I am running it quite well on the the r-pi-3b's, newer single spi interface on 3/4 ton of old Sheldon lathe. I say newer because the hm2_rpspi.so driver I am running has grown some additional legs by Bertho S. and was just accepted into master. It (the raspi-3b) is kernel picky though, bad keyboard and mouse missfires with the newer kernels like the 4.9.x. from Frank Durr. 4.4.4-rt9-v7+ is working the best here ATM. With a Mesa 7i90 in the bottom of the pile, and 3 7i42TA's on top for surge suppression and noise filtering to protect the 3.3 volt 7i90, not to mention giving us a decent place to terminate all the wires, I seem to be ready to rock & roll. I am collecting tooling, and considering a 4 jaw chuck, and I've already made some of its parts to cnc it, on it. I have the 3 jaw within about 1.5 thou of true, lots better than it was when we horsed it out of the cargo van here a year ago.
