Bambu Lab Eddy Sensor Left and Right for X2D

The eddy sensor is installed between the hotend and the extruder and is used for actively calibrating filament flow. It monitors the filament as it feeds through, letting the printer correct flow in real time. The X2D uses two of them, one per nozzle, so a faulty sensor typically shows up as flow calibration errors or inconsistent extrusion on one nozzle while the other keeps working normally.
