I'll add a less technical Issue that often comes up when NOT
microstepping. With Larger motors, "Full Stepping", even 1/2 and 1/4
stepping can introduce much literal noise, especially when more than one
axis is moving at lower speeds. It can be very annoying even for the
neighbors depending on your machine.

At some speeds, It might sound like you are being shot at by a rapid
fire machine gun. On the other end of the spectrum, "10 stepping" or
above (some drives can exceed 50,000 steps per motor step) with the same
motors often will sound like a fine symphony of violins !

I enjoy the symphony much more than I do being shot at !

If the stepper motor moves for example, 1.8 deg/pulse (step) for each pulse (step) put out from the PC parallel port how does the motor move 1/2 or 1/4 or 1/8 steps? Or does it move 2, 4, or 8 steps? Or is the controller able to manipulate the motor windings to get multiple steps OR partial steps for each step output by the PC? Then how is the above effected by parallel/series windings connection?
