**# Bambuddy v0.2.2**
**## Highlights**
- **Remote AMS Drying** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — Start, monitor, and stop drying sessions for AMS 2 Pro and AMS-HT directly from the Printers page. Select filament type with official BambuStudio temperature/duration presets, or set temperature manually. Supported on X1/X1C, P1P/P1S, H2D, H2D Pro, and X1E.
- **Queue Auto-Drying** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — Automatically dry filament between scheduled queue prints when AMS humidity exceeds the configured threshold. Uses conservative parameters for mixed filament types, with optional "block queue" mode to delay prints until drying completes.
- **Ambient Drying** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — Automatically keep filament dry on idle printers based on humidity, even without queued prints. Enable "Ambient drying" in Settings → Print Queue.
- **Virtual Printer Queue Auto-Dispatch Toggle** ([#587](https://github.com/maziggy/bambuddy/issues/587)) — Added an "Auto-dispatch" toggle to virtual printers in Queue mode. When disabled, prints are added to the queue but wait for manual dispatch instead of starting automatically.
- **Queue All Plates** ([#530](https://github.com/maziggy/bambuddy/issues/530)) — Multi-plate 3MF files can now be queued in one action. A "Queue All N Plates" toggle adds every plate as a separate queue entry, each individually editable.
- **AMS Info Card & Custom Labels** ([#570](https://github.com/maziggy/bambuddy/pull/570)) — Hovering an AMS label shows serial number, firmware version, and an editable friendly name. Slot numbers now display inside each filament color circle. Contributed by @cadtoolbox.
- **In-App Bug Reporting** — A floating bug report button lets users submit reports directly from the UI, including description, optional screenshot, and automatically collected diagnostic data with full sensitive-data redaction.
**## New Features**
- **First Layer Complete Notification** ([#679](https://github.com/maziggy/bambuddy/issues/679)) — Get notified with a camera snapshot when the first layer finishes printing, so you can check adhesion remotely. Enable the "First Layer Complete" toggle on any notification provider.
- **Remote AMS Drying** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — Start, monitor, and stop drying sessions for AMS 2 Pro and AMS-HT directly from the Printers page. Select filament type with official BambuStudio temperature/duration presets, or set temperature manually. Supported on X1/X1C, P1P/P1S, H2D, H2D Pro, and X1E.
- **Queue Auto-Drying** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — Automatically dry filament between scheduled queue prints when AMS humidity exceeds the configured threshold. Uses conservative parameters for mixed filament types, with optional "block queue" mode to delay prints until drying completes.
- **Configurable Drying Presets** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — Customize temperature and duration for each filament type in Settings → Print Queue. Defaults match BambuStudio presets, with separate presets for AMS 2 Pro and AMS-HT.
- **AMS PSU Detection** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — The drying button is disabled with a tooltip when the AMS lacks sufficient power for drying. Reads `dry_sf_reason` from firmware and surfaces HMS error codes for power issues.
- **Ambient Drying** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — Automatically keep filament dry on idle printers based on humidity, even without queued prints. Enable "Ambient drying" in Settings → Print Queue.
- **Assign Spool to Empty AMS Slot** ([#717](https://github.com/maziggy/bambuddy/issues/717)) — The "Assign Spool" option now appears on empty (unconfigured) AMS slots. Selecting a spool auto-configures the slot with the correct filament profile, color, and K-profile in one step.
- **Home Assistant Notification Provider** ([#656](https://github.com/maziggy/bambuddy/issues/656)) — Send persistent notifications to the HA dashboard. HA automations can forward them to mobile apps, WhatsApp, or any other service.
- **Virtual Printer Queue Auto-Dispatch Toggle** ([#587](https://github.com/maziggy/bambuddy/issues/587)) — Added an "Auto-dispatch" toggle to virtual printers in Queue mode. When disabled, prints are added to the queue but wait for manual dispatch instead of starting automatically.
- **Queue All Plates** ([#530](https://github.com/maziggy/bambuddy/issues/530)) — Multi-plate 3MF files can now be queued in one action. A "Queue All N Plates" toggle adds every plate as a separate queue entry, each individually editable.
- **Malaysian Ringgit Currency** ([#634](https://github.com/maziggy/bambuddy/issues/634)) — Added MYR (RM) to the list of supported currencies for filament cost tracking.
- **ETA Variable in Notifications** ([#638](https://github.com/maziggy/bambuddy/issues/638)) — Added `{eta}` template variable to print start/progress notifications. Shows estimated wall-clock completion time based on the user's configured time format (12h/24h).
- **Bulk Delete Spool and Color Catalog Entries** ([#646](https://github.com/maziggy/bambuddy/issues/646)) — Added checkbox selection and bulk delete to both the Spool Catalog and Color Catalog in Settings > Filament.
- **Force Color Match** ([#625](https://github.com/maziggy/bambuddy/pull/625)) — Added a "Force Color Match" option for "Print to Any" queue scheduling, requiring strict color matching when assigning prints to printers. Contributed by @cadtoolbox.
