A damaged or malfunctioning hotbed can lead to a host of printing problems, from failed first-layer adhesion and uneven heating to electrical faults. Whether you're replacing a warped aluminum bed, a shorted heating element, or upgrading to a different build surface, this guide walks you through the process of replacing the entire hotbed assembly on your Ender 3 S1, S1 Pro, or S1 Plus. We'll cover the critical steps: safely disconnecting the power and thermistor wires from the mainboard, removing the bed from the Y-carriage, installing the new heated bed, and finally reconnecting and rerouting the cables with proper strain relief to prevent future issues . Remember to disconnect the printer from power and allow the bed to cool completely before starting.
