Gene, sorry but I won't be heading that way! I did give Armbian a good go a few years ago but the board I chose just wasn't good enough for Linuxcnc. I do wonder if there is a viable case to adopt EVL .Recently I decided to build a small machine and I had a 15 year old PC which thought was old enough to have a parallel port but it didn't. I considered buying a card and a BOB, and also even a Chinese clone of the 7i92. But in the end, I bought a single 4 axis Lichuan ethercat drive for about $90 USD. Its hard to argue with that price! But now Robert has suggested making room for a new trajectory planner might redefine the thought process.
