Nema 17 stepper motor problem

Questions

Hi, I’m currently completing my first arduino project which involves using stepper motors with an L298 motor driver and an arduino uno board.

I’m using the example arduino code for the stepper motors but, for some reason my motor only rotates about 20° using the default code. If I change the rpm or steps per revolution it doesn’t move at all and only vibrates.
