The filament is incorrectly detected when printing from Bambu Studio. There's PLA in the A1 slot, and it prints with it, but the Archive and Statistics show ASA.

@maziggy commented on GitHub (Apr 20, 2026):

The debug log attached was captured after the print finished, so it only contains FINISH-state frames — nothing about how Bambuddy resolved the filament during archive creation.

Please

Enable debug logging (https://wiki.bambuddy.cool/features/system-info/?h=debug#enable-debug-logging) before sending the next print from Bambu Studio, then leave it on until the print finishes and Bambuddy creates the archive. That captures slice_info, MQTT mapping, and tray_now transitions we need.
In Bambu Studio, what filament profile was selected in the slicer when you clicked Print? (Bambu Studio's "Max volumetric speed test" bakes the slicer's active filament into the gcode — if the profile was ASA but the AMS slot holds PLA, the printer prints PLA but the archive metadata says ASA.)
If possible, open the archive in Bambuddy and attach the .3mf / gcode it stored (Archive → menu → Download) — the slice_info.config inside tells us exactly what the slicer told Bambuddy was being used.
Please upgrade to dev branch (you're on 0.2.3.1) — nothing has changed in the filament-detection path recently but let's rule out stale fixes.

Sorry, my fault. I should have read the installation guide more carefully. I forgot about Step 4: Enable "Store sent files on external storage".
