Bambu Lab Filament Buffer

Spring-loaded buffer module between the AMS/spool and the extruder that absorbs slack and tension differences, and signals the AMS when to feed more filament. A faulty buffer causes feed jams, grinding, or constant AMS retry errors. This Filament Buffer is a genuine Bambu Lab replacement part for the Bambu Lab H2S.

When to Replace

• HMS filament buffer signal error
• Filament jams between AMS and extruder
• AMS repeatedly retrying filament feed
• Clicking or inconsistent extrusion with AMS

Compatible With

• H2S
