Yes, its made for the Pi 5. I did notice the file name  may not say this.

I got it finally working very well with very low latency on my RPI 5

How is that any different to the Linuxcnc image on the downloads page?
The builder that made it It gets the official Pi kernel code, applies the RT patch
Builds the lernel
Installs Debian and XFCE4
Install Linuxcnc from the repo at Linuxcnc.org
It should be quicker because it runs on a desktop PC and cross compiles for the Pi.

It takes some time on the RPI.

As I am writing this in Firefox on this machine, latency-histogram (was started befor starting Firefox!) is running and 17 glxgears.
To be honest, so far I am very happy with.

 

Attached please also find a somewhat "script" to build from scratch.

Ex corporate pc is cheaper, more powerful, easier to setup than either the 4 or 5.

I'm trying out a new touchscreen with LinuxCNC 2.91 on RaspberryPi today. 

The Touch Screen is recognized in Settings | Mouse and Touchpad; two instances of wch.cn TouchScreen, however touching the screen has no effect either on the desktop or from within Axis.

Do I need to enable a driver, or do something special to get this to work?
The keyboard, mouse etc are also recognized and they both seem to work just fine.
 

Was looking for info about raspberry, do you suggest to make a new buil on pi 4 because it's more stable? Or it's worth go with the 5?
