LinuxCNC on Raspberry Pi 5

Also, for anyone wanting to use a touchscreen with Pi5, know that the on screen keyboards seem to be completely unusable at the moment.

Update:
Switching to X11 works MUCH better for Axis, but it still doesn't understand multitouch in the Axis preview.
Switching to X11 can be done by
1.    Advanced => X11
2. I had to install the gldriver from here to get X11 to show output:  askubuntu.com/questions/1501903/x11-sess...10-on-raspberry-pi-5

This also seems to have fixed the issues with the on-screen keyboard (onboard).
At this point it is a fully functional system, with some minor annoyances with navigating the preview window. 
I will make a patch for Axis to try and address some of the touch bugs.

First of all thanks for the great work. 

is it just me or is the link on the website wrong?
www.linuxcnc.org/iso/rpi-5-debian-bookwo...23-11-17-1520.img.xz
it say: LinuxCNC 2.9.2
but when I start it it say 2.9.1 

I thought I had an older one so I reinstalled today and still the same. 
Can I upgrade linuxCNC and GMOCCAPY?
i had some issues with GMOCCAPY now compared to when I was running the PI4 that I installed years ago.
One issue I had was when I pressed the aport button during a probing script, it did not stop but the GUI changed. 
I will try to reproduce. 
I copied my old config. Can that be the issue? I thought you could

Thanks all

Hey,elovalvo,I've installed your image in my rasppi5 machine,but met a problem while I installed the linuxcnc-ethercat ,I cant run "sudo apt install -y linux-headers-$(uname -r) ethercat-master linuxcnc-ethercat",because I cant find the right kernel version of header,could you offered that ? Thank you

if you are using the image from this link

forum.linuxcnc.org/9-installing-linuxcnc...pi-5?start=40#303752

maybe they should already be installed.

I've never used Ethercat so I've never had this problem.

However you can see at this link
linuxconfig.org/how-to-install-linux-ker...ders-on-raspberry-pi

Thank you so much ,that's very helpful.

Hi One problem solved and one remain ,I replaced the analog optical sensor to a "digital" one and the revolution meter start to work . the reading is ok and the reading is controled with a speedometer. the other problem is the red and green LED weryfing to start the process from the G-code program  G97 S600 M3 The program start at 150 rpm and the red LED starts at 350 rev, it is mirror action , it should start at ca 450 and stopp at ca 700 revs ,it is programd with 150 % tolerans .  

Maybe it's useful info ...
i had to power the RPI5 using a normal 5V/10A DIN power supply. Manage to do it and keep 4.7V at 3.1 A , enough for RPI to avoid detection of an undervoltage condition.
But then I was curios about the official RPI power supply ... and I have tested it with an electronic load: I've got the same voltage ( around 5.14V) from 0.5A up to 5.9 A .. at 6A it shuts itself down nice and safely ).
I think the official power supply is dinamically compensating the cable impedance by increasing the output voltage from the regulator based on measured current .
So if you need 5A , be very careful with the cable or just use the official power  supply , if possible ...
All of these where done with PD disabled ( a small USB-C breakout board with 5.11kohm on CC lines)

Hi everyone!

i'm quite new to linuxcnc and have some basic knowledge about linux, i don't want to compile a kernel and that stuff, installing specific packages are nit a problem...

at the moment i'm using a raspi 5 image from linuxcnc download page.
I have some resolution problems with my 7" touchpad, it loads the one and only available resolution 1920x...
i would like to have another resolution, my problem is that the "normal" things for raspi do not worl with debian image.

2 Questions:
- how do i do that with the linuxcnc debian image ?
- should i switch to the image provided here with raspios ?

i'm using the raspi together witth mesa ethernet card

thanks a lot

Lars

In a terminal, what does
xrandr
Return for available resolutions?
