My take on microstepping is that it's fine and dandy so long as there is no load on the motor.

As you go beyond half step it gets springy. Any stiction means it won't start to move until you're far enough ahead to overcome it, then, suddenly, BOING.

I half step to 10um then add an intermediate 5um microstep but it's only there to smooth things out, it ain't gonna happen :heehee:
