Erstmal ein Gruß in die Runde,
mein Name ist Olli (Oliver), 54 Jahre jung, seit 35 Jahren CNC-Fräser und ich bin neu in Sachen LinuxCNC.
Ich habe Debian 12 und LinuxCNC mit dem Probe Basic Screen Lathe installiert, soll halt für ne Drehmaschine sein.
Hardware ist ein Mini-PC Fujitsu Esprimo Q956 mit Core i5-6500T und 16 Gb RAM.
Nach der Installation habe ich den Latency Test gemacht und der war grottig
Im BIOS habe ich alle Stromsparfunktionen abgestellt.
Was kann ich sonst noch tun?
Besser auf eine andere Hardware umsteigen?
Danke und Gruß
Olli

Das ist die normale kernel, braucht die RT kernel.
-
That is the normal generic kernel, it needs the RT kernel to run machines.
What DE version (Mate, xfce, gnome) ?
Did you install from the net ISO or from a DVD/CD ISO image?
When installing LinuxCNC, did it fail with errors pertaining to mising "raspi" stuff?
-
Turn on the PC, hold down the Shift key, at the GRUB menu enter "Advanced options for .... " see if there is an entry containing RT in the name, choose that and press enter. Now do a latency test.

thank you for answering but the installation ends with:
"Sub-process /usr/bin/dpkg returned an error code (1)"
I will reinstall the system again

Thank you,
ok, I thought it was the right kernel, that explains a lot of things of course.
I use xfce4. I don't remember which image I took, but I think it was the small installation image.
The advanced options don't show any RT

Solution:
-Open terminal
-type sudo caja
-open /etc/ folder
-Press ctrl+f and type z50*
-it will find 3 files, delete all 3
-do a sudo apt upgrade again
Everything works, so far.
Reboot.
EDIT:
If using xfce
sudo thunar
instead of
caja
-Open terminal
-type sudo caja
-open /etc/ folder
-Press ctrl+f and type z50*
-it will find 3 files, delete all 3

Error fixed, it was of course due to the non-existent Real Time Kernel.
I have completely rebuilt the system.
Thanks again for your help
Olli
Fehler behoben, es lag natuerlich am nicht vorhandenen Real Time Kernel.
Ich habe das System nochmal komplett neu gemacht.
Vielen Dank nochmal fuer eure Hilfe

If you plan to use Mesa boards, try
latency-histogram --nobase --sbinsize 1000 --show
latency-histogram --nobase --sbinsize 1000 --show

Yes, Mesa Boards,
7i92TM -> 7i76 -> 7i85
Ok I will try that, but it will take some time because I still have to build the machine, but I want to finish the software so that it is ready to use.
