Thank you for your hint. Sorry, no mesas in my shop, but at least I have some encoders waiting :-) Ages ago I had a single RPi2 (the newer ones) running with linuxcnc + TDE and GPIO for signals, just like the parallelport. Latency was not so great (~ 20000ns), but at least the steppers turned. Last week I wanted to resurrect the project, just finding the RPi beeing unable to boot. Well, following your hints I came to the conclusion that almost anything is better than a RPi for CNC (oh my, never thought I would write that). Now I've placed a T60 mainboard into a 15.4" T61p with libreboot (stock bios gives horrible latency) + linuxcnc + TDE + NativeCAM, looks neat and has nice latency (<2000ns).
