SpoolBuddy devices can now be updated from Settings → Updates without
SSH access. The daemon picks up an "update" command via its existing
heartbeat, runs git fetch/reset + pip install, reports progress back
to the backend, then exits for systemd to restart with the new code.
Backend: update_status/update_message fields, trigger + status endpoints
Daemon: _perform_update() handler, report_update_status() API method
Frontend: "Apply Update" button with live progress in UpdatesTab
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.
Carbon rods use plain bearings — lubricating them degrades print quality.
Removed the lubrication task from defaults; only "Clean Carbon Rods"
remains. Existing entries are auto-removed on next startup via
ensure_default_types(). Updated wiki link mapping and tests.
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.
After assigning a spool to an AMS slot, the Bambuddy UI could show the
wrong filament preset (e.g. "Bambu PLA Matte" instead of "Bambu PLA
Silk") even though the printer was configured correctly.
Two bugs:
1. AssignSpoolModal (PrintersPage hover card path) never saved the slot
preset mapping to the DB, so the display fell back to the old/stale
mapping from a previous manual configuration.
2. AssignToAmsModal (SpoolBuddy path) constructed the preset name from
spool.material + spool.subtype ("PLA Silk") instead of using the
authoritative spool.slicer_filament_name ("Bambu PLA Silk").
Fix: the backend now saves the slot preset mapping in assign_spool()
after successful MQTT configuration, using slicer_filament_name as the
display name. This covers both frontend paths and ensures the correct
name is always stored.
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.
Daily beta build tags (e.g. v0.2.3b1-daily.20260316) were not detected
as prereleases because parse_version() only checked the last
dot-separated segment for letters. The daily date suffix is purely
numeric, so it passed the stable release check. Now checks the entire
version string for prerelease markers.
- 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.
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.
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.
Two bugs prevented bed cooldown notifications from working:
1. Stale temperature data: After print completion, the printer sends
partial MQTT updates without bed_temper, leaving the cached value
frozen at the end-of-print temperature. The monitor polled for 30
minutes seeing the stale value above threshold, then timed out.
Fix: send periodic pushall commands to force fresh temperature data.
2. Missing fields in provider create endpoint: on_bed_cooled and all 7
queue event toggles were omitted from the NotificationProvider
constructor, silently discarding user selections on create (update
worked fine via dynamic setattr).
Also added debug logging to the bed cooldown polling loop.
The debug logging banner displayed a negative elapsed time (e.g. "-60m -59s")
equal to the server's UTC offset. datetime.now() stored local time without a
timezone indicator, but the frontend's parseUTCDate() interpreted it as UTC.
Use datetime.now(tz=timezone.utc) consistently for storing, parsing, and
comparing the enabled_at timestamp.

datetimes, raising TypeError. Strip tzinfo when reading the stored value.
* Expanded link logic to accept a generic spool tag (spool_tag, tray_uuid, or tag_uid) and validate 16/32-char hex values, including rejection of all-zero tags. Added a new unlink endpoint that clears Spoolman extra.tag for a given spool ID.
* Updated the link validation expectation to match the new 16-or-32-hex rule. Added an integration test for the new unlink endpoint to verify extra.tag is cleared and success is returned.
* Updated the link API call to send spool_tag instead of tray_uuid. Added a new unlinkSpool API helper that calls the new backend unlink route.
* Switched modal data source from inventory spools to Spoolman unlinked spools so the list matches the backend response you shared. Updated the link action to call Spoolman link directly and use trayUuid or tagUid as the slot tag.
* Refactored Spoolman card behavior so actions render correctly across linked/unlinked cases, and added support for an Unlink from Spoolman button under Open in Spoolman. Final UI rule now hides Unlink for Bambu Lab filament and shows it only for non-Bambu linked spools.
* Added fallback slot-tag generation so untagged slots can still be linked/unlinked reliably and linked spool lookups work consistently across AMS, AMS-HT, and external trays. Wired a new unlink mutation and passed per-slot unlink callbacks into the hover card, with query invalidation for linked/unlinked spool caches after unlink.
* Added/updated the noTrayUuid message to reflect that either tray UUID or tag UID is required when no slot tag is available. This keeps error text aligned with the new tag fallback and modal behavior.
* Added noTrayUuid message in the other languages. The translation was done using Google Translate.
* Updated LinkSpoolModal tests to use Spoolman API instead of inventory API, with new UnlinkedSpool data structure and Select Spool UI text.
* Adds hashSerialToHex32, uses new function in getFallbackSpoolTag and updates all uses. This ensures we're generating a fallback spool tag using the printers serial number rather than the database ID for consistency.
* Removes 'import json' from unlink_spool and moves to the top of the file.
* Removes hasUnlinkedSpools and related references since it's no longer used
* Removes noTrayUuid from translations and references in components.
* Adds confirmation dialog before fully unlinking spool from Spoolman
* Adds unlinkConfrimTitle and unlinkConfirmMessage. All languages other than English were done using Google Translate
* Fixes unlink toast to use dedicated unlinkSuccess and unlinkFailed keys.
* Changes tag priority on spoolTag, fixes type error by adding non-null assertion to spoolTag
* Switches around tag_uid and tray_uuid on const trayTag

The debug logging banner displayed a negative elapsed time (e.g. "-60m -59s")
equal to the server's UTC offset. datetime.now() stored local time without a
timezone indicator, but the frontend's parseUTCDate() interpreted it as UTC.
Use datetime.now(tz=timezone.utc) consistently for storing, parsing, and
comparing the enabled_at timestamp.
home_flag bit 18 was incorrectly interpreted as "wired/ethernet
connection", causing the ethernet badge to always show — even on
printers without an ethernet port (e.g. A1, P1S). This hid the
WiFi signal indicator entirely.
Removed the wired_network field and ethernet badge UI. The WiFi
signal badge now shows correctly whenever the printer reports
signal strength.
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.
Checkbox selection + "Delete Selected" button in Settings > Filament
for both Spool Catalog and Color Catalog. Adds POST bulk-delete
endpoints and translations for all 7 locales.
P2S uses hardened steel rods, not carbon fiber. Move P2S from
carbon rod classification to new steel_rod category with its own
"Lubricate Steel Rods" / "Clean Steel Rods" maintenance tasks.
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
