Issue 1: Spool detection only checked tray_uuid/tag_uid, missing spools
that have tray_info_idx (Bambu preset ID like "GFG02") but incomplete
RFID data.
Issue 2: Partial MQTT updates from printer could overwrite complete tray
data, causing loss of tray_sub_brands, tray_id_name, and other fields.
Backend changes (services/spoolman.py):
- Add tray_info_idx to AMSTray dataclass
- Parse tray_info_idx from raw MQTT data
- Check tray_info_idx first in is_bambu_lab_spool() (GF* prefix)
- Fall back to tray_uuid then tag_uid for identification
- Add warning when Bambu spool detected but no unique ID for Spoolman
Backend changes (api/routes/spoolman.py):
- Pass tray_info_idx to is_bambu_lab_spool() in both sync endpoints
- Guard against empty spool_tag when adding to tracking set
Backend changes (services/bambu_mqtt.py):
- Implement deep merge at tray level for AMS MQTT updates
- Preserve existing tray fields unless new update has non-empty value
- Numeric fields (remain, k, id, cali_idx) always update
Frontend changes (pages/PrintersPage.tsx):
- Add isBambuLabSpool() helper with same detection logic as backend
- Check tray_info_idx (GF*), tray_uuid, and tag_uid
- Update all 4 vendor detection locations in AMS cards
The spool detection only checked tray_uuid and tag_uid, but some Bambu Lab
spools have RFID read issues causing these to be missing while still having
valid tray_info_idx (Bambu filament preset ID like "GFA00").
Backend changes (backend/app/services/spoolman.py):
- Add tray_info_idx to AMSTray dataclass
- Parse tray_info_idx from raw MQTT data in parse_ams_tray()
- Check tray_info_idx first in is_bambu_lab_spool() - most reliable indicator
- Bambu Lab presets start with "GF" (GFA00, GFB00, GFL00, etc.)
- Fall back to tray_uuid then tag_uid for unique spool identification
- Add warning when Bambu spool detected but no unique ID for Spoolman
Backend changes (backend/app/api/routes/spoolman.py):
- Update /sync/{printer_id} and /sync-all to pass tray_info_idx
- Guard against empty spool_tag when adding to tracking set
Frontend changes (frontend/src/pages/PrintersPage.tsx):
- Add isBambuLabSpool() helper with same detection logic as backend
- Update all 4 vendor detection locations in AMS cards to use new helper
Detection priority (same on frontend and backend):
1. tray_info_idx starts with "GF" (Bambu preset ID)
2. tray_uuid is valid 32-char hex (non-zero)
3. tag_uid is valid 16-char hex (non-zero)
The spool detection logic only checked tray_uuid (32 hex chars) to identify
Bambu Lab spools. Some spools have RFID read issues causing missing or
invalid tray_uuid while still having valid tag_uid (16 hex chars).
Changes:
- Update is_bambu_lab_spool() to accept tag_uid as fallback parameter
- Prefer tray_uuid for identification, fall back to tag_uid if invalid
- Use whichever valid identifier for Spoolman tag storage and matching
- Update both /sync/{printer_id} and /sync-all endpoints
This fixes spools being incorrectly marked as "Non-Bambu Lab spool (no RFID
tag)" when they have valid tag_uid but missing/zero tray_uuid.
New feature: Publish BamBuddy events to external MQTT brokers for integration
with Home Assistant, Node-RED, and other automation platforms.
Backend changes:
- New MQTTRelayService (backend/app/services/mqtt_relay.py) with paho-mqtt
- MQTT settings added to AppSettings schema (enabled, broker, port, auth, TLS)
- New /settings/mqtt/status endpoint for connection status
- Event hooks in main.py, print_queue.py, print_scheduler.py, maintenance.py, smart_plugs.py
- PrinterInfo class and get_printer() method added to PrinterManager
- MQTT reconfiguration added to backup/restore flow
- Printer status throttled to 1 update/sec to avoid flooding
Frontend changes:
- New "Network" tab in Settings (between Filament and API Keys)
- FTP Retry settings moved from General to Network tab
- MQTT configuration card with broker, port, TLS toggle, auth fields
- Port auto-populates when TLS toggled (1883 ↔ 8883)
- Connection status indicator (green/red dot) in tab and card header
- Real-time status polling when on Network tab
Published topics:
- bambuddy/status - Online/offline
- bambuddy/printers/{serial}/status - Printer state (throttled)
- bambuddy/printers/{serial}/print/* - Print lifecycle
- bambuddy/printers/{serial}/ams/changed - AMS changes
- bambuddy/queue/* - Queue events
- bambuddy/maintenance/* - Maintenance alerts
- bambuddy/smart_plugs/* - Plug state/energy
- bambuddy/archive/* - Archive events
Tests:
- Added MQTT settings and status endpoint tests
Closes#78
Fix Applied:
1. Added supports_chamber_temp() helper function that returns True only for X1/X1C/X1E, P2S, and H2 series
2. Modified printer_state_to_dict() to filter out chamber, chamber_target, chamber_heating from temperatures for unsupported models
3. Added model caching in PrinterManager so we can look up the model without a database query
4. Updated all callers (main.py, websocket.py) to pass the model
The chamber temperature widget will now simply not appear for P1S/P1P/A1/A1Mini printers since the temperatures.chamber field won't be sent to the frontend.

