What kind of power supply

does anybody know how many volts and amps my power supply would need to be for 4 nema 17 motors rated at 2.4v and 1.5 amps per phase? i am also using a cnc ahield with drv8825 drivers. i am currently using a 24v 5 amp power supply. also when reading the voltage from the driver with a multimeter it reads 24v and i cannot lower it when turning the screw on the 8825. can somebody help me please.

Hello.

That power supply should be able to provide enough power. It sounds like you might be trying to set the current limit on the driver. Where are you placing the multimeter probes to measure the voltage? Have you seen our video instructions for setting the current limit?
