Ok I am trying to buy one of these. I hooked up my driver + stepper + arduino to a breadboard for testing and I used two 9V batteries in series to try and test it but it didn't work, not even made a sound. I know using 9V batteries isn't good cause they won't last long but I figured it would at least work for testing, think something is wrong with my wiring or just test with a real power supply?
Very cool man, I am looking to do something similar. What power supply did you use for the steppers? I am new to this so any advice / direction is appreciated. Cheers!
