Consider replacing the Hotend Adapter Board if you experience damaged heater or thermistor connectors, hotend communication problems, temperature-reading errors, intermittent heating, or visible physical/electrical damage to the PCB. The board can also be damaged during removal of a severe filament buildup or “blob” around the hotend, particularly if the small connectors are accidentally pulled or broken. Package Includes 1 × Creality K2 / K2 Pro / K2 Plus Hotend Adapter Board Important Notes This is the Hotend Adapter Board, not the complete hotend or the main Toolhead Board. Creality lists the main K2/K2 Pro/K2 Plus Toolhead Board separately. Always power off and unplug the printer before replacing electronic components. Carefully verify all connectors and cable orientation before powering the printer back on.
