The OTA update feature added update_status and update_message to the
SpoolBuddyDevice model but no ALTER TABLE migration, causing
"no such column: spoolbuddy_devices.update_status" on existing databases.

X1C and X1 virtual printers used legacy SSDP model codes
(3DPrinter-X1-Carbon, 3DPrinter-X1) that BambuStudio doesn't
recognize, causing "incompatible printer preset" errors when
sending prints. Changed to the correct codes (BL-P001, BL-P002)
that real printers report via SSDP.
Also fixed proxy mode auto-inherit storing printer display names
(e.g. "X1C") instead of SSDP codes, by adding a resolution layer
that maps display names to model codes.
DB migration auto-converts existing VPs on startup.
Per-printer camera rotation (0°/90°/180°/270°) for cameras mounted
in portrait or upside-down. CSS rotation for live views, Pillow
rotation for notification snapshots. Setting visible in external
camera config when enabled.
Printer File Manager Doesn't Auto-Refresh ([#704](https://github.com/maziggy/bambuddy/issues/704)) — The printer file manager (SD card browser) only fetched the file list once when opened. Files uploaded from BambuStudio/OrcaSlicer while the modal was open wouldn't appear until the user clicked the refresh button or reopened the modal. Now auto-refreshes every 30 seconds while open. Reported by @shadowjig.
Database Connection Pool Exhaustion Under Load ([#704](https://github.com/maziggy/bambuddy/issues/704)) — Background tasks (print scheduler FTP uploads, camera captures, notification sends, timelapse stitching) held database sessions open during slow network I/O, consuming connection pool slots for seconds at a time. With the default pool of 15 connections (size 5 + overflow 10), concurrent operations during print start/complete events could exhaust the pool, causing `QueuePool limit reached` errors and `greenlet_spawn` failures in RFID spool auto-assignment. Doubled the pool to 30 connections (size 10 + overflow 20). Reported by @shadowjig.
The migration that removes the UNIQUE constraint on smart_plugs.printer_id
used an exact substring match ("printer_id INTEGER UNIQUE") to detect the
constraint. Databases created with older SQLAlchemy versions may express
the constraint differently (quoted column names, table-level UNIQUE clause,
or separate UNIQUE indexes), causing the migration to silently skip.
Users hit "IntegrityError: UNIQUE constraint failed: smart_plugs.printer_id"
when assigning a second HA switch to a printer.
Replace the exact string match with regex pattern matching that handles
inline constraints, table-level UNIQUE(printer_id), quoted column names,
and standalone UNIQUE indexes.
Notify users when the first layer finishes printing so they can check
adhesion remotely. Triggers once per print when layer 2 begins
(layer_num >= 2, capped at <= 5 to handle reconnects). Includes a
camera snapshot attachment. Adds the on_first_layer_complete toggle
to all notification providers, with backend/frontend/i18n support
across all 7 locales.
Cloud credentials were stored globally — one Bambu Cloud account per
Bambuddy instance. When auth was enabled, any user logging into Cloud
overwrote everyone else's credentials. Credentials are now stored
per-user: each user gets their own independent Cloud login.
Also fixed cloud data endpoints (settings, fields, preset CRUD)
requiring settings:read/settings:update permissions instead of
cloud:auth — users who had "Cloud Auth" enabled but "Settings"
disabled couldn't load profiles after logging in.
Virtual printers in Queue mode now have an "Auto-dispatch" setting.
When enabled (default), prints start automatically — preserving current
behavior. When disabled, prints are added with manual_start so they
wait for manual dispatch from the queue UI.

Floating bug report button submits issues via bambuddy.cool relay (no GitHub
token needed locally). Collects 30s debug logs with printer push_all, sanitizes
all sensitive data, uploads logs as files to GitHub. Screenshot upload/paste/drag
with JPEG compression. Translated into all 7 languages. Includes 21 tests.
The slicer_binary_path key was left in the settings table from earlier
slicer integration research but is no longer referenced anywhere in the
codebase. Add a startup migration step that deletes orphaned settings
keys so they don't persist in backups.
Write NTAG213/215/216 tags for third-party spools via the SpoolBuddy
kiosk UI. New "Write" page with three workflows: existing spool, new
spool creation, and tag replacement. Backend encodes 133-byte OpenTag3D
NDEF payloads (material, color, brand, weight, temp). Daemon writes
page-by-page via PN5180 NTAG WRITE command with read-back verification.
Write commands flow through heartbeat polling with WebSocket status
updates. Includes 39 new tests and translations for all 6 languages.