- **Israeli New Shekel Currency** — Added ILS to the list of supported currencies for filament cost tracking.
- **AMS Info Card & Custom Labels** ([#570](https://github.com/maziggy/bambuddy/pull/570)) — Hovering an AMS label shows serial number, firmware version, and an editable friendly name. Slot numbers now display inside each filament color circle. Contributed by @cadtoolbox.
- **In-App Bug Reporting** — A floating bug report button lets users submit reports directly from the UI, including description, optional screenshot, and automatically collected diagnostic data with full sensitive-data redaction.
- **SpoolBuddy NFC Tag Writing (OpenTag3D)** — Write NFC tags for third-party filament spools using the OpenTag3D format on NTAG213/215/216 stickers. Supports writing for existing spools, creating new spools, or replacing damaged tags.
- **SpoolBuddy On-Screen Keyboard** — Added a virtual QWERTY keyboard for the SpoolBuddy kiosk UI since the Raspberry Pi has no physical keyboard. Auto-shows when text inputs are focused.
- **SpoolBuddy Inline Spool Cards** — Placing an NFC-tagged spool on the reader now shows spool info directly in the dashboard panel instead of a modal overlay, with action buttons for AMS assignment, weight sync, and more.
- **SpoolBuddy AMS Page: External Slots & Slot Configuration** — The SpoolBuddy AMS page now displays external spool slots and AMS-HT units. Clicking any slot opens the configuration modal for filament type and color.
- **SpoolBuddy Dashboard Redesign** — Redesigned with a two-column layout showing device connection status and printer badges on the left, spool card on the right. Removed the separate inventory page in favor of main Bambuddy UI.
- **SpoolBuddy Kiosk Auth Bypass via API Key** — The `/auth/me` endpoint now accepts API keys, and the install script includes the API key in the kiosk URL for automatic authentication on boot.
- **Daily Beta Builds** — Added a release script for daily multi-arch Docker beta builds pushed to GHCR and Docker Hub. Beta images are never tagged as `latest`.
- **Inventory Scale Weight Check Column** — Added a "Weight Check" column (hidden by default) to the inventory table that compares each spool's last scale measurement against its calculated gross weight.
**## Fixed**
- **Library Upload Doesn't Show New File Until Page Reload** ([#704](https://github.com/maziggy/bambuddy/issues/704)) — The upload endpoint used `db.flush()` instead of `db.commit()`, so the file list was stale until page reload. Fixed the same race condition in folder create/update and file update endpoints.
- **Printer File Manager Doesn't Auto-Refresh** ([#704](https://github.com/maziggy/bambuddy/issues/704)) — The printer SD card browser only fetched files once when opened. Now auto-refreshes every 30 seconds.
- **Database Connection Pool Exhaustion Under Load** ([#704](https://github.com/maziggy/bambuddy/issues/704)) — Background tasks held database sessions during slow network I/O, exhausting the pool. Doubled the pool to 30 connections.
- **Block Mode Skips Humidity Auto-Stop** ([#292](https://github.com/maziggy/bambuddy/issues/292)) — When "Wait for drying to complete" was enabled, drying sessions that reached humidity target continued indefinitely. Block mode now only prevents starting new drying, not stopping completed sessions.
- **AMS Fill Level Shows 0% for Non-Viewer Users** ([#676](https://github.com/maziggy/bambuddy/issues/676)) — Stale inventory fill of 0% permanently shadowed the correct real-time AMS remain value due to nullish coalescing not falling through on `0`. Now bypasses inventory when it says 0% but AMS hardware reports positive remain.
- **Virtual Printer Proxy Mode Always Shows X1C Model** — Now auto-inherits the model from the target printer when creating or updating a proxy virtual printer.
- **Cloud Profiles Shared Across All Users** ([#665](https://github.com/maziggy/bambuddy/issues/665)) — Bambu Cloud credentials were stored globally instead of per-user. Each user now logs into their own Cloud account independently. Also fixed cloud endpoints requiring wrong permissions.
- **Local Profiles Not Shown in AMS Slot Configuration** — The `compatible_printers` filter parsed JSON as semicolon-delimited, silently skipping all local presets. Removed the filter entirely.
- **Interface Aliases Not Shown in Virtual Printer Interface Select** — Interface aliases (e.g. `eth0:1`) were invisible because the Docker image lacked `iproute2`. Added it to the image.
- **P2S Camera Stream Disconnects After a Few Seconds** ([#661](https://github.com/maziggy/bambuddy/issues/661)) — GnuTLS rejected TLS behaviors some printer firmwares rely on. Added a local TLS termination proxy using OpenSSL. Also reduced reconnect delay and fixed choppy external camera streams.
- **iOS/iPadOS Cannot Reposition Floating Camera** ([#687](https://github.com/maziggy/bambuddy/issues/687)) — The floating camera viewer only handled mouse events. Added touch event support for drag and resize.
