Ok have a couple of questions how many power supplies will i need for this set up 3 nema 23 steppers at 3.6V/Phase 2.4A/phase.
2. each motor has its own driver board that i got from pminmo the http://pminmo.com/forsale/1X279805.pdf
I think you could use 1 (24v) 6amp power supply (shared between 3 boards.
Or you could use 3 (24v) 2amp power supplies (one for each board)
Just make sure you don't exceed the maximum voltage the boards can handle and make sure the power supply/supplies can supply enough amps.
Feel free to correct me if this is wrong.
