It is not recommended to use a 12V heater cartridge on an Ender 3 3D printer.
The Ender 3 3D printer is designed to work with a 24V power supply, and the heating elements, including the heater cartridge, are designed to operate at 24V. Using a 12V heater cartridge could cause several issues, including insufficient heating, slow heating, or even damage to the heating element or other components of the printer.
It is important to use the correct voltage and wattage for all components of the 3D printer, including the heater cartridge, to ensure proper operation and avoid potential safety hazards. If you need to replace a heater cartridge on your Ender 3 3D printer, it is recommended to use a 24V heater cartridge that is designed to work with your printer's specifications.
