Bambu Lab Nozzle Offset Calibration Sensor is a dedicated component used for accurate nozzle position calibration in a compatible Bambu Lab 3D printer. The sensor is installed at the back of the heatbed and helps determine the correct nozzle offset during the calibration process. It supports precise positioning of the nozzle relative to the print surface and can be used as a replacement component when servicing or maintaining the printer’s calibration system.
