Stepper voltage

RE: Stepper voltage
Please google "stepper motors" to read on how these steppers are working.
But in short, what's important for steppers is the current limitation. The operating voltage can be increased by a factor of up to 8 or 10 (depending on the model) and that will increase the max RPMs but the max current per phase (1 coil) has to respected to prevent overheating/destruction of the stepper. The stepper is driven by a driver ( Pololu A4988 - https://www.pololu.com/product/1182 ) . Have a look at the Current Limitation paragraph that should help you to understand. So, when you first power up your robot, you need to adjust the current on the Pololu.
