I don't know if that's a good candidate to test LCNC.
I wouldn�t expect the 3B to work with Mesa Ethernet as the pre-4 Pis have the
Ethernet in the USB bus.
I've also read that the Pi4 8GB is not ideal for LinuxCNC. Apparently it has
issues with that much memory on the Pi. It works best with 4GB apparently.

Huh? That makes no sense. If nothing else, you can use it for fake swap
if nothing else.
RPi is NOT good for any industrial use. This thing is for kids to learn
Linux and open source programming techniques. RaspberryPi PCB design is
just bad for industrial use: holes for mounting, using glue for CPU
heatsink, connectors positions and their orientation, sandwich style
header connector for DIO, silicon waste (for sound and video IO), etc.
To execute G-code using a large footprint computer makes no sense
anymore. This open source based solution is gaining popularity for
simple CNC:
https://openbuildspartstore.com/interface/ and other related HW.
Just the fact that Openbuilds is not using LinuxCNC is saying something.
Dead end: no innovations, limitation in electronics/hardware selection.
