gary wrote:Harry, I should just emphasise, in case there is any confusion, that it is not driving the stepper harder (with voltage or current) that causes it to go faster - it is overcoming the tendency of the winding inductance to impede current flow (rise time = L/Rw) by increasing the circuit resistance (rise time = L/(Rw + Rlimiter).
Anyway, I am trying to not be too technical, but a good analysis can be found here:

By the way, the X is just the letter X, not 10 lol.

How 'true' does the unsupported outer edge of the drum run when up to speed?
Does spinning it essentially get rid of wobble?
