Well it's hard to get people to see potential in something until it already exists in a useable form. I'd have already started writing the code if that was my thing but it's not. Coding for LinuxCNC is kind of obscure, I've worked with a friend on some LinuxCNC geared code but by the end I felt like I was pulling his teeth.

Personally I see the Teensy as a platform that would be good for a modular firmware. Mesa's HM2 is designed this way. The quality of the IO board is a moot point if the person writing the code didn't spend a lick of time on that specific PCB, they just wrote targeted software for the Teensy with the stepgen, encoders, as modules with some easily editable portion that resembles a "bitfile". I probably said all of that already but I do stand behind how useful that would be and the Teensy 4.x being the right platform for it.

You mention Machinekit, which I'll agree as I was never fond of BBB's. One lesser known thing MK did that could have been extremely useful was MKSOCFPGA. They ported HM2 to Altera for a DExx Nano. It basically treated the FPGA side as a Mesa 5i25 and all you had to do was modify a bitfile to give the pins any purpose they needed. The 2 problems that messed this up is the CPU in the Altera SOC was weak with no GPU at all, and this was not a thing that was supported in LCNC at all and MK was pretty much dead by the time I started looking at it.

I reached out to someone who definitely knows what they're doing but probably has no interest in this. I think if this got kicked off in a meaningful way it'd be pretty well adopted. It it's only seen as a cheapskate solution or a replacement for Mesa hardware in general it won't go anywhere because neither of those are good use cases.

Another similar multiple board solution: forum.linuxcnc.org/18-computer/44828-rem...ernet-nvem-cnc-board

I still lean towards a single board computer solution where all you need is some IO protection and level shifting.
