Product Description

Bambu Lab Nozzle Eddy Sensor FAC205 – left nozzle is an original spare part for the Bambu Lab X2D 3D printer. It is an eddy current (inductive) sensor located at the left nozzle, which monitors the nozzle status during printing.

The sensor can recognize if the nozzle is wrapped in melted filament and provides feedback to the printer for various automatic routines (e.g., calibration, print error detection). It thus helps prevent nozzle collisions with the build plate, issues with the first layer, and reduces the risk of print head damage during material buildup.

This specific model FAC205 is intended for the left nozzle (Left) in the dual toolhead of the X2D printer.

Key Features

• Original Bambu Lab spare part (FAC205) – guaranteed compatibility and quality
• Eddy current sensor at the left nozzle – detects nozzle wrapping with melted filament
• Automatic calibration support – contributes to precise nozzle height adjustment and safe homing
• Printer protection – helps detect problematic situations (e.g., plastic buildup on the nozzle) that could lead to damage or print failure
• Compatibility with Bambu Lab X2D – designed for the dual toolhead of this series
• Compact and lightweight design – minimal impact on the toolhead weight

Package Contents

• 1× Bambu Lab Nozzle Eddy Sensor FAC205 – Left (left nozzle)
• 1× BT2-6 screw for securing the sensor

Note: The package does not include wiring or other parts of the print head. Before replacing the sensor, we recommend turning off the printer and following the manufacturer's official instructions.

Compatibility

• Bambu Lab X2D

The sensor is intended exclusively for the left nozzle within the X2D toolhead. It is not interchangeable with the right sensor (Right) or with eddy sensors from other printer series.

Technical Parameters

Usage and Practical Benefits

• More stable first layer – the sensor helps with precise adjustment of the nozzle-to-bed distance, which is key for good adhesion.
• Early problem detection – if the nozzle becomes excessively wrapped in filament, the sensor allows the printer to recognize the situation and prevent further damage.
• Lower risk of hardware damage – protection against nozzle collisions and material buildup saves both the print head and the build plate.
• Higher reliability for long prints – especially for long and demanding jobs where a hidden nozzle problem could lead to significant time and material loss.

Installation and Recommendations

• Before replacing the sensor, turn off the printer and disconnect the power.
• Follow the sensor orientation according to the manufacturer's assembly instructions.
• After installation, we recommend performing calibration and a test print to verify the correct function of the sensor.
• For maximum sensor and head life, regularly clean the nozzle and hotend area of filament residue.
