There's been on-and-off discussion on these lists over the years about combining a LinuxCNC controller on one board with an X11 server on a separate one. The same thought carries over seamlessly to the current discussion of ARM-based implementations. My usual answer is "just do it!" My personal taste runs toward strapping a small board on the back of a monitor to create what used to be called an "X-Terminal" 20 years ago (when the price of a single workstation was ca USD10000) but to each his own. Why not just use two Beaglebone Blacks communicating over ethernet? The total cost of ownership isn't so very different even considering the cost of an ethernet switch. I ceratinly wouldn't waste any time futzing with ethernet-over-USB. Regards, Kent PS - as for the X loading on the Beaglebone Black, I posted some of my early measurements at https://sites.google.com/site/manisbutareed/beaglebone-black-linuxcnc . I meant to do more but a personal tragedy disrupted my plans and I never got back to the subject. ------------------------------------------------------------------------------ DreamFactory - Open Source REST & JSON Services for HTML5 & Native Apps OAuth, Users, Roles, SQL, NoSQL, BLOB Storage and External API Access Free app hosting.
