I bought a tb6560 3rd generation 4 axis board, while setting it up the cd that came with it would not load the wiring diagram so i wired it up like a normal tb6560 board and the motors wouldnt move but made noise. turns out i had the a- and b- mixed up i managed to find the corect wiring diagram. now that its hooked up properly the motors move but have little to no power they act as if they are not getting enough power to run properley. and theyre not running smoothly ethier. I went ahead and bought a stock tb6560 board off of ebay about an hour ago. but i cant help but wonder if the board had incorect dip settings from the factory
