AMS Feeds, Extruder Rejects Filament – H2D Filament Buffer Replacement #fixed #bambulab #3dprinting

If your Bambu Lab H2D / H2C / H2S refuses to load filament, even though the AMS feeds correctly and the filament reaches the extruder, this video shows a real-world fix.

In this case, the filament exits the AMS, passes through the filament buffer, reaches the extruder — and is immediately rejected.
The extruder reverses, unloads the filament, and throws repeated filament resistance or buffer-related errors.

The issue was resolved by replacing the filament buffer.

This video shows:
-The exact error behavior
-A fast unboxing of the replacement filament buffer
-A quick buffer replacement
-Final confirmation with successful filament loading

⚠️ Important:
If you plan to replace the filament buffer yourself, make sure to follow the official Bambu Lab replacement guide to avoid damage:
