Bambu Lab - AMS 2 Pro - Internal Hub Unit

The AMS 2 Pro Internal Hub Unit has been specially developed for the Bambu AMS 2 Pro. It is located at the rear of the AMS 2 Pro and consists of four Hall sensors, a magnetic encoder and a motor.

This unit combines four filament slots into one and is used to select specific filaments in the AMS 2 Pro and transport them from the AMS 2 Pro to the printer. The Hall sensor detects when the filament reaches a specific position and activates the brushless motor to provide additional driving force for the filament feed.
