I think partly I don't understand the difference between the current LinuxCNC and the MachineKit LinuxCNC. What does make them so different that a newer version of LinuxCNC with bugs removed can't be used? Since the Beagle has an Ethernet port could I use it to run the MESA? Or does that once again require long strings of LinuxOS upgrade knowledge since the for LinuxCNC need a precompiled (for BBB) hostmot2 driver?

loadrt hostmot2
loadrt hm2_eth board_ip="192.168.1.121" config=" num_encoders=0 num_pwmgens=0 num_stepgens=5" setp hm2_7i92.0.watchdog.timeout_ns 5000000
etc...

Again, thanks for your very thoughtful reply.

LinuxCNC should run a Ethernet connected interface on a BBB without any changes, It may be that a buildbot ARMHF image will work (so you dont need to build LinuxCNC) but I dont know if it has been tried.

Theoretically the PRU support could be ported to LinuxCNC, I think that would be a good thing.
