I am driving 2 different gears with a belt off of a stepper motor that has a step angle of 0.018 degrees. For the purpose of my project, I need to have high precision between the stepper motor and the gears that it's driving. Is it necessary to have 20,000 teeth (360/0.018) on the gear that's being driven in order to keep the same size steps from the motor to the gear? I am an electrical engineering student so I have no experience with gears so I'm not sure if a step will be lost if there aren't enough teeth to catch the small movements. I went with a belt instead of a gear train because I feel like that would preserve the precision better and to keep the mechanical portion relatively simple but if not, feel free to offer any suggestions.
