Microstepping

[clough42]

There likely isn't any advantage in terms of resolution, and 1/16 is pretty smooth with most steppers anyway.

Make sure you're using stepper motors with very low inductance if you're having trouble with noise and vibration. Inductance per coil should ideally be under 3uH for a 12V power supply. If your inductance is much more than that, you're probably already having trouble getting the current to rise fast enough in the coil to do 1/16 microsteps. This was a problem with motors that MakerFarm was shipping in early 2014, but I think the later motors are better.

I switched out all the motors I got from MakerFarm with NEMA 14's from your shop and my vibration/noise problem has gone away. Even the NEMA 14's that I bought from MakerFarm were giving me a lot of vibration.

I also have confront the s.imilar problem as you, but i have solved now. Thanks for your sharing
