### Accurate Nozzle Offset Calibration This sensor precisely detects the position of both nozzles and performs automatic offset calibration. It effectively reduces printing deviation and layer misalignment to ensure that the two print lines from the dual nozzles are perfectly aligned. ### High Sensitivity Chip Stable Output Built with a high precision sensor chip that delivers stable signal output and fast response. Supports the X2D's automatic nozzle detection routine at the start of every print to confirm proper hotend installation. ### Industrial Grade Durable Construction Designed with anti interference and high temperature resistance for long lasting reliability. Provides consistent performance even under frequent printing conditions where the sensor is repeatedly contacted by the hotend. ### Plug and Play Installation Standard connector and reserved mounting holes allow quick installation and easy replacement. Package includes 2 mounting screws. The sensor is mounted at the rear of the heatbed. Refer to Bambu Lab Wiki for detailed replacement steps. ### Restore Print Quality When dual nozzle prints show layer shifts or misalignment that cannot be fixed by software calibration, a faulty sensor is often the cause. Replacing it restores the X2D's automatic calibration function and helps keep your dual color prints accurate.
