A Raspberry-Pi is MORE than capable of handling the real-time aspects of CNC control - FAR more so than an Arduino.
Interesting. I am certainly not going to contradict you - I am not really surprised to hear it.
However it is not a message that is widely available on this Forum - perhaps we are too short-sighted.
Its a pity I can't do the same stuff as the RPi on my laptop.