SpoolBuddy's "Link to Spool" used the generic updateSpool API which only
set tag_uid, leaving tag_type and data_origin empty. Now uses linkTagToSpool
with tag_type='generic' and data_origin='nfc_link'.
Added a "Weight Check" inventory column (hidden by default) that compares
each spool's last scale measurement against calculated gross weight with
±50g tolerance. Shows green check for match, yellow warning + sync button
for mismatch. Backend stores last_scale_weight and last_weighed_at on each
spool when weight is synced via SpoolBuddy. Includes edge case handling
when scale weight < core weight. i18n keys added for all 6 locales.
Add weight_locked flag to spools that auto-sets when weight_used is
explicitly updated via the API. Both the MQTT AMS remain% auto-sync and
the manual force-sync endpoint skip locked spools. Usage tracker delta
tracking is unaffected. Users can re-enable AMS sync by setting
weight_locked to false.
When scheduling a print to "any printer" (model-based assignment),
users can now override the 3MF's original filament choices per slot.
The override dropdown shows compatible filaments loaded across all
printers of the selected model, filtered by type and nozzle (H2D).
The scheduler matches against overridden type/color instead of the
original 3MF values, preferring printers with exact color matches.
Backend:
- New GET /printers/available-filaments endpoint (aggregates loaded
filaments across printers of a model, includes extruder_id for
dual-nozzle nozzle-aware filtering)
- New filament_overrides JSON column on print_queue table
- Scheduler applies overrides before AMS mapping, clears tray_info_idx
on overridden slots so color matching takes priority
- Printer selection prefers printers with most override color matches
Frontend:
- New FilamentOverride component with per-slot override dropdowns
- Type-filtered options (PLA slots only show PLA)
- Nozzle-aware filtering (H2D: only shows filaments on correct extruder)
- Integrated into PrintModal for model-based queue mode
Tests:
- 11 backend unit tests (color match counting, override application)
- 12 frontend tests (rendering, type/nozzle filtering, interactions)
i18n: All 6 locales (en, de, fr, it, ja, pt-BR)
SpoolBuddy turns a Raspberry Pi 4B with a PN5180 NFC reader and
NAU7802 scale into a filament management station that integrates
with Bambuddy via REST API and WebSocket.
Backend: SpoolBuddyDevice model, 10 REST endpoints (/spoolbuddy/*),
6 WebSocket broadcast types, background offline-detection watchdog.
RPi daemon: asyncio service with concurrent NFC polling (300ms,
MIFARE Classic + Bambu HKDF key derivation), scale reading (10 SPS,
5-sample moving average, stability detection), and 10s heartbeat
with exponential backoff reconnect.
Frontend: kiosk-optimized 1024x600 UI at /spoolbuddy with Dashboard
(live weight + NFC spool detection), AMS Overview, Inventory,
Printers, and Settings pages. useSpoolBuddyState reducer hook
driven by WebSocket CustomEvents.
i18n: all 6 locales (en, de, fr, it, ja, pt-BR).
Multiple Virtual Printers:
- Each VP gets a dedicated bind IP with independent FTP, MQTT, SSDP, and Bind services
- New VirtualPrinter DB model, CRUD API (/api/virtual-printers), React UI
- VirtualPrinterList, VirtualPrinterCard, VirtualPrinterAddDialog components
- Per-instance TLS certificates (shared CA), 11 printer models, all 4 modes
- Auto-incremented serial suffixes, network interface override per VP
Dual Bind/Detect Ports (#445):
- Listen on both ports 3000 and 3002 for slicer bind/detect handshake
- Different BambuStudio/OrcaSlicer versions use different ports
- Applies to BindServer (server mode) and SlicerProxyManager (proxy mode)
- Updated Dockerfile, docker-compose.yml, firewall rules in wiki
Also:
- Rewrote VP test suite for new multi-instance architecture (75 tests)
- Rewritten "How it works" section with 3-step workflow explanation
- Updated all 5 locales (en, de, ja, fr, it)
- Updated wiki and website for multi-VP + dual ports
- New multi-VP screenshot
Add a new `printers:clear_plate` permission so admins can grant
plate-clearing ability without full `printers:control` access.
Existing groups with `printers:control` automatically receive the
new permission on startup via migration.
Replace the cramped permission modal in Settings with a dedicated
full-page group editor (`/groups/new`, `/groups/:id/edit`) featuring
search filtering, select all/clear all, category-level toggles,
and a responsive 2-column permission grid. Remove dead GroupsPage
code that was never routed.
