Hi, One of the advantages of Geckodrives over other drives is that they morph from microstepping to full stepping after the speed gets above a a few RPS.
That way, at low speed you get very smooth motion, and at high speed the=re is no torque lose due to microstepping. BTW, microstepping does not combat resonance, specific functionality in the stepper drive is need to address it which all Geckodrives have.