- **PA-CF / PA12-CF / PAHT-CF Not Treated as Compatible** ([#688](https://github.com/maziggy/bambuddy/issues/688)) — Added a filament type equivalence system so PA variants are treated as compatible in scheduler assignment, AMS slot matching, and filament override dropdowns.
- **Force Color Match Toggle Click Target Too Large** ([#688](https://github.com/maziggy/bambuddy/issues/688)) — The click target now covers only the checkbox, icon, and label text instead of the entire row.
- **HA Switch Badge Always Sends Turn On Instead of Toggle** — Now sends `toggle` for non-script entities so the badge click actually toggles the switch state.
- **Multiple Plugs Per Printer Crashes Auto-On/Off** — `scalar_one_or_none()` raised `MultipleResultsFound` when multiple smart plugs were assigned. Now fetches all plugs and returns the main power plug.
- **Multiple HA Switches Per Printer UNIQUE Constraint** — The migration to remove the UNIQUE constraint on `smart_plugs.printer_id` now uses regex matching and also checks standalone UNIQUE indexes.
- **HMS Notifications for Unknown/Phantom Error Codes** — Flipped notification logic from "notify all, suppress specific" to "only notify for errors with known descriptions", matching the frontend behavior.
- **Ethernet Badge Shown on WiFi Printers / MQTT Disconnecting** ([#585](https://github.com/maziggy/bambuddy/issues/585)) — Three bugs: wrong detection method (bit 18 vs wifi_signal heuristic), bad import path crashing MQTT thread, and WiFi-only models not excluded.
- **Inventory Usage Tracker Missing External Spool Mapping** ([#677](https://github.com/maziggy/bambuddy/issues/677)) — Fallback `slot_id - 1` could never reach external spool IDs. Added position-based resolution using sorted available tray IDs. Contributed by @shrunbr.
- **Spool Assignment Applies Wrong Filament Profile** ([#681](https://github.com/maziggy/bambuddy/issues/681)) — Cloud API returns only the base `filament_id` for versioned setting IDs, ignoring variants. Added a cross-check that corrects the filament ID via reverse lookup.
- **Debug Logging Endpoint 500 Error** — Duration calculation mixed timezone-aware and naive datetimes. Now strips timezone info when reading stored timestamps.
- **Bed Cooled Notification Never Fires** ([#497](https://github.com/maziggy/bambuddy/issues/497)) — Partial MQTT updates didn't include `bed_temper`, so cached temperature never dropped. The monitor now sends periodic `pushall` commands to force fresh data.
- **Notification Provider Missing Event Toggles on Create** ([#497](https://github.com/maziggy/bambuddy/issues/497)) — The create endpoint omitted 8 event toggles (`on_bed_cooled` and 7 queue events), so they always defaulted to false regardless of user selection.
- **Clear Plate Prompt Shown for Staged Queue Items** — The prompt now only appears when there are auto-dispatchable items that the scheduler will actually start.
- **Ethernet Badge Shown on WiFi-Only Printers** ([#585](https://github.com/maziggy/bambuddy/issues/585)) — WiFi-only models (A1, P1P, etc.) are now excluded via model-based gating.
- **GitHub Backup Required Cloud Login** ([#655](https://github.com/maziggy/bambuddy/issues/655)) — Removed the cloud auth gate so GitHub backup can be configured and used without Bambu Cloud login.
- **GitHub Backup Log Timestamps Off by 1 Hour** — Timestamps were displayed in UTC instead of the user's local timezone. Now uses `parseUTCDate` for correct conversion.
- **H2D AMS Units Shown on Wrong Nozzle** ([#659](https://github.com/maziggy/bambuddy/issues/659)) — Three bugs in AMS `info` field parsing: decimal instead of hex, wrong bit extraction, and partial updates overwriting full map. All fixed.
- **SD Card Error After FTP Upload** ([#645](https://github.com/maziggy/bambuddy/issues/645)) — The FTP upload skipped the server's 226 "Transfer complete" response, sending the print command before the file was flushed to disk. Now waits for confirmation.
- **P2S Shows Carbon Rod Maintenance Tasks** ([#640](https://github.com/maziggy/bambuddy/issues/640)) — The P2S uses steel shafts, not carbon rods. Added a new `steel_rod` category with appropriate maintenance tasks.
- **Dispatch Toast Stuck After Second Print** — The dedup guard was never reset between batches, leaving the progress toast stuck. Now resets on dismiss and new batch start.
- **Archive Card Buttons Overlapping at Narrow Widths** ([#641](https://github.com/maziggy/bambuddy/issues/641)) — Buttons now clip cleanly with ellipsis instead of overlapping at narrow viewport widths.
- **Debug Logging Banner Timer Shows Negative Time** — Mixed local/UTC timestamps caused negative duration display. Now stores and compares all timestamps in UTC.
- **Non-Bambu Lab Spools Can't Link/Unlink to Spoolman** ([#653](https://github.com/maziggy/bambuddy/pull/653)) — Generates a fallback tag from printer/AMS/tray IDs for spools without RFID identifiers. Also added an "Unlink" button. Contributed by @shrunbr.
