Hello I have a arduino mega that’s hooked and running 7 ddrv8825 drivers and 7 nema motors that have 1.7amps rating I was wonder what type of power supply do you guys recommend? Also the way it works is one nema motor turns then stops then another turns then the first one turns again then another mo…

Power supply help please

jremington:
I second 3 amps at 24v.

You will get faster stepper motor response from the higher voltage power supply.

So I’d only need say 3amps with 24v to run all 7 motors?
