No success obtaining value of encoder from THCAD-10

i believe i might be missing the frequencies and some other values which are asked by a prompt in QtPlasmaC. But im using PlasmaC only, which only asks for the voltage encoder port.

i wouldn't know how to change these values in the hal file directly, so i am trying to switch to qtplasmac (which seems to have an even better user interface)

Tried running " qtplasmac-plasmac2qt " in a terminal to switch from plasmac to qtplasmac but the command didnt work.

Seems like you’re just starting out, so I recommend using pncconf and choosing qtplasmac as the screen which will do everything for you, including the calculations for the thcad.

i had no idea pncconf had a pre-made config for qtplasmac. thank you, will try now.

yes I'm starting out on linuxcnc! i have a bunch of old non-functional industrial machines; mills, plasma oxy, lathe, and a bunch of others my dad left me a few years back, and have decided to retrofit most of them. the first one is plasma and oxy and the next will be an ATC mill retrofit.

guess i'll have to update from linuxcnc 2.8 to 2.9.

Do you mean this ? 
Should i try to paste this "somewhere" along the hal file in order for it to work?

If you look at the encoder velocity in halshow and its not bouncing arround near 3800 (eg its static), there are some settings missing in your hal file. I think they are covered in the Plasmac docs.

Code:

loadrt encoder num_chan=1 setp encoder.0.counter−mode 1 setp encoder.0.position−scale -1 addf encoder.update-counters base-thread addf encoder.capture-position servo-thread net arc-voltage-raw parport.1.pin-04-in encoder.0.phase-A 

That is the example for a parallel port, I thought you stated you had a 7i96s.

I thought you were moving over to QtPlasmac? Yes, that does require you to be on 2.9, but you also get to use the pncconf that has qtplasmac as a screen by default. That will do all of this for you.

I made a guide that in addition to installing MX Linux, may help you get QtPlasmaC going. You mentioned you are pretty new to linux, so following the guide as a whole may make the transition a bit easier for you.
