Re: motors just whine but don't spin

Figured I'd give an update. Inventables sent a new grbl shield and the problem persisted. After that they sent a validated pair of Arduino and shield and everything works fine. I sent the originals back to them, but I doubt I'll hear back. (It is hard to justify spending time to debug a $20 board.) ...
