LinuxCNC on RPI

Great work! Thank you!

We will work on getting the latest 3D graphics drivers and getting a Gentoo ISO going with latest Linuxcnc for the pi4.

Maybe someone else can work on Debian/Raspian packages for this.

I made an SD card image:

www.linuxcnc.org/dists/buster/2.8-uspace/

It's a run-in-place image, I couldn't figure out the packaging for Raspbian. This means you have to use

. ./linuxcnc-dev/scripts/rip-environment
linuxcnc

to start it. But then it works.

We worked with the pi 3 and 4 a bit and stopped development. The HDMI was too flaky for 4K output. Not sure if we will ever return to using them.

I don't think a CNC machine needs 4k, though.

I do for some of mine so we end up having to support too many different boards. Maybe the Rock64 or Odroid quad core + mali or similar board that does a good job of having ports that conform to spec (SATA, PCIe, HDMI etc) vs more Broadcom junk.

Heatsink definitely required for the pi4.

Very Cool, Scott. Will be very interested to see the code once released.
