This is so very similar to my problems. When my motor test fails (direction 1) it makes a series of beeps (sounds not sure if they are beeps), then moves to the other rotation direction. I am going to try and get a recording of it tonight also and upload to my posting.
Any help you all can give to my situation would also be appreciated. @blurfl has been most helpful already in identifying issues with the firmware and my Gcode.
