorry, my bad.
Just got news that THCAD's i ordered are in Switzerland ! Messed my day, or evening.

If your machine does not have an Arc OK (Transfer) output then use mode 0, if it does then use mode 1.

hm2_7i76e.0.7i76.0.0.encoder.0.velocity


Sec 27 of the plasmac manual refers to adding

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

for my THCAD10 somewhere in the base machine hal file. Just at the bottom of the file is okay?



I pasted to the bottom of my working base file:



Now upon launching the file created in configurator I get:



What do I do from here?


If it makes any difference I'm running the Mint .iso I downloaded from Linuxcnc package repos for Mint 19.x Ubuntu 18.04 aka Bionic Beaver & Mint ISO .

You have:
setp hm2_7i96.0.encoder.00.velocity

It should be:
setp hm2_7i96.0.encoder.00.scale -1

Here as you can see I updated the base file but I'm still getting errors.

I think they need to be:
setp hm2_7i76e.0.7i76.0.0.encoder.00.scale -1
setp hm2_7i76e.0.7i76.0.0.encoder.00.filter -1
setp hm2_7i76e.0.7i76.0.0.encoder.00.counter-mode 1

arc-voltagein should go to hm2_7i76e.0.7i76.0.0.encoder.00.velocity
