Looks like I am bit in the past. I found my old raspberry.
Is there any recent downloadable sdcard image to try on my RPI21? The one I found is from 2013. I would like to try it out and wonder if anything got better since then, if not it would be nice to have newer LinuxCNC and a working environment for compilation without all the trouble.
Is the new awaited RPI-compatible MESA board going to work with older models? It looks very promising!
I have a RPi3B+ running ith linuxcnc and steppers on GPIO, I used the instruction in the wiki to build it. Not the fastest, but it moves a simple mill. I'll get a mesa7i90HD next week, i'm couriouse how this will turn out.
The Pi3 in my 3D printer is still running flawless, and due to the fact that 3D-printing is a slow process it makes far, far more hours than mill and lathe combined.
The only issue I have is that the preprocessing of RepRap-flavour Gcode to LinuxCNC NGC is a bit slow for large files. I could move that to the PC running the slicer but I never bothered.
I have a newer image that is stable (been up nearly a year 24/7) with an RPI3 and a 7C80, 7C81 or 7I90, but I dont know if it will work on a RPI2 (is the SPI interface identical?, that is will hm2_rpspi work on a RPI2? )
