I am trying to turn something with a stepper motor very quickly, but have it end up in a very precise spot. I would like to use full stepping to get a lot of torque so it can accelerate quickly, and when it gets close to where it needs to be, switch to microstepping so I can position it precisely.
What type of driver should I look into for this? How quickly can I switch between full and microstepping? Do I need to bring the motor to a complete stop before I switch?
