Update LinuxCNC 2.9.5 on debian 13

Category: Installing LinuxCNC

That's ok mate.

What I found with the RPi Dbeian kernel is that it didn't allow for overlays, so things like SPI were an issue. There's quite a few customisations for the RPi compared to a "vanilla kernel".

The official image, which gives an easy way to start for most users, uses a kernel built from the RPi github sources and configured for real time. It took a bit of time to find the "right kernel" from their sources, but eventually it was found and the image was an easy task from there on in.
There's quite a large thread with the first post explaining what it's all about. And as ssh is enabled out of the box you technically don't have to connect a keyboard and Display.

Yeah, no love. I'm going to go with QTDragon instead.

I'm sorry if that came out sounding arrogant, that was not the intent. I totally understand why Tommy suggested apt update, I just wanted to quite literally save his and my time.

I can certainly build it myself, or use 2.9.4 that works just fine for my purposes, or whatever. I don't have a problem, LinuxCNC has a problem, and being unable to fix it for everybody, I'm reporting it here in hopes that someone blessed with permissions does that.

Raspberry Pi OS Lite doesn't come with a desktop environment or a window server pre-installed, so I'm free to choose what to use (XFCE obviously lol). PREEMPT_RT kernel is available as an official package from Raspberry Pi debian repos these days and works fine. I'm not sure what the "official" linuxcnc raspberry pi image would give me at this point, and it is much harder to use for me personally - it requires me to connect a display/keyboard, for example. As to libgpiod or axis, I don't use either so I can't say anything about them.

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.

Seems a bit over the hedge, i mentioned multiple times that for under 100$ it is very OK, but 279$ i can not justify nor advise any longer.

I've done that, quite obviously. I think it is better to save time and skip obvious advices, I have 20 years of in-depth professional experience with Linux behind my back.

The real issue is that the package depends on the version of python3 that trixie doesn't provide, as can be seen here :
Depends: python3 (<< 3.12), python3 (>= 3.11~),

amd64 package depends on 3.13 :
Depends: python3 (<< 3.14), python3 (>= 3.13~),

It looks like a simple oversight more than anything else, those things happen. If it is, I hope it gets corrected soon!

What Linux OS being used including kernel type?
Debian 12
-  What version of Linuxcnc is installed?
2.9.4

-  What version of QtPyVCP and Probe Basic is installed?
Version from here: kcjengr.github.io/probe_basic/quick_star...l#installation-steps

-  How did you install Probe Basic? Quickstart guide? Dev Guide? 
I followed the quickstart guide.

I get an error when I run the third command 'sudo dpkg -i python3-qtpyvcp_5.0.2-19.dev_amd64.deb'
The download folder shows the file.

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.

Waveshare do an add ethernet adaptor that connects via the pcie bus, they also do one that has a Nvme drive and an ethernet adaptor.
The Odroids have Realtek adapters, so there's that to think about, but I didn't have any issues although I did install the dkms drivers. Then again the Odroid has Nvme and sata ports built in, so no extra $$$ in that respect.
The N100 with Intel hardware sounds like worthy advice. Decisions decisions.

Is there a new Linuxcnc release in the wings ?

Category: General LinuxCNC Questions

Everything has been pretty well documented within the package lists and in the commit messages.

I thought a backport would be a package that is in eg Trixie that was been repackaged for Bookworm.

TBH the extra packages may be pulling in too much extra stuff, the ISO weighs in at about 4.1G, which I think is due to suggested packages being installed as well. And TBH I've only included them to make transferring files around a little easier whilst testing. Like I said it's experimentation ATM, whether it's any use upstream I don't know.

Not even going to bother to upload to Google drive and ask for any help testing as it was a waste of time. I guess people are busy.