- **Spoolman Location Not Updated on Link/Unlink** ([#669](https://github.com/maziggy/bambuddy/pull/669)) — Linking now sets the Spoolman location to printer name, AMS name, and slot number; unlinking clears it. Contributed by @shrunbr.
- **Print Dispatch Toast Disappears Instantly on Fast Uploads** ([#615](https://github.com/maziggy/bambuddy/issues/615)) — The dispatch toast now stays visible for 3 seconds after completion showing a success message before auto-dismissing.
- **Print Modal Shows Busy Printers as Selectable** ([#622](https://github.com/maziggy/bambuddy/issues/622)) — The printer selector now shows live state badges and grays out busy printers in reprint mode. Queue mode still allows selecting busy printers.
- **PWA Install Not Available in Chrome** ([#629](https://github.com/maziggy/bambuddy/issues/629)) — Fixed incorrect icon dimensions, split the `"any maskable"` purpose, and added required screenshots to the manifest.
- **Project Statistics Count Archived Files as Printed** ([#630](https://github.com/maziggy/bambuddy/issues/630)) — Only files with `status="completed"` (actually printed) now count toward completion stats, excluding archived files.
- **Python 3.10 Compatibility** — Added a compatibility shim for `enum.StrEnum` which was added in Python 3.11.
- **Bug Report Bubble Overlapping Toasts** — Moved toast notifications and upload progress above the bug report bubble.
- **Virtual Printer: Bind-TLS Proxy Handshake Failure on OpenSSL 3.x** — Added RSA key exchange ciphers to the client SSL context for compatibility with Bambu printers.
- **Windows: Server Shuts Down After 60 Seconds** ([#605](https://github.com/maziggy/bambuddy/issues/605)) — ffmpeg cleanup broadcast `CTRL_C_EVENT` to the entire process group. Now spawns ffmpeg in its own process group.
- **Multi-Printer Filament Mapping Shows Wrong Nozzle Filaments on Dual-Nozzle Printers** ([#624](https://github.com/maziggy/bambuddy/issues/624)) — The multi-printer filament mapping path was missing the `nozzle_id` filter that the single-printer path already had.
- **Filament Mapping Dropdowns Missing Subtypes** ([#624](https://github.com/maziggy/bambuddy/issues/624)) — Now shows `tray_sub_brands` (e.g. "PLA Basic", "PLA Matte") in all filament dropdowns, with separate dedup entries for different subtypes.
- **Archive Card Shows "Source" Badge for Sliced .3mf Files** — Now checks `total_layers` and `print_time_seconds` metadata to determine if a `.3mf` file is sliced. Also passes the original filename when creating archives.
- **AMS Slot Shows Wrong Material for "Support for" Profiles** — The name parser returned the first material match ("PLA") instead of the one after "Support for" ("PETG"). Both frontend and backend parsers now detect the naming pattern.
- **Firmware Check Shows Wrong Version for H2D Pro** ([#584](https://github.com/maziggy/bambuddy/issues/584)) — Added all known SSDP model codes to the firmware check mapping so raw device codes resolve to the correct firmware track.
- **Spurious Error Notifications During Normal Printing (0300_0002)** — HMS error codes with low 16 bits below `0x4000` are status indicators, not faults. Now skips them in both parsers.
- **Spool Auto-Assign Fails With Greenlet Error** ([#612](https://github.com/maziggy/bambuddy/issues/612)) — SQLAlchemy lazy-loaded `spool.assignments` outside the async greenlet. Now initializes the collection on new spools and eagerly loads it for existing ones.
- **SpoolBuddy Link Tag Missing tag_type** — Now uses the dedicated `linkTagToSpool` endpoint with proper `tag_type` and `data_origin` values.
- **SpoolBuddy AMS Page Missing Fill Levels for Non-BL Spools** — Now fetches inventory assignments and computes fill levels from weight data, falling back to AMS remain when no assignment exists.
- **SpoolBuddy AMS Page Ext-R Slot Falsely Shown as Active When Idle** — Guards against `tray_now=255` (idle sentinel) before ext slot active check.
- **Printer Card Loses Info When Print Is Paused** ([#562](https://github.com/maziggy/bambuddy/issues/562)) — Print progress info now shows for both `RUNNING` and `PAUSE` states. Status label correctly reads "Paused".
- **SpoolBuddy "Assign to AMS" Slot Shows Empty Fields in Slicer** — Fixed version suffix handling in cloud API calls, correct `filament_id` resolution, and `SlotPresetMapping` saving.
- **Virtual Printer Bind Server Fails With TLS-Enabled Slicers** ([#559](https://github.com/maziggy/bambuddy/issues/559)) — Port 3002 now uses TLS for slicer compatibility, while port 3000 remains plain TCP.
- **Queue Returns 500 When Cancelled Print Exists** ([#558](https://github.com/maziggy/bambuddy/issues/558)) — Normalizes `"aborted"` status to `"cancelled"` before storing. A startup fixup converts existing bad rows.
