The builder we have forked is based on Debian, not Rpi but we do fetch and build the Rpi  kernel from source.
That way you get the best of both worlds.
Linuxcnc is a Debian application so all the menu features are installed from Linuxcnc deb files.
Its not intended as a generic Rpi installation so it won't include any standard pi applications which could add additional latency.

Salve,
Thank you so much for this new resource. I think i'll start playing around with it as soon as i get a Raspberry Pi. i wonder what is the maximum control frequency using this solution.
I see you are a professor. I'm currently a computer engineering student at UniCal. i wish there would be a similar project at my university .
Hope you do well. Thanks again.

I have been retired for a couple of years now.
If you want, I can give you the name of a UniCal teacher who, in addition to knowing me personally, could answer your questions.
In the meantime, I'll see if I can find the digital copy of this thesis which could be a good starting point for your work.
 

Thanks for getting back to me.

I wanted to that that I got the image to burn onto a card through random internet searches / and re-try's. I'm sure we are all familiar with middle of the night stubbornness. LOL

Once burned the image seemed quite quite good to me with the caveat that my next step will be to get my 7i95T board configured so I haven't yet tested end-to operation.

I used saved versions of all the raspberypi.org and raspbian.org config files for apt including the keyring files that are needed. So it was quick to update/upgrade/apt install a reasonable collection of Pi specific config tools.

So thanks for making that image available.

I do have a few questions/hopes about embedding some of those tweaks into the Pi 4/5 specific IMG's.

1) Include the Pi specific APT/PGP files on the conditional build you are using for the Pi.

2) Include the core Pi executables as well with serious bonus points for adding those to the default app-lauch UI like is being done for LinuxCNC.

Those two things would substantially reduce the newbie headwinds for those that are either new or rusty on Linux.

Thanks so much for all your work!
