Linuxcnc 2.9.2 and 2.93 images for Raspberry Pi 4b & 5

Category: Installing LinuxCNC

First of all, thank you very much for your work with the images. 

According to everything I found on the net, a pi 5 8GB with SanDisk extreme pro 64gb, official power supply and a Mesa 7i96s should work without any problems? Is that correct?  

Are there any restrictions regarding
- user interface (probe basic, gmoccapy)
- the wireless 6 axis handwheel  

One last question about the cooling / housing.Is a passive cooled case like the Flirc Raspberry Pi 5 case sufficient or should active cooling be provided? My thoughts on this are mainly dust protection.


Perhaps useful for others
Unfortunately, the standard office monitors all have large ventilation slots on the back. I have been looking for alternatives for a time and would now like to use a mobile external monitor (sold as a supplement to the laptop). These seem to be much better protected against dust.

Thanks 
Erwin

8gb will be fine. 
Linuxcnc runs happilly in 4 gb on most platforms.

Category: Installing LinuxCNC

Hello gentlemen !

Im a Newby and want to run a CNC-mill with a Mesa 7i76E and a Rpi 5.
I have  read the thread and think a RPI 5  with 8 GB will be  the right choice for
bookworm and the mesa. The 16 GB RPI5  won't work or is there any kind of news ?
The freason for the question is that i have to buy a RPI but which one is the best opinion and why ?
Can you help me ?

Thanks   a lot

Category: Installing LinuxCNC

i was able to bench test the image with the ethercat master installed from the repositories and it works. The only thing i found peculiar was that when jogging with the keyboard i could notice some random jitter in the drive. This did not happen with the amd64 cpu i was using before. I suspect this could just be an issue with the keyboard input on the pi though as that jitter is not present with commands from the MDI

Hi
i think you didn't install the NVMPG component here

I thought it was optional.
Do I have to install all of these then?:

sudo halcompile --install ./Remora-eth/remora-eth-3.0.c
sudo halcompile --install ./Remora-spi/remora-spi.c
sudo halcompile --install ./Remora/remora_lpc.c
sudo halcompile --install ./NVMPG/nvmpg.c
sudo halcompile --install ./PIDcontroller/PIDcontroller.c
sudo halcompile --install ./PRUencoder/PRUencoder.c

I don't have a raspberry

Thank you so much for your precious help

LinuxCNC and Linux and Ubuntu and PC and RPi ping issues with Mesa 7i96s

Category: Installing LinuxCNC

No need for a base thread with an external motion controller.
I run mine with a NVMe drive, yeah boot is really fast, I've been playing a around with custom hardware and hostmot2 firmware over SPI. ATM I'm working on a ethernet board to replace the SPI\EPP board that mates with the fpga board I'm using.

If you could add your Etherent mods to the thread linked below it would be great, trying to have a one stop place for all issues/suggestions and such.

Category: Installing LinuxCNC

I think the raspberry pie five and Mesa set up is really quite brilliant. It’s very compact, and boots up really fast. The only negative i have found is that it’s difficult to put an external Wi-Fi antenna on the pie. If the pie is inside a metal box, it won’t connect easily to a Wi-Fi router. You can get around this by using an external Wi-Fi dongle. Or move the excess point and pie closer together.

Category: Installing LinuxCNC

The reason I was running that test was because packets were being lost between the raspberry pie and the Mesa board. I couldn’t figure out why. It was suggested to change a setting (I forget which one, but it is documented on The Forum) and after that there was zero packet loss.

Hallo PCW, 
ich habe noch einige andere Einstellungen versucht aber ohne Erfolg.
Eigentlich ist das Hobby fräsen und nicht Einstellungen in Linux CNC zu testen.
Deshalb habe ich überlegt einen Raspberry Pi 5 8gb zu kaufen. Jederzeit verfügbar, ein fertiges Image, kein raten / testen, passt bequem in den Schaltschrank. 

Hältst du das für sinnvoll?

Grüße Erwin

You'll have to give a description of your setup, what image are you using, what is the latency & ping times.

