Replace fixed 30-second debug log collection with an interactive
3-step flow: start logging, reproduce the issue, stop & submit.
Users now control timing instead of racing a countdown.
Backend: split _collect_debug_logs() into POST /start-logging and
POST /stop-logging endpoints; add debug_logs field to submit request.
Frontend: 3-step progress indicator with elapsed timer, pulsing
active state, and 5-minute auto-stop. Updated all 7 locale files.
Add a "Rotate spool during drying" checkbox to the manual drying popover
for AMS 2 Pro and AMS-HT units. The firmware-level rotate_tray field was
already sent (hardcoded to false) — this makes it user-configurable.
The checkbox defaults to unchecked and resets each time the popover opens.
Firmware silently disables rotation if filament is currently loaded.
The closed-source bambu_networking DLL validates TLS connection parameters
and rejects connections where the certificate doesn't match the printer's
real BBL CA certificate. The TLS-terminating proxy presented Bambuddy's
own certificate, causing X1C/X1 prints to silently fail after verify_job.
Switch to transparent TCP proxying for FTP, FileTransfer, Camera, and FTP
data — only MQTT remains TLS-terminated (required for IP rewriting). The
slicer now gets end-to-end TLS directly with the printer's real certificate.
Changes:
- SlicerProxyManager uses TCPProxy for FTP (990), FileTransfer (6000),
Camera (322), and pre-listens on FTP data ports (50000-50100)
- Only MQTT (8883) uses TLSProxy for IP rewriting
- Remove debug logging from MQTT and FTP proxy code
- Fix install.sh missing AmbientCapabilities=CAP_NET_BIND_SERVICE
- Update module docstring, migration docs, README proxy description
- Add tests verifying transparent proxy architecture
Add a speed control badge to the printer monitoring card controls row
that lets users switch between Silent (50%), Standard (100%), Sport
(124%), and Ludicrous (166%) presets during active prints. The badge
displays a gauge icon with the current speed percentage, always visible
but disabled when idle. Includes backend endpoint, optimistic UI
updates, i18n for all 7 locales, and full test coverage.

- Update CHANGELOG and README
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.
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.
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.

Sends persistent notifications to the HA dashboard using the existing
HA connection from Settings. Zero config — just select "Home Assistant"
as provider type. Users can forward notifications to mobile via HA
automations.
Multi-plate 3MF files can now be queued in one action via a "Queue All
Plates" toggle in the plate selector (add-to-queue mode only). Each
plate becomes a separate queue entry, individually editable.
Fix: "Clear Plate & Start Next" no longer appears when all pending
queue items are staged (manual_start). The prompt only shows when
there are auto-dispatchable items the scheduler will actually start.
visibility into AMS spool assignments on printer cards without exposing
the full Inventory page (#635). The list_assignments endpoint now
requires this new permission instead of inventory:read. All default
groups (Administrators, Operators, Viewers) include it for backward
compatibility.
Closes#634
- Add 12 backend integration tests for AMS labels API (GET/PUT/DELETE,
serial resolution, synthetic key fallback, whitespace handling, validation)
- Add 10 frontend tests for FilamentSlotCircle component (rendering,
border styles, background colors, text contrast inversion)
- Fix ruff W293 trailing whitespace in inventory.py from contributor fix
- Add ams_label model import to test conftest.py
- Update CHANGELOG, README, website features page, and wiki AMS docs
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.
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)
Add Quick Add mode to the spool form for simplified entry (material +
color + weight only), and a quantity field (1-100) for creating multiple
identical spools at once. Stock spools (no slicer profile) are computed
rather than stored — any spool without slicer_filament shows an amber
"Stock" badge. New filter chips (All/Stock/Configured) on the inventory
page. Backend bulk endpoint creates N spools in one transaction.
Backend:
- SpoolBulkCreate schema with quantity validation (1-100)
- POST /inventory/spools/bulk endpoint
Frontend:
- Quick Add toggle in SpoolFormModal (create mode only)
- Quantity field in FilamentSection (both modes)
- bulkCreateSpools API method and bulkCreateMutation
- Stock column (hidden by default) and stock filter chips
- Inline error rendering moved into FilamentSection
- CellCtx extended with t() for translatable cell content
Tests:
- 13 backend tests (schema validation + endpoint logic)
- 10 frontend tests (validateForm quickAdd + UI behavior)
i18n: 6 locales (en, de, fr, it, ja, pt-BR)

This allows users sending particularly large prints to slow printers such as the P1-series to start a print and then move onto another task in Bambuddy immediately (such as starting more prints on more printers). It also gives the user visibility into what's happening instead of a loading indicator appearing for an indefinite period of time.
The new toast-based UI uses websockets to update in real time. It will also appear for other users / instances of Bambuddy, not just the user who started the prints, allowing more transparency and handling cases where the user closes the page and then comes back wanting to know the status of the dispatching.

