    Dear Openbuilders, I have a pan tilt head with two nema 17 stepper motors. I like to use them for a differnt porpous. Unfortuntaly they don’t have amps or step° printed on them. The stepper has four cables: A-,A+B-B+. The manual for the pan tilt head gives the motor specs as following:

    Accuracy: 0.0025°
    Motor Power 8-32W
    Operating Voltage 14.8-24V
    Best Load 4kg
    Max Load 8Kg

    So am I correct in proceeding as if the stepper has a 1.333A max rating (32W/24V)?
    Also the accurcy throws me. Assuming there is microsteping factored in. How much steps/rev would that be?
