Hi,

Ballendo, nice explaination. I would like to expand a little on it
though.

You can think of a full-step sequence as one extreme
of "microstepping" while a pure sine-cosine current would be the
other extreme, having infinite resolution.

From this perspective full stepping is simply a single-bit
approximation of a sine-cosine, carrying only sign (+/-) info.

Half-stepping has about a 2 bit resolution, "microstepping" proper
has progressively more bits of sine-cosine approximation.

The main advantages are: (1) increased accurate resolution up to 10
microsteps (motor accuracy limit at about 1 part out of 2,000) and
(2) low speed smoothness because of less ringing.

Running torque is not adversely affected though holding torque is.
This can be a red herring. The moment a full step driven motor begins
to turn, it losses 35% of its torque to ringing.
