I can't answer your question directly, but last night I was working to do the same thing and got it to work!
I did notice the same behavior, moving to the proper X and never starting. For me the problem was that I was using both phases A and B, and that the encoder was counting down, not up. Reversing A and B fixed the problem. Maybe this will help you too. -Kip On Mon, Nov 11, 2013 at 6:35 AM, Viesturs Lācis <viesturs.la...@gmail.com>wrote: > Hello! > > I am trying to help a guy that has retrofitted a lathe to LinuxCNC. > He has 5i25 + 7i77 cards and 2.5.0 version installed. > > The problem is that I cannot figure out, how to get threading to work.
