    It is looking that the problem is the board is not self powered standalone.
    According to me the logic side either requires USB or the standard 2.1mm round coaxial power jack 5V.
    There are 2 through holes on the board labeled ground and 5V. That pair is directly in parallel with the round 5V logic input.
    Pretty sure they used the standard USB power switch setup to prevent backfeeding up USB.

    I performed the same mod as Jetguy (Thanks Jetguy!) which seems to be working quite swimmingly:

    I finally finished all of the hardware work on my printer and will hopefully try a print this weekend (though I am patiently awaiting v.0.93 auto-leveling support)..

    Update on performance?

    Hi! Was just wondering if anyone had a chance to print with it? If yes, what are the performance gains? I've read it's compatible with any kind of printers, is that true? Got a makerbot replicator 1 and a wanhao i3.

    Is there anyone who is able to print with this board yet? I got one and I've been trying all day to get it to print but it's living it's own life?

    I need a board for 6 steppers due to dual Z motors and dual extruder motors? Is there any other board available?
