I do not see Images for LinuxCNC 2.9.3 on the Download page, am I blind?
With the ones provided I ended up in 640x480 display resolution, no idea why. But I could not use it.

To me, this is a big difference.

btw. build time is no issue on the RPI5.

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.

thanks a lot! can that image used on an raspi 5?
