I'm building my first 3D printer (i3) and I have been thinking it through like this: If I go to 24 volts, my currents will be half of the 12V and mr. Ohm says it's good thing as P = UI and P = RI^2.
I can lower motor driving currents, get bit more faster actions, connect Z in series and heat my wires and FETs less.
I planned to take D1 off and check the caps. Also I consider powering Arduino through Raspberry Pi's USB port. On Pi I'll be running Octopi.
Only thing I'm missing is some 24 volt power supply which I can control with PS_ON pin. Does anyone know where to get such PSU? Or is my plan already doomed?
