I can't cos I don't have a pi.  But do this:
Download the iamge
Burn do a SD card using  Balena Etcher (free download windows and linux)
Boot the pi using the SD card
Log in with username/password cnc/cnc
open a terminal
type: sudo menu-config
and set up your wifi if required, locale and time zone etc. You can also change your password.

After that you have a computer with linuxcnc installed so simply refer to the docs on the LinuxCNC web site. There is a specific gpio driver for the Pi that is documented there. There is also a pi specific Mesa card but I would recommend you use a Mesa Ethernet card for future flexibility.

You can also install ethercat if you want to use it but thats not a beginners path
sudo apt install linuxcnc-ethercat (from memory)

Hello.
Sorry that I'm asking 2nd time, but...
How can I change the resolution, orientation (+touch) and make it sound?
I have a 10.1" IPS Touch display with resolution 1920x1200 @60 Hz + audio speakers.
But there is no sound, the resolution is only 1920x1080, no possibility to rotate the screen.
Is it possible to make it work?
On a Windows system the display works fine. (even tried on the Orange Pi PC with Armbian and it almost worked)

My config.txt file
arm_64bit=1
initramfs initrd.gz followkernel

Could anyone help, I made the image for the pi4 following the image on the official page, but it doesn't have the area for ethernet configuration, how can I solve this problem?

The current 2.9.2 image  needs updating to 2.9.3 but we no longer install Ethercat repositories for the Raspberry pi.
I am not sure if the pi is supported in their repos for Debian 12 at all
Also I doubt that a linuxcnc-ethercat driver is built for the pi either
Right now your option is to build from source
I have raised an issue with Ethercat to explore a solution for this.

In my case, it would be ethernet, I need the configuration area for the IP/Gateway address, that way, I can study the connection with ethernet cards.

The first post has been updated to include images for 2.9.3.
The Pi 5 is tested and working.
Any feedback about the Pi4 would be appreciated
