It seems I'm doing something wrong.
I can't update to v0.2.2b2. I've reverted to v0.2.1.1. It works correctly there.

@maziggy commented on GitHub (Mar 5, 2026):

Can you explain, what

"I added a new filament to slot 4 of the AMS"

exactly means? What di you do exactly?

The A1's AMS Lite doesn't have an RFID reader, so filaments won't auto-detect — you'd need to configure them on the printer screen or in your slicer.

Can you check: does slot 4 show up on the printer's screen with the filament loaded? If the printer itself shows 4 filaments but BamBuddy only shows 3, that's something I can fix on my end. If the printer screen also doesn't show it, the filament may not be fully seated.

Yes, the printer shows the slot as loaded.
AMS Lite has RFID.
I've attached a screenshot of the previous version.

Thank you very much and best regards.