- **Tests Send Real Maintenance Notifications** — Tests now cancel spawned background tasks before mock context exits.
- **Virtual Printer Config Changes Ignored Until Toggle Off/On** — `sync_from_db()` now compares critical fields and restarts VPs when config changes are detected.
- **Sidebar Navigation Ignores User Permissions** — Each nav item is now hidden when the user lacks the corresponding read permission. Also added missing `inventory:*` permissions to the frontend type definition.
- **Camera Button Clickable Without Permission & ffmpeg Process Leak** ([#550](https://github.com/maziggy/bambuddy/issues/550)) — Camera button now requires `camera:view` permission. Added proper process cleanup with background disconnect monitoring and periodic orphan scanning.
- **Windows Install Fails With "Syntax of the Command Is Incorrect"** ([#544](https://github.com/maziggy/bambuddy/issues/544)) — Removed redundant hash verification block that used unparseable multi-line `for /f` syntax.
- **Queue Badge Shows on Incompatible Printers** ([#486](https://github.com/maziggy/bambuddy/issues/486)) — The badge count now applies the same filament compatibility filter as the queue widget.
- **SpoolBuddy Daemon Can't Find Hardware Drivers** — Added `scripts/` to `sys.path` at daemon startup and moved imports inside try/except blocks. Demoted hardware-not-available logs to INFO.
- **SpoolBuddy Scale Tare & Calibration Not Applied** — Fixed five bugs in the tare/calibration chain including missing API endpoints, stale values overwriting new ones, and self-referential factor computation.
- **A1 Mini Shows "Unknown" Status After MQTT Payload Decode Failure** ([#549](https://github.com/maziggy/bambuddy/issues/549)) — Non-UTF-8 MQTT payloads now fall back to `decode(errors="replace")` instead of being silently dropped.
- **H2C Dual Nozzle Variant (O1C2) Not Recognized** ([#489](https://github.com/maziggy/bambuddy/issues/489)) — Added `O1C2` to all model ID maps across backend and frontend, fixing camera protocol, display names, and more.
- **Support Package Leaks Full Subnet IPs and Misdetects Docker Network Mode** — Masks subnet octets, correctly detects Docker network mode, and parses `fun` field from top-level MQTT payload.
- **SpoolBuddy Scale Calibration Lost After Reboot** — Device ID generation now sorts network interfaces alphabetically for deterministic selection across reboots.
- **SpoolBuddy NFC Reader Fails to Detect Tags** — Fixed PN5180 polling state corruption with full hardware reset before each idle poll, and RF cycle before each active poll. Added auto-recovery after consecutive errors.
**## Improved**
- **Shorter Inventory Location Labels** — Location column now shows compact labels like "H2D-1 B3" instead of "H2D-1 AMS-B Slot 3".
- **Higher FTP Timeout Options for Large Files** ([#660](https://github.com/maziggy/bambuddy/issues/660)) — Added 180s and 300s FTP timeout options. The previous 120s max was insufficient for large 3MF files during active printing.
- **Separate Permission for AMS Spool Assignments** ([#635](https://github.com/maziggy/bambuddy/issues/635)) — New `inventory:view_assignments` permission lets users see AMS spool assignments without accessing the full Inventory page.
- **Prometheus Build Info Metric** ([#633](https://github.com/maziggy/bambuddy/pull/633)) — Added `bambuddy_build_info` gauge metric exposing version, Python version, platform, and architecture. Contributed by @sw1nn.
- **i18n: Settings, Smart Plugs, Notifications, Backup/Restore** — Replaced all hardcoded English strings with translation keys across Settings, Smart Plug, Notification, and Backup/Restore components. Added ~600 new keys to all 7 locales.
- **Install Script: Branch Selection** — The native install script now supports a `--branch` option and interactive branch prompt for beta testers.
- **Print Queue Scheduler Diagnostics** ([#616](https://github.com/maziggy/bambuddy/issues/616)) — Added diagnostic logging showing skip summaries and per-printer state details to help diagnose why queued prints aren't starting.
- **SpoolBuddy Settings Page Redesign** — Redesigned with a tabbed layout (Device, Display, Scale, Updates) including brightness slider, screen blank timeout, step-indicator calibration wizard, and update checker.
- **SpoolBuddy Language & Time Format Support** — The kiosk now respects Bambuddy's configured UI language and time format, with full translations for all 6 languages.
- **SpoolBuddy Kiosk Stability** — Disabled swipe-to-navigate gesture and added `video` group for DSI backlight access.
- **SpoolBuddy Touch-Friendly UI** — Enlarged all interactive elements across the kiosk UI for comfortable finger use on the 1024×600 touchscreen, meeting 44px minimum tap targets.
- **Ethernet Connection Indicator** ([#585](https://github.com/maziggy/bambuddy/issues/585)) — Printers on ethernet now show a green "Ethernet" badge with cable icon instead of WiFi signal strength.
- **SpoolBuddy AMS Page Single-Slot Card Layout** — AMS-HT and external spool cards now use a responsive grid aligned with regular AMS card columns.
