I did exactly that with a BBB and Xylotex cape, using one of the unused limit inputs for a single pulse per rev sensor. You might want to follow the discussion on https://groups.google.com/forum/#!topic/machinekit/RW_bnXdXzyE (you'll have to read up to the end). You need a little familiarity with redirecting the input pins of the BBB to the hardware encoder (eqep) on the BBB processor, and in case of the Xylotex cape, I had to remove the large capacitor of the input RC-circuit because it smears out the pulses too much. The eqep encoders are fully supported in the present machinekit images for BBB. I did successfully manage to do threading on a small lathe with that contraption. Cheers, Karl
