your progress is awesome, im a newbie in that topic.
i've tried the machinekit distro from http://orange-cnc.ru/ its in russian by default so i had to change language first to try.
could you guys make a flashable IMG for the OrangePI ONE, im trying to implement a new CNC machine. The image form the russian webpage has very bad latency results. there is something written about a coprocessor that supports good stepping pulses but i dont understand whats ment. :)
i'm looking forward to use linuxcnc, because i think its just much better than MACH3. cheers
