Photonsters PTC Heater Unit for Elegoo Mars2 pro

thingiverse

It is made to fit in a small space of Elegoo mars2 pro. I think it can be used with Elegoo mars pro, but I haven't tried it. Just remove the filter unit and you don't need to process the housing. Use a wire with sufficient capacity or bundle multiple wires to supply power to the heater unit. I used AWG16 wire. (A maximum of 130W may flow.) W1209WK can be wired while assembled to the main body. Before assembling, clean the thread of the screw and the mating surface of the main body with sandpaper or a file. Since the post and cap are connected by thin pillars, they can be removed by twisting after curing. The heater unit and the printer are linked using a relay for automobiles. When you turn on the printer, the heater unit also turns on. I don't recommend it, but I've rewritten the firmware so that the heater unit only works during printing. This is useful for printing while you sleep or when you are away from the printer for a long time. Make sure the temperature sensor is inside the enclosure when using. My sensor holder is designed to prevent spilled resin from getting into the motor shaft. A fan mount is also available so that the removed carbon filter unit can be used if necessary. Supply power by branching from the heater unit. Required parts are M3 nuts and washer (4) for fixing post, M3 screws 18-20mm (2) for fixing switch panel riser, and wiring materials.
