When reprinting a multi-plate 3MF file exported with "All sliced file",
the system now asks which plate to print and only maps filaments for
that specific plate.
Backend changes:
- Add GET /archives/{id}/plates endpoint to list available plates
with thumbnails, print times, and per-plate filament requirements
- Add GET /archives/{id}/plate-thumbnail/{index} for plate thumbnails
- Update GET /archives/{id}/filament-requirements to accept plate_id
query parameter for filtering filaments by plate
- Add plate_id field to ReprintRequest schema
- Update POST /archives/{id}/reprint to use plate_id from request body
instead of auto-detecting (maintains backward compatibility)
Frontend changes:
- Add getArchivePlates API method
- Update getArchiveFilamentRequirements to accept optional plateId
- Update reprintArchive to accept plate_id in options
- Add plate selection UI to ReprintModal when multi-plate 3MF detected
- Show plate thumbnails, names, and filament counts in selection grid
- Require plate selection before printing multi-plate files
- Filter filament requirements to show only selected plate's filaments
Tests:
- Add unit tests for multi-plate slice_info.config parsing
- Add unit tests for plate detection from gcode files
- Add integration tests for new plate endpoints
When exporting individual plates from a multi-plate 3MF in Bambu Studio,
all uploaded archives showed plate 1's name and thumbnail regardless of
which plate was actually exported.
Root cause: The 3MF parser used an incorrect XPath lookup (plate_idx
attribute) and didn't extract the plate index from slice_info.config
metadata.
Changes:
- Extract plate index from <metadata key="index" value="N"/> in
slice_info.config
- Remove incorrect plate[@plate_idx='N'] XPath lookup that doesn't
work for single-plate exports
- Set self.plate_number from extracted index so _extract_thumbnail()
uses the correct plate thumbnail (e.g., plate_5.png instead of
plate_1.png)
- Append " - Plate N" to print_name when plate index > 1 to
distinguish multi-plate exports
- Add 7 unit tests for plate index extraction and print_name

Resolves#90
The REST API endpoint GET /printers/{id}/status was returning raw
temperatures without filtering based on printer model. WebSocket
broadcasts correctly filtered chamber temp via printer_state_to_dict(),
but the REST endpoint built its own response and bypassed this filter.
When users added a second printer, the frontend would fetch initial
status via REST API, causing chamber temp to reappear on printers
that don't have a chamber sensor (A1, A1Mini, P1P, P1S).
Changes:
- Import supports_chamber_temp in printers.py
- Filter chamber/chamber_target/chamber_heating in get_printer_status()
Fixes#82
Track individual parts/objects separately from print plates in projects.
Useful for multi-part builds like Voron where 25 plates produce 150 parts.
Backend:
- Add target_parts_count field to Project model
- Calculate parts_progress_percent and remaining_parts in stats
- Auto-detect quantity from 3MF printable objects when archiving
- Sum archive quantities for completed_count (parts)
- Use archive_count for plates progress
Frontend:
- Add "Target Parts" input in project create/edit modal
- Show separate progress bars for plates vs parts
- Stats footer displays both plates and parts count
- Header badge shows parts progress when target set
Scripts:
- Add update_archive_quantities.py to migrate existing archives
Tests:
- Add 5 integration tests for parts tracking
- Add 3 unit tests for 3MF object extraction
Closes#85
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.
The cover and objects endpoints only tried downloading files with the
.gcode.3mf extension pattern, but files uploaded directly (not sliced
via Bambu Studio) are stored as plain .3mf files.
This caused FTP error 550 (file not found) when trying to display cover
images for prints started from BamBuddy archive.
Now tries both naming patterns:
- {name}.gcode.3mf (sliced via Bambu Studio)
- {name}.3mf (uploaded directly)
Fixes#79
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

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.

- 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
Added:
- Archive list view: edit/delete buttons and context menu with full feature parity

- Spoolman: clear location when spools are removed from AMS
Fixed:
- QR code endpoint 500 error (added qrcode[pil] dependency)
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.
