I’m using the 12V line on this power supply: https://www.sparkfun.com/products/11296
The code isn’t the exact same, but close enough. I’m using a Netduino instead of an Arduino, but the code is pretty much the same: turn a pin off then on, sleep for 1 ms, repeat. I do this for 2000 steps, then reverse the direction. I’ve been able to verify that the voltages coming out of the Netduino step and direction pins are good, and that the power coming into the BED is good (12V, 2A). A friend and I did some other testing, and noticed that the 3v/5v jumper was connected (it came from Sparkfun this way). I would think that this means that it expects a 5v input as well to control the logic, so we tried hooking it up to the 5v line off the Netduino, but still no dice. The power light on the BED comes on, as expected, but there’s absolutely no output going to the motor. Any ideas?
I’m having the same problem with a board I bought a year and a half ago. Did you ever find out what it was? Was the board bad?
