Bambu Lab AMS 2 Pro Internal Hub Unit [SAA038-V1] | Filament Hub Assembly for AMS 2 Pro - SAA038-V1

The Bambu Lab AMS 2 Pro Internal Hub Unit is a precision replacement component designed for the AMS 2 Pro automatic material system. Positioned at the rear of the AMS unit, this internal hub plays a critical role in managing filament selection and feeding, ensuring reliable multi-material printing performance.

Engineered with advanced sensing and drive technology, the hub integrates four Hall sensors, a magnetic rotary encoder, and a brushless motor to accurately detect filament position and control the feeding mechanism. This intelligent system merges four filament inputs into a single output channel and automatically selects the required filament for printing.

When a filament reaches a specific position inside the hub, the Hall sensor detects its presence and activates the motor to provide additional driving force. This ensures smooth, consistent filament transport from the AMS unit to the printer, helping prevent feeding interruptions during multi-material or multi-colour prints.

Designed as an official spare part, the hub unit allows users to restore or maintain the performance of their AMS 2 Pro system. It is ideal for replacing worn or damaged components to ensure accurate filament switching and reliable printing operations.
