So it may be just either friction from the motor or inertial load or time it takes for the current to build up in the coils (higher voltage may help there). > > >> > Slow down = limit your maximum speed (which is really just a crude, >> simple way of limiting acceleration, which is what you're actually after). >> >> > > Well, it seems that with a microstep resolution of 1/8, that maximum speed > limit is 40. > Side note: "40" is an arbitrary number unless you specify your time-base, the steps/rev and microstepping settings.
