hello, i just got a big easy driver stepper motor driver from SparkFun. I wanted my stepper to run a little smoother than it did with an h-bridge and plus i fried the h-bridge chip anyway running some weird code. i'm very new to steppers and having the hardest time with them for some reason.
so i hooked up the big easy driver just like in this tutorial: http://bildr.org/2012/11/big-easy-driver-arduino/#mototPairs
ran the code from the page (one_stepper_example.ino)
uploaded it to arduino, gave the easy driver 12V. the light on the driver turned on, the arduino took the code, but there is 0 reaction from both steppers i tried. i multimetered everything out and it's going where it should, i think. there is one thing, though, that when i multimeter from the stepper wire onto the easyDriver board, it is a little strange. A1 beeps for A1, but when I test A2 to A2 nothing beeps. A2 does beep, though, on A1. Same exact thing with the B wires. I assume this is because there is resistance in the motor and stuff like that i don't understand. does everything sound hooked up correctly? and if it is hooked up correctly, any idea why i'm getting no response from the motor? i'm using a 12V 5A wall wort. I messed around with the potentiometer on the driver also to no avail.
here's what the board looks like in case anyone could notice any glaring mistakes... https://dl.dropboxusercontent.com/u/7072449/2013-06-06%2017.27.21.jpg
thanks so much for any feedback
