My stepper motor step angle is 1.8 degrees, the subdivision is 10000, so what is the speed per minute?
You get 1.8 is the motor step angle, after subdividing 10000, you can only calculate the step angle after you have to subdivide, 1.8/10000=0.00018 degrees;
The speed needs to know how many pulses you send in a minute to know, for example, X pulses a minute, then you have to speed n=X/10000;
