Stepper Motor Voltage?

[cabal2000]

Presently running a Maestro on 12 volts. Looking to replace the present 1.8 degree stepper motors with 0.9 degree motors. I do know that the board does have a max amp current of 1.68amps. What should I be looking for when it comes to voltage? There are so many different stepper motors voltages to choose from.

Thanks guys

@cabal2000 the general rule is "as low as possible". The more voltage the stepper motor needs, the lower the speed at which the driver is no longer able to supply sufficient voltage. See https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors.

@dc42 Thanks brother!!
