"The 300V version of the THCAD has all input divider resistor on board and can connect directly to the plasma voltage of touch start type torches only."

this was the section of the description on the Mesa site that confused me.

I had also tried, same problem

Maybe add a debug output to the autostart command:

... >> /home/axel/autostart_log.txt

Usually a good idea to share the errors you are getting. Saves people trying to help a lot of time.

Scratch start has no HF nor HV pilot arc, it needs to be dragged on material to fire.
THCAD 300 would work fine for your plasma (i use them on HF/HV start despite warning all not to do that, it just needs to be wired in the right spot), and so will any THCAD, just get 2 of 1MOhm resistors rated at 2W or 5W and wire one on each arc voltage wire.

Out of curiosity, how much is a RPI and a good touchscreen these days?
Wondering as i got a Lenovo X1 Carbon Yoga for 120 and a Lenovo Yoga Y370 for 220, bot work for LinuxCNC with Mesa, both have 120Hz touchscreens, very high quality ones, very good keyboards, and both do over 4-6 hours on batteries.

Rod  i did some digging and found out that this Machine has been done with THCAD before. the person that did this has some YouTube videos and i found this image on here. this is basically the exact same setup i was going to do minus the THCAD since i was not sure on that part; I watched the videos and in the video he said the THCAD-300 would have been a better choice with this machine. the only thing i noticed was that the THCAD-300 seems to be for only scratch start HF machines? this machine has a 1:1 ratio but has the blow back start so which would be better the THCAD-2 or the HTCAD-300 ?

Also, USB C should work with a USB C to A adapter, but in your case only with USB A 3.n version, not with USB 2 versions.
USB 1, 1.1, 2 use 4 pins, USB 3 uses 9 pins, Type C uses 18 pins, but some are for monitor signals .... so is the USB C used for monitor and touch? If yes, then no adapter works. Cr@p, only recalled this while typing.
 

The instruction pamphlet goes on an on about the virtues of using a full featured USB-C port because no HDMI connection is required, video, touch sound all over that single connection, however Pi does not have USB-C.

The instructions then go on to state if you connect the ports in a particular order that you can get the touch working in tandem with the HDMI port but I have tried all combinations and perhaps this might work on a Windows machine (I doubt it), but looks like I need to find another touchscreen, one that does not rely on a USB-C port for the touch signals.
Thanks

You can check on github:

2.8:
github.com/LinuxCNC/linuxcnc/blob/2.8/src/hal/components/pid.c

2.9:
github.com/LinuxCNC/linuxcnc/blob/2.9/src/hal/components/pid.c

[edit]

the differ by two commits:
github.com/LinuxCNC/linuxcnc/commit/bab0...0737b15cba7bdce50a5d
github.com/LinuxCNC/linuxcnc/commit/a882...ef79379518f8dd3973f9

[edit 2]
you can compile 'pid.c' ('sudo' is not required if you have a locally built installation (RIP-install)):
For the 'halcompile' tool you need to have the 'linuxcnc-dev' package installed

that kinematic does not have a pin called 'skewkins.skew'. Try 'skewkins.skew-y':

 

It is available: packages.debian.org/trixie/arm64/python3.12

Did you try to install with: sudo apt install linuxcnc-uspace ?
Otherwise first: sudo apt install python3.12

This is my dog now, fluffy white thing good only for cleaning shoes with it

And this is what it did to my hand a while back

Topic those pictures are from and dates of bite marks here:
forum.linuxcnc.org/show-your-stuff/38547...ild?start=110#171915

Yes this all actions I did,

and I have some machines with custom drivers such ass e1000, e100,8139too ... but I did install 2.9.2 over rods steps and just reinstall ethercat master over thread and it works from first shot ... after
but now I tried everythnig what is in the my fantasy and it is still in the

This one has another problem which its python is 3.12 and linuxcnc cant be installed on it!
I did many efforts on it since you provided this link in order to downgrade its python but still no result.
