AMS Active Support Shaft Assembly

Bambu Lab AMS Active Support Shaft Assembly

The AMS Active Support Shaft Assembly is a driven roller that supports the filament spool while actively rotating it during filament feeding and rewinding inside the Bambu Lab AMS. By assisting spool movement, it reduces drag and helps maintain smooth, consistent filament delivery during printing and material changes.

Replacing this part can help resolve spool slipping, uneven rotation, or feeding resistance within the AMS.
