yes, if you have the mosfet turned on. (ie heater circuit, hotend circuit. whatever).. just applying power to it wont do anything. its digitally controlled.

You definitely need both of the miniature fuses to be working. The stock ones are 5 amps, so I ordered 10 amp replacements
here from Mouser. Funny thing is, the fuse supplying the hotend blew, but there was never a short, or anything close to one. I checked carefully for that. I think running the hotend for 12 hours continuously may have stressed the fuse, so I got one with twice the capacity.
