So I was thinking of adding USBC PD to my ender 3v2 for a off grid setup. Is it possible or have I gone mad with USBC? I know it’s possible with my old monoprice select mini because of its low power requirements.
Not very likely. USBc-PD is 20v/5a . Most printers are either 12 or 24 volt rails, at 40 or more watts of power for the hotnend alone, toss in the stepper motors, the fans, the board running and you’re very close to going anemic on the power supply.
You probably could get away with a resin printer, though, that doesn’t have the massive hot end. Some kind of transparent LCD (laptop screen disassembled? or maybe the old school kindle e-reader LCD’s) and UV led strips/arrays under it should be fairly easy to build and run.
