When auto-archive was off, archive_id was None at print completion so
the entire 3MF tracking path was skipped. AMS remain% fallback also
failed on printers reporting remain=-1. Now searches library files and
previous archives by filename to locate the 3MF without an archive,
and captures the AMS slot-to-tray mapping at print start so it's
available at completion regardless of archive state.
When a spool runs empty mid-print and the AMS auto-switches to a backup,
the entire print weight was attributed to the original spool. Track tray
changes during the print via tray_change_log on PrinterState, then split
the 3MF weight across trays using per-layer gcode segment boundaries at
print completion. Falls back to linear layer-ratio splitting when gcode
data is unavailable.
Add color-matching fallback for slot-to-tray mapping on printers that
don't provide the MQTT mapping field (snow encoding) or reject request
topic subscription. Matches 3MF filament slot colors against AMS tray
colors to resolve the correct physical tray. Returns no match when
colors are ambiguous (duplicate tray colors) to safely fall through
to existing fallbacks.
Mapping priority chain: print_cmd → MQTT snow → queue → color match →
tray_now → slot_id-1.
On dual-nozzle printers (H2C, H2D Pro) with multiple AMS units, usage
tracking attributed filament consumption to the wrong spools. The MQTT
mapping field — a snow-encoded array mapping slicer slots to physical
AMS trays — was preserved in state but never parsed.
Add _decode_mqtt_mapping() to convert snow encoding (ams_hw_id * 256 +
slot) to bambuddy global tray IDs. Insert as priority 2 in the mapping
resolution chain, after print_cmd ams_mapping but before queue/tray_now
fallbacks. Works for all printer models and print sources.
Usage tracking works on X1E but fails on H2D Pro — the wrong tray
is identified, attributing usage to the wrong spool. The root cause
is unknown because we don't know what MQTT mapping data each printer
model reports.
Adds INFO-level logging at print start and completion:
- state.raw_data["mapping"] (unknown format, preserved but never parsed)
- tray_now, last_loaded_tray values
- All raw_data keys containing "map" (discovery)
- Per-AMS-tray summary: tray_type, tray_color, tray_now, tray_tar
This enables comparing MQTT behavior across printer models without
requiring DEBUG mode, so testers can send normal logs.
Three fixes for inventory spool usage not updating after prints:
1. Store ams_mapping from print command (reprint, library print, queue)
so the usage tracker maps 3MF slots to the actual physical trays
the user selected, not the default slicer mapping.
2. Track last_loaded_tray on printer state — the last valid tray_now
(0-253) seen during printing. On H2D printers, tray_now is always
255 in AMS data; the real tray resolves via snow field ~44s after
print start but reverts to "unloaded" at completion. The fallback
chain is: tray_now_at_start > current tray_now > last_loaded_tray.
3. Use color similarity (Euclidean RGB distance, threshold 50) instead
of exact hex match for auto-unlink fingerprint checks. RFID sensors
report slightly different shades across reads (e.g. distance ~43.6
for the same spool), causing false assignment unlinks after prints.
3MF slicer estimates are now the primary tracking source for ALL spools
(BL and non-BL), with AMS remain% delta as fallback. Per-layer G-code
analysis provides accurate partial usage for failed/cancelled prints.
Fix wrong-spool tracking bug: 3MF slot_id was mapped directly to AMS
tray position, but the printer remaps slicer slots at print time. Now
uses queue ams_mapping for queue prints and tray_now from printer state
for single-filament non-queue prints.
Add filament_grams, filament_details, and progress template variables
to print_complete, print_failed, and print_stopped notification events.
Webhook payloads include per-slot filament breakdown. Per-slot data
stored in archive extra_data during 3MF parsing.
