Increasing microstep number also increases RPM and number of degrees about stepperdriver HOT 2 CLOSED

Have you observed a different motor speed after changing the microsteps ? If so, then the microstep didn't get set correctly, check the wiring to M0-M1-M2 or try a different microstep.

The RPM should not change at all. If you are referring to this line in the example, please note that move() needs a step adjustment because it counts actual pulses, so when in microstepping mode the number of steps needs to change.

The number of degrees in rotate() does not need to change at all: rotate(-180), rotate(180).
