Replacement Tips

1. Confirm it’s the AMS buffer board – This part is for the original AMS filament buffer (not AMS Lite).
2. Power off first – Unplug the printer/AMS before opening the buffer and disconnecting cables.
3. Reseat the connector – Loose plugs can cause intermittent sensor readings; reseat before replacing.
4. Keep the buffer clean – Filament dust buildup can affect smooth buffer movement and sensor readings.
