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

This turned out to be multiple issues compounding:

FTP download failure → no 3MF tracking — When the 3MF file can't be downloaded from the printer (common on P1S), a fallback archive is created without the file. The primary usage tracking path (which reads filament weights from the 3MF) was skipped entirely because there was no file to read. Now Bambuddy will try to find the same 3MF from the file library or a previous print of the same file before giving up.
External spool (VT tray) never tracked by the fallback — The AMS remain% fallback (used when 3MF tracking isn't available) only looked at AMS unit trays. If you're printing from the external spool holder, the remain% delta was never captured or tracked. Now both AMS and external trays are tracked.
Notifications showing "Unknown" — Even when usage was tracked successfully, the notification still showed "Time: Unknown" and "Filament: Unknown" because the notification builder read from the archive record (which had no 3MF data) instead of using the usage tracker results. Now notifications are enriched with whatever tracking data is available, and fallback archives capture estimated print time from MQTT.

Available/Fixed in branch dev and available with the next release or daily build.

Please let me know if it works for you now.

@maziggy commented on GitHub (Apr 7, 2026):

The root cause: when auto-archive is disabled, no archive is created at print start, so at print completion there's no archive_id to look up the 3MF slicer data. The fix now:

Searches library files and previous archives by filename to find the 3MF even without an archive
Captures the AMS slot-to-tray mapping at print start so it's available at completion regardless of archive state

This means spool weight tracking will work whether auto-archive is on or off, as long as the 3MF exists somewhere (library, or a previous print of the same file).

Available/Fixed in branch dev and available with the next release or daily build. Please let me know if it works for you now.
