Re: Pixie 100 step and dir to analog board setup

Fixed! The Pixie works great. The basic problem was that during
tuning I had to turn the K parameters to very low values (Kp=2, Kd=13,
Ki-0). The speed reference mode works fine so the Yaskawa amp does
not need to be set up in torque mode. I even have Mach3 running the
motor through the Campbell break-out board. What a relief!
