## Summary description

Replacement hotend adapter board designed by Creality for use with K2 Pro and K2 Plus printers (MPN 4004010288). This board provides the electrical interface and mounting compatibility for the printer hotend, enabling stable temperature control and reliable connection to the printer mainboard. Use it to repair or upgrade a malfunctioning hotend assembly and restore printing performance.

## Long description

The Creality Hotend Adapter Board for K2 Pro/Plus is a replacement control board designed to interface the hotend assembly with the printer mainboard. It restores electrical connectivity and provides the mounting and signal pathways required for stable temperature regulation and heater/thermistor communication. Intended for use in Creality K2 Pro and K2 Plus machines, the adapter board helps bring a malfunctioning or damaged hotend assembly back to operational status without replacing the entire hotend.
Advantages
This adapter board offers direct compatibility with the specified Creality K2 series hotend geometry and connector layout, enabling straightforward fitment and reduced installation effort. It supports reliable heater and thermistor signaling to the mainboard, which helps maintain consistent nozzle temperature during prints. The board’s design minimizes the need for custom wiring or adapters, and it allows targeted repairs that are more cost-effective than full hotend replacement.
Suitable for
 Repairing a K2 Pro or K2 Plus printer with a faulty hotend connection
 Replacing a damaged hotend interface board to restore temperature control
 Maintaining or refurbishing used K2 series hotend assemblies
 Service operations where a direct-fit hotend adapter board reduces downtime
Key specifications
 Form factor: compact adapter board sized for K2 Pro/Plus hotend mounting
 Electrical interface: heater output and thermistor input compatible with Creality mainboard signaling levels
 Connectors: dedicated connectors for heater, thermistor and mounting harness (direct-fit layout)
 Mounting: screw holes and pad layout matching the hotend assembly for secure installation
 Operating temperature: rated for typical 3D printer hotend environments
How to use
Power down the printer and follow standard safety procedures before starting. Remove the hotend carriage cover or shroud to access the existing adapter board, disconnect the heater, thermistor and any associated harnesses, and unfasten the existing board. Position the replacement adapter board on the hotend assembly so that connectors and mounting holes align, secure with appropriate screws, and reconnect the heater and thermistor leads to the corresponding terminals. Refit covers and perform a controlled power-on. Verify thermistor readings and perform a cold-to-hot temperature check to confirm stable temperature control before resuming normal printing operations.
Usage recommendations
Use the adapter board only with compatible K2 Pro or K2 Plus hotend assemblies and Creality mainboards. Ensure proper polarity and connector seating to avoid short circuits. If temperature readings are abnormal after installation, recheck wiring and connector integrity and, if necessary, consult Creality support or a qualified technician for diagnosis.