- **SpoolBuddy Scale Value Stabilization** — Suppresses redundant scale reports (only sends on ≥2g change), increased moving average window, and added frontend 3g display threshold.
- **SpoolBuddy TopBar: Online Printer Selection** — Printer selector now only shows online printers and auto-selects the first available. Auto-switches if selected printer goes offline.
- **SpoolBuddy Assign to AMS Redesign** — Full-screen overlay reusing AMS page components with one-click slot assignment via a single API call.
- **Filament ID Conversion Utility** — Extracted filament_id/setting_id conversion into a shared utility. The `assign_spool` endpoint now correctly sends both `tray_info_idx` and `setting_id`.
- **Updates Card Separates Firmware and Software Settings** — Split into labeled "Printer Firmware" and "Bambuddy Software" sections.
- **SpoolBuddy Test Coverage** — Added 21 backend integration tests and 20 frontend component tests covering all SpoolBuddy API endpoints and main components.
- **Cleanup Obsolete Settings** — Startup migration now deletes orphaned settings keys no longer used by the application.
- **Added HUF Currency** ([#579](https://github.com/maziggy/bambuddy/issues/579)) — Added Hungarian Forint (HUF, Ft) to supported currencies.
- **FTP Upload Progress & Speed** — Reduced chunk size from 1MB to 64KB for smoother progress reporting. Removed post-upload wait that caused 30+ second hangs on H2D. Added transfer speed logging.
- **Wider Print & Schedule Modals** — Increased modal width from 512px to 672px to accommodate long filament profile names.
**## Changed**
- **CI: Node.js 20 → 22** — Updated GitHub Actions workflows to Node.js 22 LTS ahead of GitHub's Node 20 deprecation.
- **Daily Builds Falsely Trigger Update Notification** — The version parser misclassified daily build tags as full releases. Now strips the daily suffix before parsing.
- **License changed from MIT to AGPL-3.0** — To prevent unauthorized redistribution of Bambuddy as a closed-source product. Community contributions and usage are unaffected.
**## Security**
- **Stored XSS via Project Notes** — Project notes rendered with `dangerouslySetInnerHTML` without sanitization. Now sanitized with DOMPurify.
- **Stored XSS via 3MF Description (Sanitizer Bypass)** — Hand-rolled HTML sanitizer allowed attribute injection via quote break-out. Replaced with DOMPurify.
- **Unauthenticated Auth Toggle via Setup Endpoint** — The `/api/v1/auth/setup` endpoint could disable authentication without being authenticated. Now returns 403 when auth is already enabled.
- **PyJWT ≥2.12.0** — Bumped minimum version to address CVE-2026-32597.
- **flatted ≥3.4.0** — Updated transitive ESLint dependency to address GHSA-25h7-pfq9-p65f (unbounded recursion DoS).
- **Access Code Redacted from Support Logs** — Printer access codes in RTSP URLs were not redacted in support bundles. Extended sanitizer to cover `rtsps://` URLs and added access codes to exact-match redaction.

Previously the "Assign Spool" button only appeared on configured slots,
forcing users to manually configure first — redundant since assignment
auto-configures the slot. Now shows on empty slots too. Also fixed the
AMS hover card showing generic material type instead of the spool's
slicer preset name after assignment.
- Sanitize project notes with DOMPurify before rendering via
dangerouslySetInnerHTML (ProjectDetailPage.tsx)
- Replace hand-rolled HTML sanitizer with DOMPurify in ProjectPageModal
to prevent attribute injection via crafted 3MF href values
- Block /api/v1/auth/setup when auth is already enabled to prevent
unauthenticated clients from disabling authentication remotely
The Debian ffmpeg package uses GnuTLS, whose hardened defaults reject
TLS renegotiation and legacy ciphers that some Bambu printer firmwares
(notably P2S) rely on — causing RTSP sessions to drop after a few
seconds.
Add a local TLS termination proxy (Python ssl/OpenSSL) that handles
the TLS connection to the printer and exposes a plain RTSP port to
ffmpeg. The proxy rewrites RTSP request-line URLs (rtsp://proxy →
rtsps://printer) while preserving Authorization headers so Digest
auth hashes remain valid.
Also:
- Reduce RTSP reconnect delay from 1.0s to 0.2s
- Add ffmpeg fast-start flags (-probesize 32, -analyzeduration 0,
-fflags nobuffer, -flags low_delay)
- Fix external camera double rate-limiting causing choppy streams
- Apply TLS proxy to external camera rtsps:// URLs and snapshot capture
- Update orphan ffmpeg cleanup to match rtsp:// (proxied) URLs
- Add unit tests for RTSP URL rewriting and proxy lifecycle
The Bambu Cloud API returns the base filament_id for versioned
setting IDs (e.g. GFSL99 → GFL99 for all "Generic PLA" variants),
so assigning a spool with a specific variant like "Generic PLA Silk"
(GFSL99_01) would configure the AMS slot with the base "Generic PLA"
profile (GFL99) instead of the correct one (GFL96).
