Sorry I pressed submit to early, the discussion is here

And I'm quite desperate to have at least one person to test.

Mesa is pretty much the standard, firmware sources are open source, as you have found. Pete is rather open with his hardware designs, there are 7i92 clones on Ali express.
If you really want to have a look at well evolved ecosystem I suggest you check out this topic

This has evolved into the riocore project.
It may be an idea to contact Ollie and discuss enclosures and such. Whilst he has designed some boards his energies are mainly taken up by the firmware and software side.
So rather than another project from scratch, I honestly think offering your hardware skills would be awesome to take that project to the next level.
I'd even like to offer my help, I've been working on a custom RPi5\4 image based on the RPi build system, rather than another build system, that is basically exactly the same to setup on Raspberry Pi as a standard image.

Ja im Home Ordner ist alles vorhanden. Es wird nur nix angezeigt. Und auch RMB macht nix

Anybody can build linuxcnc from source. I did a video guide. studio.youtube.com/video/Oe4Hfq3G2_A/edit
 

Once you have isolated cores, Real time applications (like Linuxcnc) will run on one of those cores. More particularly, the RT servo thread will run there. I think user space parts will run on non isolated cores where there is no need to be in time...

Gut, dann hat es immerhin kein Upgrade gemacht. Ist der Desktopordner im /home Verzeichnis zu finden?

It's the IDs that are the issue which are hard coded into the driver. 2.9.7 won't help.

Try the wheezy ISO from the downloads page, tho it will limit the version of Linuxcnc you can use. That really isn't an issue as it will work fine. Actually there's a few members that run earlier versions.

I personally think that modern Operating systems need more than 2 cores to  run  Linuxcnc these days. Give RTAI for 2.94 a go and see how you go.
I have no experience.

Thanks I’ll be sure to check this.

Linuxcnc 2.9.4 was released to fix some things with with XHC USB pendants. Perhaps an upgrade will fix things. Here is how to get it on Trixie
 

There may be more than the usb product code that differ between them.
Here is where to change github.com/LinuxCNC/linuxcnc/blob/fb1480...-whb04b-6/usb.h#L311
Then build linuxcnc and run-in-place.

Mesa just shipped product to Welectron  and Eusurplus

In addition Eusurplus has 7I97Ts in stock

No LSB modules are available
Distributior ID: Debian
Codename: bookworm

2. When the clamps are release and the scale is plugged in and the NC- ready is on its almost as if the mesa card sends out a voltage causing the motor to “bump” which causes a joint error. If I unplug the scale and still leave the clamps off the machine runs fine and the table is steady doesn’t drift. 

If this is a analog system and you prevent motion, Normally you would need to disable the PID
feedback when locked (especially if there is any I term)  Otherwise a large output can develop
as the PID "fights" against the apparent resistance to motion.
