Hi Matt, I wired that up for Seb one evening at his place while he was playing with some very short humans who seemed to require a lot of attention. I don't really understand what was going on there, so I worked on the mill. The encoder is just unpowered mechanical switches giving quadrature. I had to add pull-up resistors (well I think I pulled up - I know I added resistors) to get it to work. If I remember right, the encoder gives 50 cycles per rev instead of the more usual 100. It is not the greatest jog wheel ever. I don't recall which of the three pins is the common... I bet one could wire it correctly in three or fewer tries though.
