Update LinuxCNC 2.9.5 on debian 13

Category: Installing LinuxCNC

With your 20 years experience if you really want 2.9.5 on arm you can always build it yourself.

As for the version differences that will depend on the system the packages were built on.
Was there any reason, apart from the official arm image being based on Bookworm, that you went with Raspberry Pi OS Lite ?
Does that give you the choice of Wayland or X11.
Look we get a lot of users with varying degrees of Linux Experience, as we can't tell your experience usually we start advice with the basics. So no it's not a waste of time starting with said basics.
From memory when I attempted to build an RPi image based on Devuan, based on Trixie or maybe unstable, there was an issue with the libgpiod library. At the time the libgpiod driver would not compile against version 2.0 so I abandoned that idea due to that. As far as I know I'm unaware of that situation has changed. Bear in mind that there are some issues that affect Axis in 2.9.5 and 2.9.6 that have been well reported on the forum. It would appear they have been resolved but looks like we need to wait for a 2.9.7 version.

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.

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

Was braucht so eine Karte an Stromversorgung? Die 24V werden doch nur benötigt wenn die Stepper (+Treiber) da direkt

5V. Die Treiber haben eine eigene getrennte Versorgung, die du ja schon hast. Wenn die Maschine per DB25 Kabel am Parallelport betrieben wurde, hat deine Maschine auch ein BOB, um den Parallelport zu schützen.
Das gezeigte BOB aus China ist nicht nur völlig nutzlos und überflüssig, sondern würde bei Direktverbindung die GPIO-Pins des Raspberrys ausknipsen, da die nicht 5V-tolerant sind. Das "Parallel Hat" von byte2bot hat deswegen vier Pegelwandler von 3.3V auf 5V und umgekehrt verbaut. Wenn man auf die verzichtet und die Maschine direkt am Raspberry betreibt, muss man die Eingangssignale auf 3.3V bringen.
Weiters muss man die Eingangspins gegen negative Spannungen schützen, indem man zumindest jeweils einen Vorwiderstand in Serie schaltet, am Besten in Verbindung mit einer Schottky-Diode mit möglichst kleinem Spannungsabfall (1N5817 oder so). Die Raspberry GPIO-Pins haben integrierte Schutzdioden, die laut meiner kurzer Recherche nur 1mA vertragen.

Die Chinesen scheinen bei deren Karten den falschen Busschalter verbaut zu haben: CBT16211A statt CBT16211. Laut Datenblatt ist das ein reiner Schalter ohne Pegelwandelfunktion, müsste also entweder gegen welche ohne A getauscht werden, oder die Pins dürfen nicht mehr als 3.3V sehen. Die chinesische 7I92 hat Vorwiderstände an den Pins, vermutlich weil den Chinesen beim ersten Test die FPGA-Pins wegen zu hoher Eingangsspannung gestorben sind. Falls die Widerstände 220Ohm haben, weiß ich woher sie die Idee haben

Die Widerstände werden aber vermutlich zu klein sein, um die Maschine da einfach direkt anzuschließen.

Die Mesakarten laufen über TCP/IP. Die Adressen sollten fix sein. Man kann die Adresse der Karte per Jumper von 10.10.10.10 auf 192.168.1.121 oder so umschalten können.

Da deine Maschine noch läuft, musst du die Pinbelegung eh im Computer haben. Ansonsten im Schaltplan oder in der Gebrauchsanweisung nachzulesen. Falls die nicht mehr vorhanden sind, einfach an den Kundendienst wenden.
Wir können aber auch im Forum demokratisch abstimmen welche Pinbelegung deine Maschine hat.

Index for known RPi issues& solutions.

forum.linuxcnc.org/38-general-linuxcnc-q...official-images-only

On board Rpi Wifi does work, version of installed Linuxcnc does not matter, if you used the official images.

Any USB Dongle that works with Debian will work as the image is soley based on Debian with Linuxcnc installed and some stuff from the Official RPi github, kernel sources and so on.

Sorry I can only speak English.

First of all I really want to say thanks for all the work you've put into your projects, you really deserve a couple of beers, if that's your poison

or a least a good coffee, damn mate whatever you like to drink. Honestly thanks.
Haven't had a chance to use it or try it out but it looks great. One of the things that has been missing for the RPi IMHO, would be great to see in the mainline Linuxcnc tree.
Would be great if you could add this to the RPi "mega thread" and I'll add a link in the index.

Now a request for an extra feature, any chance for ADC support. Would be great for things that a user wants or needs an analogue input.

That makes it easier to imagine

It should now also be possible to mix FPGA and RPI/Parport configurations.

