M350 X256 Y256 Z256 I0 ; Configure microstepping without interpolation
M350 E16:16 I1 ; Configure microstepping with interpolation
M92 X1280 Y1280 Z6400 E415:415 ; Set steps per mm

I suggest using 16 microsteps interpolated to 256 to start with and calculate your steps per mm to suit that. Afterwards when everything is working you can experiment with different microstepping settings.

This document should help get you started on commisioning your printer.
