over on the forum there is this link http://linuxcnc.mah.priv.at/rpi/rpi-rtperf.html the educated guess on IRC yesterday was that the Pi might be able to run linuxcnc motion with a 1ms servo-thread and a lightweight GUI. Software step-generation is probably too demanding. I'd like to run these latency-tests myself when I get my hands on a Pi. Preferably with hardware in the loop, i.e. actually output pulses at 1ms and use external hardware to check that the 1ms timing is OK.
