I should think that unless you are trying to go very fast there's no point in going more than 16 or 32 microstepping. You certainly I won't get better resolution.

I might be wrong, but doesn't increasing the number of microsteps decreases speed ? As I understand, a stepper will go 200 steps per revolution (generally, unless they're half steps or quarter steps), and the driver will use microsteps to make one stepper step. So, 128 microsteps means that the stepper will turn 1 physical step every time the driver makes 128 "electrical" steps. Therefore, increasing the number of microsteps without changing their frequency will increase the time per revolution, thus slowing down the machine.

Or am I way off the track here ?
