I remember when I first read about the stepper motor. Sounded then like a perfect idea, and still today! Not sure why they could not get the motor to work? As far as saying the stepper is not fast... you just need to change the spec and go to a higher voltage motor. I wish someone would try that again as I think it could really be made to work. We did something similar to that with a cold gas system on big, big rockets. Granted, the motors were probably a tad bit more expensive, but still, it should work just fine. You don't have to react to the millisecond over/underruns. If you look at how Bosch is doing their control loop, they have less than 60 hertz on some of the fancy sensors, and about 2 hertz on some others. This ain't rocket science