- Backend: new Permission enum, category, defaults, endpoint guard, migration
- Frontend: GroupEditPage, updated routes, removed modal from SettingsPage
- Tests: 10 backend + 10 frontend tests for new permission and editor
- Docs: updated wiki (auth, printer-control, API), website, changelog
- i18n: added group editor keys to all 6 locale files (en/de/ja/fr/pt-BR/it)
Add a chronological, table-based print log as a 4th view mode in the
Archives page. Log entries are stored in a separate print_log_entries
table — clearing the log never touches archives or queue items.
Backend:
- New PrintLogEntry model with independent table
- GET /print-log/ endpoint with search, printer, user, status, date filters
- DELETE /print-log/ clears only log entries
- Thumbnail serving endpoint for log entries
- write_log_entry() service called on print completion
- Auth: ARCHIVES_READ for viewing, ARCHIVES_DELETE_ALL for clearing
Frontend:
- New 'log' ViewMode with ClipboardList icon toggle
- Filterable/searchable table with pagination (10/25/50/100 rows)
- Colored status badges, duration formatting, filament color swatches
- Clear button with confirmation modal
- All filter state persisted to localStorage
- i18n: EN, DE, JA, FR, IT translations
Notify users when the print bed cools below a configurable threshold
(default 35°C) after a print finishes, so they know when to remove parts.
- Backend: DB migration, model, schemas, notification template, service
method, background cooldown monitor (polls every 15s, 30min timeout)
- Frontend: event toggle in provider card/modal, threshold setting in
Settings > Notifications, i18n keys for all 5 locales
- Tests: 4 backend + 4 frontend tests
- Docs: README, website, wiki updated
Dual-nozzle H2D/H2D Pro: filament matching now respects nozzle assignments
from the 3MF file. Each AMS unit feeds a specific nozzle (L/R), and the
scheduler/frontend constrain matching to only trays on the correct nozzle.
Falls back to unfiltered matching when no trays exist on the target nozzle.
L/R badges shown in the filament mapping UI. Translated in en/de/ja/it.
Fix AMS slot config overwritten on startup: on_ams_change unconditionally
unlinked BL spool assignments on every MQTT pushall, then re-assigned them
sending ams_filament_setting without setting_id — clearing the printer's
filament preset. Now compares spool RFID identifiers before unlinking.
Fix BL spool detection false positives: removed tray_info_idx from detection
logic in both backend is_bambu_lab_spool() and frontend isBambuLabSpool().
Third-party spools using Bambu generic presets had GF-prefixed tray_info_idx
values, causing misidentification. Now uses only tray_uuid and tag_uid.
SQLite WAL mode with 5s busy timeout reduces "database is locked" errors.
External links behind reverse proxies (Traefik, nginx) block iframe
embedding via X-Frame-Options/CSP headers. Add a per-link boolean
toggle so users can choose between iframe (default) and new-tab
behavior. Keyboard shortcuts also respect the setting.
Users who use OrcaSlicer without Bambu Cloud can now import slicer
presets directly into Bambuddy. Supports .orca_filament, .bbscfg,
.bbsflmt, .zip, and .json exports with automatic inheritance resolution
via OrcaSlicer's GitHub base profiles (cached with 7-day TTL).
Implement accurate per-filament usage tracking for Spoolman integration,
similar to OpenSpoolman v0.3.0. This replaces the previous single-spool
reporting with multi-material aware tracking.
Features:
- Parse G-code from 3MF files at print start to build per-layer,
per-filament cumulative extrusion maps
- Store tracking data in new `active_print_spoolman` database table
(survives server restarts for long prints)
- Report accurate partial usage when prints fail/cancel based on
actual layer progress and G-code data
- Add "Disable AMS Weight Sync" setting to prevent AMS percentage-based
weight estimates from overwriting Spoolman's granular tracking
- Add "Report Partial Usage for Failed Prints" toggle (only shown when
weight sync is disabled)
- Use Spoolman's filament density instead of defaults for mm-to-grams
conversion
- Prefer tray_uuid over tag_uid for spool identification
Features:
- Add location filter for "Any {Model}" queue assignments
- Queue items can target a specific location (e.g., "Any X1C in Workshop")
- Location dropdown filter on Queue page to view jobs by location
- Scheduler considers location when assigning model-based jobs
Closes#220
PR #215 claimed to fix this but the actual ALTER TABLE migration was
not included. Users upgrading from 0.1.6b11 to 0.1.6 still see:
"no such column: print_archives.sliced_for_model"
This commit adds the actual migration that was missing.
