I've had an MKS SBASE 1.3 for a while now. And an old printer that was in need of a control board. Mating the two, I now have a mostly working printer, but before I clog up the extruder again, how do people wire up two fans with this board? Modern (apparenly "newer" than the SBASE) have two fans, one for the hotend and one for cooling the print....
