Driving stepper motors smoothly?

    First of all, what is the appropriate newsgroup for questions about
    stepper motors? On with the actual question:

    Is there a reasonably priced option for driving stepper motors
    smoothly, i.e., not having them stop and start every 1.8 (or 0.9)
    degrees? I have some 200 step/rev motors that I would like to drive
    at speeds ranging from 0.1 to 4 RPM in one application and 0.4 to 16
    RPM in another. I would prefer a system that has already been
    designed by someone who knows what they are doing, though I would not
    mind doing some kit assembly.
     
  2. I like Ocean Controls stuff. It's attractively priced, it comes with
    nice graphic control software for a PC. It's an Aussie shop.
    They know what they are doing. Take a look

    [There are plenty of others....]

    I would say you don't fill an intending helper with confidence if you
    can specify max and min rates, step size but not power requirement. or
    torque or some such....