Closes#211
Backend:
- Split update/delete permissions into *_own and *_all variants:
- queue:update_own/all, queue:delete_own/all
- archives:update_own/all, archives:delete_own/all, archives:reprint_own/all
- library:update_own/all, library:delete_own/all
- Add require_ownership_permission dependency factory in auth.py
- Enforce ownership checks on all relevant API endpoints:
- archives.py: PATCH, DELETE, POST /reprint
- print_queue.py: PATCH, DELETE, POST /cancel, PATCH /bulk
- library.py: PUT /files, DELETE /files, POST /bulk-delete, DELETE /folders
- Add user items count endpoint: GET /users/{id}/items-count
- Add delete_items parameter to DELETE /users/{id}
- Explicitly set created_by_id to NULL on user deletion for DB portability
- Add permission migration for existing groups in database.py
- Add require_permission_if_auth_enabled for folder delete
Frontend:
- Add canModify helper to AuthContext for ownership-based checks
- Update ArchivesPage: use canModify for edit/delete/reprint buttons
- Update QueuePage: use canModify for edit/delete/cancel buttons
- Update FileManagerPage: use canModify for edit/delete buttons
- Update SettingsPage: add user deletion modal with item handling options
- Update StatsPage: use archives:update_all for recalculate costs
- Update Permission type with new ownership permissions
- Add getUserItemsCount and update deleteUser API methods
Tests:
- Add test_ownership_permissions.py with 28 comprehensive tests
- Test admin *_all permissions, operator *_own permissions
- Test bulk operations skip non-owned items
- Test auth disabled allows all operations
- Test user deletion with/without items
Closes#205
Track and display who performs key actions in Bambuddy:
- Archives: who uploaded each archive file
- Library: who uploaded each file in File Manager
- Queue: who added each print job to the queue
- Printers: who started the current print (reprint tracking)
Backend changes:
- Add created_by_id column to print_archives, library_files, print_queue tables
- Add database migrations for new columns (auto-run on startup)
- Update archive, library, and queue routes to capture current user
- Add current-print-user endpoint for printer reprint tracking
- Track reprint user in PrinterManager in-memory state
- Fix file uploads not sending auth headers (FormData requires explicit headers)
Frontend changes:
- Display username on archive cards, library files, queue items
- Show "Started by" on printer cards during active prints
- Add auth headers to all 12 FormData upload functions
- Update TypeScript types for user tracking fields
Tests:
- Add unit tests for PrinterManager user tracking methods (7 tests)
- Add integration tests for current-print-user endpoint (3 tests)
- Add integration tests for library file user tracking (3 tests)
Works when authentication is enabled; gracefully hidden when disabled.
Closes#206
Library files now store paths relative to base_dir instead of absolute
paths. This ensures thumbnails and files work correctly after restoring
a backup on a different system or with a different data directory.
Changes:
- Add to_relative_path() and to_absolute_path() helper functions
- Update file upload, ZIP extraction, and STL thumbnail generation
to store relative paths
- Update download, thumbnail, gcode, and delete endpoints to resolve
relative paths when accessing files
- Add database migration to convert existing absolute paths to relative
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The code is ready for testing. After pushing to the remote host:
1. The migration will run automatically on startup, converting any existing absolute paths
2. New files will be stored with relative paths
3. Thumbnails should display correctly after backup/restore
Replace the complex JSON-based backup system (~2000 lines) with a simple
approach that copies the SQLite database and all data directories into a
single ZIP file.
Backend changes:
- Add close_all_connections() and reinitialize_database() helpers to database.py
- New GET /backup endpoint: creates complete ZIP with bambuddy.db and all
data directories (archive, virtual_printer, plate_calibration, icons, projects)
- New POST /restore endpoint: extracts ZIP, replaces database and directories,
requires restart after restore
- Move legacy endpoints to /backup-legacy and /restore-legacy for transition
Frontend changes:
- Simplify api.exportBackup() - no longer takes category parameters
- Simplify api.importBackup() - no longer takes overwrite parameter
- Remove BackupModal and RestoreModal components from GitHubBackupSettings
- Add simple Download/Restore buttons with inline logic
- Add blocking modal overlay during backup/restore operations
- Add beforeunload handler to prevent accidental navigation
- Show operation status messages during backup/restore
Benefits:
- ~100 lines vs ~2000 lines of backup/restore code
- Complete by definition - SQLite database contains ALL data
- No code changes needed when schema changes
- No ID remapping required - IDs stay the same
- Faster - file copy vs querying all tables
These columns were added in 0.1.6 beta but migrations were missing:
- nozzle_count: Integer DEFAULT 1 (for dual-extruder detection)
- print_hours_offset: Float DEFAULT 0.0 (baseline hours adjustment)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add migration for target_model, required_filament_types, and waiting_reason
columns in print_queue table. These columns were added to the model for the
model-based queue assignment feature but the migration was missing.
