Does the existing driver work? linuxcnc.org/docs/stable/html/drivers/hal_gpio.html

If not it will be up to the developers to implement something. Not something I do.

Would it be possible to provide an image for the functional Rasberry Pi 5 configured to access the GPIO?

looks promissing, will wait for the real, i will build those to change my old chinese bob, can we add axis to multiple z axis?i have plant to add my machine with diode laser and plasma cut

I've added a section to the documentation on how to get LinuxCNC and install LitexCNC:
litex-cnc.readthedocs.io/en/latest/raspberrypi.html

It is still work in progress, as I have only covered the PREEMPT image from LinuxCNC and I also want to add support for RTAI (using Raspbian) and older version (2.8.2 on buster).

The main reason for covering the RTAI version is personal: I just don't like the GUI from Xfce, and do prefer the GUI provided by the Raspberry Pi foundation.

I have built vtk from source on a Pi a long time ago (5 hour build) and it worked with PB
But there is no need to do that as vtk is now supported for ARM64 (raspberry pi 4/5) in the Debian  repositories
try; sudo apt install vtk9
you may also need python3-vtk9

There should be no reason why the qtpyvcp team can't build a pi compatible deb and host it on their repository.

EDIT: if you do that, pleas elet me know and I will include the qtpyvcp repo in the 2.9.2 installers

Hi Chris,

I heard there's been a lot of development on Probe_Basic recently and some new contributors.

Thanks for the fantastic work everyone !!!

Question; We currently have two CNC routers running Probe_Basic on Debian 10 and Mesa cards. We're trying to build a new Probe_Basic controller using a Raspberry Pi 4 and the BTT SKR v1.4 Turbo board. Do you know if the instructions above will work for that situation ?

rpi does not support the vtk used with qtpyvcp and is not supported. some have tried but i have not seen a successful implementation to date that i am aware of, if someone has done it maybe they can chime in?

Installed on a Pi5 8Gb.
Running great with a Mesa 7i76e

i hope this thing works

Aah, now I know what you were looking at. an XFCE feature

That's normal behaviour for the bottom panel in Debian for  XFCE (for amd64 & arm64) when you move the mouse over the area where the panel would be no matter the application you are using, if you right click on the panel you can change the properties. Not a bug & does not require reporting.

That is nothing to do with the installation process. I can't help. Report in the correct GUI section

One note--lcec_generic has a test that floats aren't larger than 32 bits. I've disabled that if we're using a double, but there's a chance that something under the hood will break. Again, testing.

It'd be kind of nice to have an EtherCAT test slave that runs on a Raspberry Pi (or similar) that we could use for testing this sort of thing. Then I could work it into my usual testing process.

Please use Balena Etcher to install the image in this thread rpi-imager does not work
forum.linuxcnc.org/9-installing-linuxcnc...pberry-pi-4-5-images
i think we are good with the Pi 5 now except for sound. If anybody knows their way around kernel settings for sound, please let us know


 

Scott,
Please read the Linuxcnc downloads page.
Typing: sudo menu-config
allows you to set wifi and locale etc.

Configuring fixed ip address etc for ethernet card, can be done manually as described if you type: man hm2_eth

We removed networkmanger I had added it in and latency suffered on the pi4b

If you really need to use it, you can install synaptics: sudo apt install synaptic 
I prefer to search for the package names in Debian Package search packages.debian.org/index
and use sudo apt install package-name

When you say you don't have sound, this is  a known issue, one of the upstream guys was going to review that for me as its a limitation of their installer. Their first priority was to fix the compression settings so it can be installed with rpi-imager.

I don't think it will be wise to use sudo apt upgrade becasue we have a custom built PREEMPT_RT kernel we have built from source using a kernel version not in Debian Bookworm..

Note the ethercat repos are installed if you want to go that way.