Hello, unfortunately I don't have a contribution to your CAM system, but I do have a question about the Raspberry Pi 5 and Linux CNC On the current PC I have problems with the latency, especially in the Ethernet connection to the 7i96s. Unfortunately, this always leads to unexpected stops of the machine. The last PC was no better and I don't want to buy a third one that will cause problems. My hope is that the Raspberry Pi 5 will work easily and without problems, even if it is a bit more expensive than a second-hand PC. Replacement would also be possible at any time. Now to the question What are your experiences with the pi 5 and which version are you using? Which SD card? Any special settings? Thank you very much Greetings Erwin

Developing a Raspberry Pi Pico-based I/O Board for LinuxCNC

Category: General LinuxCNC Questions

Dear Community,

I’m excited to share io-samurai, an open-source, budget-friendly interface for LinuxCNC and remote I/O projects, built from the ground up for makers like you! I’ve been working hard on this project, and I’m thrilled to announce that once the first batch of final PCBs arrives and I’ve thoroughly tested them, I’ll be releasing the full project on GitHub under the MIT License. Here’s a sneak peek at what’s coming:
What is io-samurai?
io-samurai is a versatile platform for CNC control and remote I/O, powered by Raspberry Pi Pico/Pico 2 and W5100S/W5500-Lite Ethernet modules. Key features:

    16 inputs (20–50 V, MCP23017, I2C) with Zener protection.
    8 high-current outputs (50 V, 500 mA, TD62783-driven, MCP23008-controlled).
    Single analog inputs (10 kΩ potentiometer, 0–3.3 V, GP26).
    40 MHz SPI (~6000 Hz burst) for fast Ethernet communication.
    Optional SH1106 OLED for I/O status and IP display.
    LinuxCNC uspace HAL driver (compiled with halcompile, .so), with safety features like timeout and data checks.
    Python library for automation and remote I/O.

It’s perfect for LinuxCNC users, but also great for IoT, home automation, or any project where you want to experiment with hardware and software.
Current Status
I’ve invested $268 into prototyping, and the first five final PCBs are on their way (~$40–50 each). Once the PCBs arrive and pass testing, I’ll publish the project on GitHub, including:

    Firmware: Pico/Pico 2 code with Wiznet’s ioLibrary_Driver (MIT licensed).
    HAL Driver: Uspace .so for LinuxCNC, with full setup guide.
    Hardware: Gerber files for PCB manufacturing (e.g., JLCPCB, PCBWay).
    Documentation: Detailed pinout.md, setup-guide.md, and io-samurai-manual.pdf.
    Python Library: For remote I/O and automation.

The GitHub repo (github.com/atrex66/io-samurai) is ready to go live under the MIT License, ensuring everyone can use, modify, and contribute to the project.
Get Involved!
I’m passionate about making io-samurai accessible to the LinuxCNC and maker communities. Here’s how you can join the journey:

    GitHub: Follow the repo for the upcoming release (github.com/atrex66/io-samurai).
    X: Follow updates and share your thoughts: @aTrEx77.

What’s Next?

    PCB Testing: Validate the final boards with W5500-Lite, MCP23017, MCP23008, and 10 kΩ potentiometer.
    GitHub Release: Share all code, docs, and Gerber files under MIT License.
    Roadmap: Mach3 driver, FPGA-based step generator, (~$150 full CNC or HMI control with display and pi Zero 2W).

I’d love to hear your feedback or ideas for io-samurai in LinuxCNC setups! What features would you like to see? Let’s build something awesome together. Built with ❤️ in Hungary.

Cheers,
Zsolt Viola

i think i finished the prototype stage, all of the prototype faults are corrected, pcb updated, Linuxcnc HAL Driver finished with safety mechanism (watchdog + jump code checksum, (also in the pico)), added optional lcd connector(128x64 sh1106) to the pcb, python library is ready for other uses (experimenting, remote io, etc....)

Mesa 7c81
Debian GNU/Linux 12 (bookworm) 6.1.54-rt15 #1_RT Fri Nov 17 17:02:27 AEST 2023 aarch64

I installed LinuxCNC 2.9.3 from the linuxcnc ISO image a couple of years ago, and upgraded to 2.9.4 yesterday by:
$ sudo apt update  && sudo apt full-upgrade

I now have:

Is there a newer RT kernel then the one from 2023 ?
If so, how can I upgrade the kernel without having to reload the entire system from the latest ISO image ?

TIA,
Rick