The previous fix only skipped SSL session reuse for A1 printers but
still wrapped the data channel in SSL. VREmma's testing (issue #31)
showed that A1 printers need the data channel to not be SSL-wrapped
at all - they timeout waiting for transfer completion responses.
The fix:
- X1C/P1S: SSL with session reuse on data channel (required by vsFTPd)
- A1/A1 Mini: No SSL on data channel (control channel remains encrypted)
This matches VREmma's working fix (c723f25) which set ftplib._SSLSocket
to None, but implemented properly within the ImplicitFTP_TLS class.
Fixes#31
Thanks VREmma!
Resolves FTP transfer failures on A1/A1 Mini printers caused by SSL
session reuse incompatibility. Also adds configurable FTP timeout
setting for slow WiFi connections.
Changes:
- Add SSL session reuse bypass for A1/A1 Mini printers (auto-detected)
- Add printer_model parameter to FTP functions for model detection
- Add configurable FTP timeout (10-120s, default 30s) in Settings
- Update all FTP callers: archiving, reprint, timelapse, firmware upload
Technical details:
- A1/A1 Mini printers don't support vsFTPd's SSL session reuse
- X1C/P1S continue to use session reuse as required by their FTP server
- ImplicitFTP_TLS now accepts skip_session_reuse flag
- BambuFTPClient auto-detects A1/A1 Mini and sets flag accordingly
Previously, when syncing to Spoolman, the location field was set to the
printer/AMS slot but was never cleared when the spool was removed from
the AMS.
Now during sync, the system tracks which tray UUIDs are currently in the
AMS and clears the location for any spools that were previously at this
printer but are no longer present.
Changes:
- Add clear_location parameter to update_spool() method
- Add find_spools_by_location_prefix() to find spools at a printer
- Add clear_location_for_removed_spools() to clear stale locations
- Update sync_printer_ams and sync_all_printers endpoints to clear
locations for removed spools after syncing
Features:
- Add print options UI to reprint modal (bed leveling, flow calibration,
vibration calibration, first layer inspection, timelapse)
- Collapsible "Print Options" section with toggle switches
- Default values: bed leveling=on, vibration_cali=on, others=off
Fixes:
- Fix AMS mapping format to match Bambu Studio exactly
- Use slot_id from 3MF to position tray IDs correctly
- Fill unused slots with -1 placeholder
- Add ams_mapping2 with detailed {ams_id, slot_id} pairs
- Fix print command format for proper printer recognition
- Add auto_bed_leveling, cfg, extrude_cali_flag, nozzle_offset_cali
- Use American spelling "bed_leveling" (not British "bed_levelling")
- Match sequence_id format from official apps
- Prevent duplicate tray assignment in filament matching
This resolves the "stuck at filament change" issue on multi-color reprints
affecting X1C and other multi-AMS printer configurations.
The delete_archive() function in backend/app/services/archive.py now has these safety checks:
1. Empty path check: Refuses to delete files if file_path is empty/whitespace
2. Path containment check: Verifies archive_dir is inside settings.archive_dir
3. Depth check: Ensures we're at least 1 level deep inside archive directory
4. Logging: All security refusals are logged with SECURITY prefix
5. Database record still deleted: Even if file deletion is refused, the orphan DB record is cleaned up
Before the fix:
file_path = settings.base_dir / archive.file_path # If empty: /opt/bambuddy
archive_dir = file_path.parent # = /opt
shutil.rmtree(archive_dir) # DELETES /opt!

1. "Unknown Status (255)" bug
File: backend/app/services/printer_manager.py:291-293
Problem: A1/P1 printers send stg_cur=255 when idle (unlike X1 which uses -1). The code treated 255 as a valid stage number and returned "Unknown stage (255)".
Fix: Changed the condition from if state.stg_cur >= 0: to if 0 <= state.stg_cur < 255: so that 255 is now treated as "no calibration stage" (same as -1).
2. AMS humidity/temp displaced on mobile
File: frontend/src/pages/PrintersPage.tsx:1164-1212
Problem: The AMS row used a rigid horizontal flex layout that didn't adapt to narrow mobile screens, causing humidity/temperature indicators to be displaced.
Fix:
- Added flex-wrap to allow wrapping on very narrow screens
- Added ml-auto to humidity/temp section to keep it right-aligned
- Added max-w-[60px] sm:max-w-none to truncate long filament names on mobile
- Changed gap from fixed gap-3 to responsive gap-2 sm:gap-3
Tests Added
4 new unit tests for get_derived_status_name:
- test_stg_cur_255_returns_none - Verifies A1/P1 idle state
- test_stg_cur_negative_one_returns_none_when_idle - Verifies X1 idle state
- test_valid_stage_returns_name - Verifies valid stages work