When the auto-scan attached the wrong timelapse (e.g. from a different
print), there was no way to fix it — the file couldn't be removed and
re-scanning was disabled once a timelapse was attached.
Add a "Clear Errors" button to the HMS error modal that sends
clean_print_error via MQTT and locally clears hms_errors for
immediate UI feedback. Useful for dismissing stale print_error
values that persist after print cancellation or transient events.
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
Backend:
- Add dual external spool support for H2D (vt_tray as list: Ext-L/Ext-R)
- Add cloud filament ID map endpoint (/cloud/filament-id-map)
- Fix RFID spool data erased by periodic AMS updates (skip tag matcher
for RFID-tagged trays)
- Fix AMS slot config overwrites RFID spool state
- Fix K-profile selection corrupts existing profiles on X1C/P1S
- Resolve K-profiles filament name via cloud filament ID map
- Update print scheduler and usage tracker for dual external spools
Frontend:
- Add printer model filtering to ConfigureAmsSlotModal (cloud/local/builtin
presets filtered by @BBL model suffix and compatible_printers)
- Add pre-population for configured slots (preset, color, K-profile)
- Add K-Profiles view with accurate filament name resolution
- Internationalize all ConfigureAmsSlotModal strings (en/de/fr/it/ja — 21 keys)
- Add 5 new ConfigureAmsSlotModal tests (model filtering, pre-selection,
color pre-population, i18n)
- Update PrintersPage for dual external spool rendering
Docs:
- Update CHANGELOG, README, website features, and wiki AMS docs
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.
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.
The print scheduler previously treated FINISH/FAILED as idle states
and would auto-start the next queued print before the user cleared
the build plate. Now requires explicit user confirmation via a
"Clear Plate & Start Next" button on the printer card. Uses an
in-memory plate-cleared flag — no MQTT command needed since the
scheduler's start_print overrides the printer state.
- Show firmware version badge on printer card (green=up to date,
orange=update available) with click to view release notes or
start update workflow
- Badge only shown when firmware checking is enabled in settings
- Modal adapts: info-only view when up to date (release notes
auto-expanded), update workflow when update available
- Gate badge query with firmware:read permission, upload button
with firmware:update permission
The remote_interface_ip setting only worked in proxy mode but was
completely ignored in server modes (immediate/review/print_queue).
Users with multiple NICs (LAN + Tailscale, Docker bridges) got wrong
auto-detected IP in SSDP broadcasts and TLS certificates.
Users can now choose their preferred slicer (Bambu Studio or OrcaSlicer)
in Settings → General. All "Open in Slicer" buttons across Archives,
3D Preview, and context menus use the correct protocol for the selected
slicer. OrcaSlicer uses orcaslicer://open?file=<URL> on all platforms;
Bambu Studio uses bambustudio:// (Windows) or bambustudioopen:// (macOS/
Linux). Default remains Bambu Studio for backward compatibility.
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).
The Add Printer dialog previously required users to manually enter their
network subnet for scanning (defaulting to 192.168.1.0/24). Now the
backend detects available network interfaces and returns their subnets
via the /discovery/info endpoint. The frontend auto-selects the first
detected subnet and shows a dropdown when multiple subnets are available,
falling back to a text input if none are detected.
AMS Lite units (A1 series) have no weight sensor and always report 0%
fill level. When a spool is linked to Spoolman with weight data, use
Spoolman's remaining weight as a fallback. External spools also show
fill level from Spoolman data instead of always showing unknown.
Backend: Enrich GET /spoolman/spools/linked response with
remaining_weight and filament_weight alongside spool ID.
Frontend: Add getSpoolmanFillLevel() helper. Update regular AMS, HT
AMS, and external spool fill computations to use Spoolman fallback
when AMS reports 0%. Show "(Spoolman)" indicator in hover card when
fill data comes from Spoolman.
