Thanks for your reply Tommylight.
On tomorrow or in 2 days i will tell you the exact version, but i remember it was Kernel 6.3. rt something..
Hypethreading option is not available in Bios. 
This PC was working perfectly fine with Wheezy and Linuxcnc 2.8.x . I also remember that i reinstalled wheezy and tested the machine after first latency problems on Debian12 and there were not problems. So, problems started 100% since Debian12.

I can not justify breaking a perfectly working machine for OneDrive even with a gun pressed to my head

100% right, but i was forced to do so, because my SSD card broke. I remember that Linux didnt started anymore, from one day to another. 

Short history:
At the beginning of my cnc experience i used a USB stick to tranfer files, but someday i got the ethernet working (it was maybe 2018 or so). Since then i used Email or if i had a lot of files then i used USB stick because i remember that the Browser was very slow, which was very annoying for multiple files.
I did it that way for couple of years (its a hobby machine, not using it every day)until i thought that it would be a lot more comfortable and quicker to have them on a server or share the files on the windows pc. I dont know if i used Samba to setup file sharing, but i believe so. This has worked mabye for 1-2 month. Suddenly it did not work anymore and i could not fix it. Then i thought about OneDrive, because i have used it already for other things. I managed to get it working and i had a OneDrive folder on the Desktop, so i somehow installed it on Linux. This worked super well, but also just for couple of month. From one day to another it stopped working. Browser did also not anymore work. It was not supported anymore or so. Of course i have tried to fix it by installing a different browser, but nothing worked and shortly after my SSD broke. No joke.
So, i think you can imagine how pissed off i was. The amount of time i have already spent with fixing linux problems is unimagineable , so i am already a bit allergic to it. 
It is like this:
1. You try installing a different browser for Linux, so you google it with the correct Linux version/kernel version.
3. You find a tutorial and first step says: Open Terminal and copy past this "xadsasddadqd" command.   
4. FAIL, because xxxx1 is missing.
4. You look for a tutorial to install xxxx1
5. For this you unfortunately need also "xxxx2"
6. .... and so on
This is how it was with the wheezy version. Problems after problems and i just wanted to use Linuxcnc, have one app like mousepad and ethernet browser or some kind of file sharing setup. But just for those things i had to make a lot of fixing work. 
I believe with Debian12 there are not this kind of problems anymore, but now my LATENCY is fuxxed up.. 
The funny thing is, i always loved to do some computer fixing stuff, solving problems, tweaking etc. but Linux managed to make me hate such things. 

***FOR ALL BEGINNERS WHO ARE READING THIS:  Its not about LinuxCNC! LinuxCNC is working perfectly and always was working perfectly, also i have LinuxCNC on my Lathe with Mesa 7i76e and its working perfectly!   If i would start my Linuxcnc experience from Debian 12, i would now only need to get the Latency fixed, nothing else. The previous versions i had (wheezy) were for sure versions specific for Linuxcnc, with only those things installed that are needed to start LinuxCNC, thats why i had so many problems and bad experience.

Okay, enough for today. I wait for the Radeon VGA and try then if it works. If not, i think i just buy the Mesa card, because going back to wheezy is, i believe, no option for me. Maybe its possible to get file sharing to work on wheezy, but i dont want to even anymore tried it, because if i do, i will again sit 12 hours in the workshop trying to install Samba, and the 127 other things that are needed  while my hands are freezing. (someone i always have Linux problems in wintertime)

I converted the controller of an old plotter that was burned out. By trial and error method we managed to get it working.
 I use 0.3mm kanthal wire.The length of the wire is 1.5 meters.
 It does not break very often but it is almost always the least appropriate moment when cutting large files.  And my works can be cut even 1,5 h. I use styrofoam for initial molds for plaster decorations.  (Maybe a little from exaggerated economy I use it too long).
I don't know the tension force of the wire and it will be difficult for me to measure it.
I don't know the temperature of the wire either, but I know that with the hardest materials in the dark it doesn't glow. At least that's the setting I use.
The wire is powered by 90V.
I have the PWM set to 100Hz.
Whether the control is needed I don't know now I work without it, but in the old machine it was and sometimes I saved a large piece of material.
I am also attaching two photos from the manufacturer's website of my own now I don't have until the weekend I will be in the workshop.
