Just purchased my first kit for my first 3D printer. It has a Sanguinololu 1.3a. It is an Eventorbot and has the board built. My question is if I need to change the incoming amps when running the 12v+ from an atx Power supply. The designer of this printer said that I need 5 amps without the heated bed and 10 with. My PS puts out 19 amps. Will it hurt anything to just run straight into the boarby buzzbbird - Sanguino(lolu)
