I got my SmoothStepper and got it running in no time. It is going to make a huge speed difference on my router. I also had a servo motor that was very flakey on the parallel port, but works perfectly on the SS.
Here are my first issues.
1. The motor tuning screen does not work interactely anymore. I can change the settings, but the only way to move the motors is to save the settingas and close the screen. Not a show stopper, but it takes a lot longer to tune the motors.
2. I can't get my Shuttle Pro to work. Some of the buttons work, but the jog dials don't. It will be a drag until this is figured out.
3. Sometimes the DROs won't zero when clicked.