Oh, there's a new I2C plugin for the Raspberry with pcf8574 and ads1115 support (digital IO + analog inputs / non-real-time).

NEW BUILD, need help with e-stop in tklinuxcnc

Category: Basic Configuration

For weeks, I've been working on my own CNC machine and have made good progress, but I need help with some small details from experts.The machine is a MicroCarve MV3 with 3x 23-305-DS8A steppers in bipolar parallel mode, connected to a TB6600, which is connected to a Raspberry Pi 4. I don’t have a stop button yet.I’ve managed to wire the motors and Pi to test the axes with a Python script. I also created a minimalist INI and HAL file and started TkLinuxCNC. However, I can’t move the motors because the software shows an E-stop, and despite my efforts, I can’t get the machine to move.I access the Pi via VNC without a connected monitor. The image used is rpi-4-debian-bookworm-6.1.54-rt15-arm64-ext4-2023-11-17-1731.img.xz, updated to LinuxCNC 2.9.6.Friends, I need help. I’ve spent many hours on this and am close to getting the machine running.My test script works; HAL and INI files are attached.Thanks,
Dragan

XHC-WHB04B-04 Got it working

Category: Advanced Configuration

[SOLVED] XHC-WHB04B-6 on LinuxCNC 2.9.6 (QtDragonHD + 7i96S) — Beginner notes
(I am sharing the exact steps I followed, written simply. Many threads assume advanced users; I am a beginner.)My machine / system

Gantry router XYYZ (dual Y motors), work area approx. 1300 x 1210 mm
Controller: Mesa 7i96S (Ethernet, step/dir)
Spindle: 2.2 kW, 24,000 RPM
UI: QtVCP / QtDragon_HD
OS: Raspberry Pi 5, Debian 12 (Bookworm)
LinuxCNC 2.9.6

What actually fixed it (short version)

Load the pendant HAL file as a HALFILE (before the post-GUI), same as the donor machine.
Add MDI_COMMAND lines under [HALUI] so pins halui.mdi-command-XX exist.
Keep qtvcp_postgui.hal clean (only GUI signals, no pendant driver).
In my case, moving the WHB USB dongle to another port made the wheel/jog and DRO updates work.

STEP 1 — Copy the pendant HAL file
Place xhc-whb04b-6.hal in your config folder (the same folder that has your .ini and main .hal), e.g.:

~/linuxcnc/configs/YOUR-MACHINE/xhc-whb04b-6.hal

STEP 2 — Load the pendant before the post-GUI
Open your .ini and in the [HAL] section add this line and keep this exact order:

[HAL]
HALUI = halui
HALFILE = CNC-CARPINTERA.hal
HALFILE = custom.hal
HALFILE = xhc-whb04b-6.hal ; <<< NEW: load the pendant here
POSTGUI_HALFILE = qtvcp_postgui.hal ; keep this AFTER
SHUTDOWN = shutdown.hal

Important: do not load the WHB driver inside qtvcp_postgui.hal.STEP 3 — Create MDI pins under [HALUI]
In the same .ini, find (or create) the [HALUI] section and paste this block right under it:

[HALUI]
MDI_COMMAND = (DEBUG,<1>) ; <<< NEW (good for testing macros)
MDI_COMMAND = G10 L20 P0 X[#<_x>/2.0] ; <<< NEW (zero X at part center)
MDI_COMMAND = G10 L20 P0 Y[#<_y>/2.0] ; <<< NEW (zero Y at part center)
MDI_COMMAND = (DEBUG,<4>) ; <<< NEW
MDI_COMMAND = (DEBUG,<5>) ; <<< NEW
MDI_COMMAND = G10 L20 P0 X0 ; <<< NEW (Zero X)
MDI_COMMAND = G10 L20 P0 Y0 ; <<< NEW (Zero Y)
MDI_COMMAND = G10 L20 P0 Z0 ; <<< NEW (Zero Z)

This creates halui.mdi-command-00..07 (indexes follow the order above).
Add more MDI_COMMAND lines if your xhc-whb04b-6.hal uses higher indices.Notes so jogging actually works

E-STOP released, Machine ON
Manual mode
Fully homed (for XYYZ: X, Y1, Y2, Z)
On the pendant, use Continuous, or Step + Step size
If the wheel does nothing or DRO does not update: try a different USB port/dongle (this was the final fix for me)

Thanks and request
Many thanks to the original thread’s author for sharing files and guidance.
If possible, could you post a short summary of the final button mapping (what each macro-N does, Continuous/Step, ABS/REL, etc.)? That would help beginners keep their configs consistent.If anyone needs it, I can share my final .ini, xhc-whb04b-6.hal, and a minimal qtvcp_postgui.hal exactly as they ended up.
