    I have this BOB and have just wired it up. Sorry, don't have a photo. Its a DB25-1205. Came free with DQ860MA drivers from Wantai.

    5V power on the RH side, step and direction along the bottom, and inputs such as e-stop, limits on the LH side

    Wiring is:

    great news :] i wired the motors the correct way round (still did not work)
    i added enable- wires to the BoB and set pins 1,16, and 17 as the enable- (still did not work)
    then i turned on step low active and it worked :) it looks and sounds good to me :)
    the only problem i have is that when i tested all 3 motors at once one started to lag, as though there is not enough power for all 3 to be on full motion at the same time, does this sound familiar or maybe something needs tweaking ?
