Probably been over 10 years since i last tried Xenomai, and on one PC it was better than RTAI, but on all others (4 or 5 PC's) it was worse regarding latency, and on 2 it did not boot.
Not good memories, but that is all i have.

If those are the same files being called repeatedly, try VCP panel, pretty sure it can run MDI and gcode:

linuxcnc.org/docs/html/gui/pyvcp-examples.html
in google

swivel unions have a lot of types

Any official ISO, and any official LinuxCNC deb/install has several included sims (simulators) that you can use on any PC, even without installing them, just boot from the USB stick and use for testing (and even run actual machines).

Moved to "driver boards".
I am pretty sure they are perfectly usable, but you should wait for someone with more authority to reply as i have never actually used any of those.
Thank you.

When did you download the ISO?
Can you download it again and give it another try?

Couldn't find any spots showing voltage.

Strange, there is always, always some small readings of a few Volts, so i would venture a guess at measuring at the wrong places, although there are no right places, but still, one lead from DVM to electronic/control ground or zero, be it Mesa board and/or power supply "negative" side, the other on grounds on power supply, case if metal, wire shield, etc.
And you will have to find a DVM with memory or use a scope to check the mains voltage when the plasma triggers.

Does sound like an EMI issue.

Have you tried debouncing the limit switch signals?
 ( This can be done with the hal debounce component or with some
hardware, a hal parameter )

I am currently having the same problem. After it telling me what my key was everything else I did much the same as michaeln I kept getting conflict messages, could not examine sources, etc. I am new to this so where and how would I remedy my key issue.and I don't have the Synaptic option that I can find.

It’s been a little over 10 years since I last used LinuxCNC; back then it was for a one‑off prototyping project at work. Now that I’m retired, I’m thinking about getting back into it for some hobby projects.While going through some old boxes, I found some MESA cards I had kept as spares: 5I22, 7I33TA, and 3 × 7I42TA. They were stored properly and should be in good condition. I’m not sure how current this generation of hardware is anymore, and I’m reluctant to start a new build around something that is obsolete. Before I decide what to do with them, I wanted to ask: do these boards still have practical value for anyone running older systems? If so, I’d likely sell them rather than let them sit unused.As for new projects, I’m considering a few possibilities:

• 3‑axis router, for wood and softer materials. Likely steppers, though I may look at servos depending on what I decide for requirements.
• I have a CO₂ Iradion laser + PSU, new in the box. Could be a candidate for a laser cutter/engraver build, or I may just try to sell it if there’s still a market, as my primary interest is the router.
• Guitar pickup winder, something I’ve always wanted to build, and a simple way to get back into LinuxCNC.

Before I dive into researching current LinuxCNC‑based routers, laser systems, or pickup winders (does anyone know of one), I figured I’d ask here first. Any pointers on modern hardware choices, project examples, or insight into whether the MESA boards I have are still useful would be appreciated.

I am.

However, my lathe is not completely finished and I'm finding that I will need to heavily modify PB or switch to another GUI (likely Flex) as my configuration and GUI preferences are pretty specific.

Hello all, I was hoping to get an idea of who all out there is using probe basic lathe currently?  please drop a line and let me know if you are using it!  

thanks all!!

Hello Tommy:

   thank you for the fast reply.
I am not sure which config your referencing to?
There is this PortTest demo.
Do you have the path to the config script. Because under the 
/usr/realtime-5.4.258-rtai-amd64

bin  calibration  modules  share  testsuite


This is all i see and thing to do with config

thanks
Mike
 

works on aliexpress and the Temu normally now, Aliexpress has customs duties..otherwise nothing has changed here for 3 decades, it's just getting worse and worse, I have the option of purchasing from EU countries that don't have customs duties but have taxes so it comes the same
