Koike Aronson Plasma Conversion - sanity check on Mesa board selection?

By way of update, I got the machine cutting today, thanks for all the support in this thread as well as all of the others I poured over the past week.

I ended up removing the Animatics Smartmotor from the original setup and replacing it with a stepper motor I had on hand, the smartmotor was just a little too dumb for my taste.

The one remaining item I have it to get the THCAD2 setup. I'm unclear on how the encoder mapping works when I have the 7i96s + 7i77 setup together. It appears as though the 7i77 takes encoder slots 0-5, but I also have 6 and 7 listed in halshow and regardless of which I configure the default value that is detected is -22 in plasmac. Seems like I'll have to do a bit more digging...

Using PlasmaC or QtAxis PlasmaC or QtPlasmaC?
-22 should mean the THCAD is connected and sending pulses, the scaling and offset are not set in the settings tab.
Does -22 fluctuate?

I'm using QtPLasmaC.

I have these in my *.prefs file:

[PLASMA_PARAMETERS]
Arc Voltage Offset = 3071.8750
Arc Voltage Scale = 0.00797309

Unfortunately my setup (7i96s+7i77) isn't supported in PNCCONF so I've had to assemble everything by hand using various sources, so it's very likely I've messed this up

Do I need to include the calibration values elsewhere as well?

iirc the -22 is very constant (this is while not cutting, FYI)

Thanks!

What does the encoder 6 velocity pin read?

I think my understanding of the encoder mapping was incorrect. I had it connected to the encoder plug on the 7i96s and couldn't get any readings off of it (I used a bench supply to simulate arc voltage). I switched it to the 7i77 encoder 2 and it works perfectly from there. Thanks for the assist!

That can be changed in hal to any of the encoders.