Added a post-resolution cross-check: if the resolved filament_id maps
to a different name than the spool's stored preset name, reverse-lookup
the correct filament_id from the built-in filament table.
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.
RTSP stream URLs (rtsps://bblp:<code>@<ip>:322/...) were not covered
by the credential sanitizer, leaking access codes in support bundles
and bug report logs. Extended the URL regex to match rtsps:// and added
access codes to the sensitive string collection for exact-match
redaction in both export paths.
Ambient drying: automatically dry filament on idle printers when
humidity exceeds threshold, regardless of queue state. Separate toggle
from queue auto-drying — both can run simultaneously. Uses the same
presets, humidity threshold, and power constraint detection.
Fix: block mode (wait for drying) previously skipped the humidity
auto-stop check for already-drying printers, causing drying to
continue indefinitely. Now only prevents starting new drying.
Queue auto-drying: scheduler automatically starts drying on idle printers
with scheduled queue prints when AMS humidity exceeds the configured
threshold. Uses conservative parameters (lowest temp, longest duration)
for mixed filaments. Drying stops when humidity drops below threshold
(30-minute minimum prevents oscillation), when scheduled items are
removed, or when the feature is disabled. Optional "block queue" mode
delays the next print until drying completes.
Configurable presets: temperature and duration per filament type,
editable in Settings → Print Queue, used by both manual drying popover
and queue auto-drying. Separate presets for AMS 2 Pro (n3f) and AMS-HT
(n3s) reflecting different heating capabilities.
PSU detection: drying button disabled with tooltip when dry_sf_reason
indicates insufficient power. Parses drying status bits and dry_sf_reason
from AMS info hex string via MQTT.
Backend: print_scheduler.py (+316 lines), bambu_mqtt.py, printer_manager,
schemas, settings route. Frontend: PrintersPage drying presets prop,
SettingsPage drying config UI, i18n (7 locales). Tests: 27 new tests in
test_scheduler_auto_drying.py covering conservative params, presets,
state sync, stop logic, minimum drying time, and auto-stop regressions.
Fix P2S camera stream dropping and snapshot capture race (#661)
P2S firmware's TLS renegotiation is rejected by Debian's hardened GnuTLS
defaults, causing ffmpeg RTSP sessions to drop after ~3 seconds. Add
GnuTLS config allowing unsafe renegotiation and legacy ciphers. Also add
ffmpeg fast-start flags, reduce reconnect delay from 1.0s to 0.2s,
remove double rate-limiting on external camera streams, and fix orphan
cleanup killing snapshot capture ffmpeg processes (exit code -9).
Or as a single combined commit:
Fix P2S camera streaming, snapshot race, and energy stats (#661, #695)
Camera: P2S firmware's TLS renegotiation rejected by Debian's hardened
GnuTLS defaults, dropping RTSP sessions after ~3s. Add GnuTLS compat
config, ffmpeg fast-start flags, reduce reconnect delay to 0.2s, remove
external camera double rate-limiting, and register snapshot ffmpeg PIDs
with the orphan tracker to prevent SIGKILL during capture.
In "total" energy tracking mode, the stats endpoint queried smart plug
lifetime counters which can't be filtered by date range. Energy costs
and kWh stayed the same regardless of timeframe selection. Fall back to
per-print archive data when date filters are active.
parse_version() misclassified "0.2.2b4-daily.20260313" as a release
because the daily suffix made the last dot-segment ("20260313") contain
no alpha chars, bypassing prerelease detection. Strip -daily.YYYYMMDD
suffix before parsing so daily builds compare as their base beta version.
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.
Printers send many undocumented HMS codes (e.g. 0501_0002, 0501_0004,
0300_0001) that don't correspond to real errors — calibration status,
firmware state, etc. The frontend already filters these out (only shows
codes in ERROR_DESCRIPTIONS), but the backend notified for all codes
with severity >= 2, causing spurious email/push notifications on every
backend restart when a printer has active phantom codes.
Flip the logic: only send notifications for HMS codes with a known
description in the backend's HMS_ERROR_DESCRIPTIONS dictionary. Also
fix the log message to report the actual number of notifications sent,
not the pre-filter count.
Non-script HA entities (switch/light/input_boolean) on the printer card
always sent turn_on when clicked, which is a no-op when the switch is
already on. Now sends toggle for non-script entities so the badge click
actually changes the switch state. Script entities still use turn_on.
Also fix SmartPlugManager._get_plug_for_printer() using
scalar_one_or_none() which crashes with MultipleResultsFound when
multiple plugs are assigned to the same printer (e.g., Tasmota + HA
switch). Now fetches all plugs and returns the main non-script plug.
Add tests for both fixes: _get_plug_for_printer multi-plug handling
(5 tests) and canonicalFilamentType/filamentTypesCompatible/autoMatch
PA-CF equivalence (8 tests).
Bambu Lab firmware treats PA-CF, PA12-CF, and PAHT-CF as interchangeable,
but the print scheduler and filament override UI used exact string matching.
