AMS briefly detects Bambu RFID, then loses filament data

Bambu Lab X1 Series Troubleshooting

  • Detailed description of the problem

I have an AMS that’s less than a month old. I recently bought Bambu PETG-HF and loaded the AMS with it. Upon loading, AMS briefly detects the filament spool’s RFID tag and shows the correct filament type (PETG-HF) and color (eg: orange), along with an eye symbol below the filament type on the printer’s touchscreen. A few seconds later, the filament type just reverts to ‘?’ and attempting to manually input the filament brand and type result in ‘?’ appearing again.

I power cycled the printer and AMS, but this didn’t change anything.

  • Any potentially useful information that is related to the problem

Up until today, loading non-Bambu branded filament and manually entering filament brand and type values has worked without issue. After the issue with the AMS failing to detect/store filament values correctly, attempts to manually enter filament info for non-Bambu filament are also failing. Is the AMS just toast? I’ve heard reports of poor QC on these units, but hoping this isn’t the issue on a nearly brand new unit.

If you have Orca studio open and connected to your printer it will do this. Orca studio doesn’t have PETG HF data yet in the release version. You need to add your own custom filament with the same settings as the Bambu one and manually select it to prevent this from happening.
