Bambu Lab - AMS Internal Hub Unit

AMS Internal Hub Unit is specially designed for Bambu AMS. The AMS Internal Hub Unit is used to select specific filaments in the AMS and transport the filaments from the AMS to the printer. It also has speed measurement (filament transport) and filament detection functions.

When the sensor plate detects the insertion of the filament, the AMS First Stage Feeder automatically pulls the filament forward. If the filament insertion is abnormal, the sensor board will also identify it and pass this information back to the 3D printer.
