Update LinuxCNC 2.9.5 on debian 13

Category: Installing LinuxCNC

Thank you for fixing this, Andy, the new key works just fine!

However, the debian package itself seems to have a broken python3 dependency. I'm on the latest Raspberry Pi OS Lite (which is basically trixie with a custom kernel and a few Pi-specific tools installed). Any particular reason for the arm64 package to want python3 < 3.12? amd64 one depends on 3.13, and so does linuxcnc-uspace 2.9.4 that comes with trixie.
$ sudo apt-get install linuxcnc-uspace

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 linuxcnc-uspace : Depends: python3 (< 3.12) but 3.13.5-1 is to be installed
                   Depends: libboost-python1.74.0 (>= 1.74.0+ds1) but it is not installable
                   Depends: libboost-python1.74.0-py311 but it is not installable
                   Depends: libgpiod2 (>= 1.5.1) but it is not installable
                   Depends: libpython3.11 (>= 3.11.0) but it is not installable
                   Recommends: linuxcnc-doc-en but it is not going to be installed or
                               linuxcnc-doc
                   Recommends: librsvg2-dev but it is not going to be installed
                   Recommends: hostmot2-firmware-all but it is not installable
                   Recommends: python3-pil but it is not going to be installed
                   Recommends: python3-pil.imagetk but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
E: The following information from --solver 3.0 may provide additional context:
   Unable to satisfy dependencies. Reached two conflicting decisions:
   1. linuxcnc-uspace:arm64=1:2.9.6 is selected for install
   2. linuxcnc-uspace:arm64=1:2.9.6 Depends python3 (< 3.12)
      but none of the choices are installable:

Tipps für aktuelle LinuxCNC Hardware gesucht

Habe ich das mit der Konfig der mesa Karten richtig verstanden, dass ich zuerst herausfinden muss wieviele Ein- und Ausgänge ich brauche um dann die passende Konfig auf die Karte zu spielen?

Installiere linuxcnc auf den Raspberry und starte einfach pncconf, dann kannst du dir die Mesakarte aussuchen und siehst selber was man braucht.
Du brauchst die Steigung deiner Spindeln (der Hersteller gibt 0.00375mm/schritt an, also vermutlich 1.5 oder 3 mm).
In pncconf werden Takt/Richtung für die Achsen fix vergeben sein, du musst den Pins nur korrekte Achsen zuordnen. Dann noch angeben an welchen Pins welche Endschalter hängen und das war eigentlich schon alles. Also praktisch nur von deiner HAL-Datei abschreiben.
Oder du schaust hier:  linuxcnc.org/docs/html/config/pncconf.html