A 3MF requiring PA-CF wouldn't match PA12-CF in the AMS, leaving the
override dropdown disabled and preventing scheduler assignment.
Add a filament type equivalence system (both backend and frontend) so
these PA variants are treated as compatible in scheduler assignment,
AMS slot matching, force color match validation, and the override dropdown.
Also fix the "Force color match" checkbox click target being too wide
(entire row instead of just the checkbox/label) by changing flex to
inline-flex on the label element.
The embedded camera viewer only handled mouse events (mousedown,
mousemove, mouseup) for window dragging and resizing. On iOS/iPadOS,
touch input doesn't trigger mouse events, so the camera window
couldn't be repositioned — touch just scrolled the page underneath.
Add touch event handlers (touchstart, touchmove, touchend, touchcancel)
alongside mouse handlers for both the header drag handle and the
bottom-right resize handle. Uses preventDefault on touchmove to
prevent page scrolling during drag.
When all higher-priority slot-to-tray mapping methods failed (MQTT
mapping, print command mapping, queue mapping, color matching), the
internal usage tracker fell back to slot_id - 1 which can never reach
external spool IDs (254/255) or AMS-HT IDs (128+). Added position-based
resolution using sorted available tray IDs, matching the Spoolman fix
from PR #686.
When inventory spool assignments had stale weight_used values, the fill
level fallback chain (Spoolman → Inventory → AMS remain) used nullish
coalescing (??), which doesn't fall through on 0. A stale inventory
fill of 0% permanently shadowed the correct real-time AMS remain value.
Viewer users were unaffected because their group lacked the
inventory:view_assignments permission, so the query never fired.
Now when inventory says 0% but AMS hardware reports positive remain,
the inventory value is bypassed in favor of the live AMS data.
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.
When creating a virtual printer in proxy mode, the model was always set
to X1C because the frontend hides the model dropdown and the backend
used a hardcoded default. Now auto-inherits the model from the target
printer in proxy mode — on create, on target printer change, and on
mode switch to proxy.
Start, monitor, and stop drying sessions for AMS 2 Pro (n3f) and
AMS-HT (n3s) directly from the Printers page. Flame icon in AMS card
header opens a popover with filament-based temperature/duration presets
from BambuStudio. Live countdown status bar shows time remaining.
Backend: cache module_type from MQTT get_version, expose dry_time and
module_type in both WebSocket and REST paths, add supports_drying()
with firmware gating, add server-side guard on start_drying endpoint.
Frontend: drying button, popover with filament select + temp/duration
sliders, status bar, start/stop mutations. i18n for all 7 locales.
Supported: X1/X1C (fw 01.09+), P1P/P1S (fw 01.08+), H2D (fw 01.02.30+),
H2D Pro, X1E. Not supported: P2S, A1, A1 Mini, H2S, H2C.
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.
The P2S firmware drops RTSP sessions after a few seconds with an I/O
error. The backend treated this as fatal, ending the MJPEG stream and
forcing the frontend through a full reconnection cycle. Added transparent
auto-reconnection: when ffmpeg's RTSP connection dies, it respawns
immediately and continues streaming MJPEG frames to the browser with
only a brief freeze (~1s). Up to 30 reconnections before giving up.
The Docker image (python:3.13-slim) didn't include iproute2, so the
`ip` command wasn't available. The code fell back to ioctl-based
enumeration which can only return one IP per interface — aliases like
eth0:1 were completely invisible. Added iproute2 to the Dockerfile.
The compatible_printers filter on local presets parsed the stored JSON
array (e.g. '["BBL X1C 0.4 nozzle"]') as a semicolon-delimited string,
so matching always failed and every local preset was silently skipped.
Removed the filter entirely — user-imported profiles should be usable
on any printer.
Three bugs: (1) home_flag bit 18 is set on all printers regardless
of connection type, so every ethernet-capable model showed the badge
even on WiFi. Replaced with wifi_signal heuristic — ethernet printers
with WiFi disabled report a hardcoded -90 dBm sentinel. (2) The lazy
import used `from app.utils.printer_models` which crashes with
ModuleNotFoundError in paho-mqtt's background thread (correct path:
backend.app.utils.printer_models). This killed the thread, causing
all printers to go stale after 60s and disconnect/reconnect in a
loop. (3) WiFi-only models excluded via model-based gating.
home_flag bit 18 is set on all printers regardless of hardware,
causing the ethernet badge to appear on WiFi-only models (A1, P1P,
etc.). The previous fix removed the feature entirely, so ethernet
printers lost their badge too.
Now only trusts bit 18 on models with an ethernet port (X1C, X1E,
P1S, P2S, H2D, H2D Pro, H2C, H2S). WiFi-only models always show
the WiFi signal badge.
The GET /api/v1/support/debug-logging endpoint returned 500 when the
database contained a timezone-aware enabled_at timestamp written by
0.2.2b3. The duration calculation mixed offset-aware and offset-naive
datetimes, raising TypeError. Strip tzinfo when reading the stored value.
