How to Power a Raspberry Pi from a 3D Printer Using Your Printer's Power Supply Unit (PSU)
This guide will show you how to power a Raspberry Pi using your 3D printer's power supply. This is especially useful if you're using OctoPrint and only want to run your Pi when your 3D printer is running.
In a nutshell, we're going to connect our printer to a small voltage regulator, also known as a "buck converter" or "step down converter", to reduce the printer's higher voltage to the 5V needed by the Pi.
This guide will work for any Raspberry Pi model, including the Raspberry Pi 4.
Important note: This guide involves electricity. Take proper precautions even when working with low voltages.
