Primarily, the main function of microstepping is to help motors turn smoothly at low speeds.
If you want to read about various aspects of stepper drivers, and have several hours to spare, search out the many posts by Mariss Freimanis over on CNC Zone, particuarily in the Gecko Drive and Stepper Motor forums. Mariss is the brains behind Gecko Drives, so knows quite a bit about them!


Forgot to mention, keep us updated about the build/conversion!
I'm considering a SX2 once funds allow, as it's about the ideal size for some parts I'm thinking about making/selling.
