A fairly typical heated bed presents a 1 ohm load to the power system. That could work out to 12A on the 11A line. A 40W heater on the extruder will pull 3.33 A. Past that you have 6 motors with two...

A dedicated IC will likely be faster than a cheap uC. There are several dedicated control IC's that work with external FET's. You will need the big FET's and major heatsinks regardless of how you do...

Assuming that the board is set up in a conventional fashion, I'd bet you don't have 12V to all of the board. Either there's a wire loose or a fuse has done its thing.
