Questions tagged [switching-power-supply]
A switched-mode power supply (also called an SMPS or "switcher") converts electrical power from one state to another. An SMPS can for instance be used to convert power from an electrical wall outlet into a voltage, frequency and amperage usable by smaller electronic circuits.
I'm going to add a Raspberry Pi to my printer, which requires a 5 V source. I want to take this opportunity to also power the Arduino with that same source, as dropping 12 V -> 5 V is a quite big ...

What is the power consumption of your heatbed (size) and hotend (model)?
I want to verify that it is possible to use a battery to power them.

As long as there's a MOSFET in between, can I supply 24 V bed/extruder heat from an ATX power supply using -12 V and +12 V and ignoring the common rail?
I assume so, I can't think of a ...
