Hi Can anyone give me some advice. I have purchased a driver board which allows the maximum current to be set for each stepper motor, the permissable values are 1, 1.5,2 and 2.5 amps, My motors have a rated current of 1.4 amps (4.34 volts) for bipolar parallel and 0.7 amps (8.68 volts) for bi polar series. My question is, should I be setting the current below the rated current of the motors or just above ?

Many thanks
