- Show all 6 nozzles including mounted: backend includes all nozzle_info
entries (removes id >= 2 filter), frontend filters to non-empty
- Translate nozzle type codes to full names: HS→Hardened Steel, 00/01/05
mapped to Stainless Steel/Hardened Steel/Tungsten Carbide
- Add flow type to hover card: HH→High Flow, HS→Standard
- Show filament material type in hover card (PLA, PETG etc.) from MQTT
tray_type/filament_type field
- Add filament_type to NozzleRackSlot schema (backend + frontend)
- Add translations (en, de, ja, it): nozzleTungstenCarbide, nozzleFlow,
nozzleHighFlow, nozzleStandardFlow
Timelapse: Replace mtime-based "most recent file" approach with a
snapshot-diff strategy — baseline existing MP4 filenames before waiting,
then detect the new file that appears after encoding. Fixes wrong
timelapse in LAN-only mode where printer clock is unsynchronized.
Falls back to print-name matching if no new file appears after retries.
Calibration: Skip archiving internal printer files under /usr/ (e.g.
/usr/etc/print/auto_cali_for_user.gcode) so calibration prints don't
appear in the archive.
The cover image cache was keyed by subtask_name and never invalidated
between prints. When a user printed the same project name twice with a
different bed layout, the cached thumbnail from the first print was
returned instead of fetching the new one from the printer.
Clear the cover cache for the printer on every print start so the next
cover request downloads a fresh 3MF and extracts the current thumbnail.
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.
H2C was mapped to the "h2d" firmware API key, causing it to check
the H2D firmware page and offer H2D firmware for download. H2C has
its own separate firmware track (01.01.x.x vs H2D's 01.02.x.x).
Changed H2C to use its own "h2c" API key and added the reverse
mapping. Also added missing H2C (O1C) and H2S (O1S) entries to
the printer model ID and 3MF model name maps.
The nozzle_info MQTT array contains L/R nozzle heads (IDs 0, 1) and
rack slots (IDs 16-21). Backend was dumping all entries into nozzle_rack,
and frontend slice(0,6) grabbed L, R, plus only 4 rack slots — cutting
off the last position (e.g. the 0.6mm nozzle) and showing the mounted
nozzle as docked.
Backend: filter nozzle_rack to id >= 2 (rack-only), sort by ID.
Frontend: compact single-row layout with bottom accent bars for
mounted/docked status, wider rack card (flex-[2]), vertically
centered temp cards.

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).
Capture 4 additional fields from MQTT nozzle data (max_temp, serial_number,
filament_color, filament_id) and surface them through REST/WebSocket APIs.
Add per-slot hover popover to the NozzleRackCard showing all metrics, filament
color backgrounds on slots, and i18n labels in all 4 locales.
The H2C printer has a tool-changer with a 6-nozzle rack, but
device.nozzle.info entries beyond index 1 were being dropped due to a
hardcoded 2-nozzle limit. This adds full nozzle rack storage, API
exposure, and a frontend card showing all dock positions.
This might fix (#58) getting uploads from the linux version of the
BambuStudio network plugin. Issue observer is connection resets with
larger uploads (somewhere >80k).
Large 3MF uploads intermittently failed with [Errno 104] Connection
reset by peer while the 16-byte verify_job always succeeded. The
_handle_data_connection callback returned immediately, letting the
asyncio task complete while cmd_STOR was still reading from the data
connection. The passive port listener also stayed open during transfers.
- Keep _handle_data_connection alive via _transfer_done event so the
asyncio task holds strong references throughout the transfer
- Close passive port listener after accepting the data connection
- Reject duplicate data connections with a warning log
- Add drain timeout (5s) to MQTT status pushes to prevent blocking
when the slicer is busy with FTP upload
- Improve error logging with bytes received and exception type
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.
H2D Pro firmware interprets use_ams as a nozzle index when sent as
integer (1 = deputy nozzle) instead of boolean. Bambu Studio sends
use_ams: true (boolean) while using integers for calibration fields.
Bambuddy was converting all boolean fields to integers for H2D series,
routing filament to the deputy nozzle instead of main, causing
extrusion motor overload at ~75% print completion.
Keep use_ams as boolean for all printers, matching Bambu Studio format.
Implements retry mechanism to handle intermittent network errors when
fetching spools cache for AMS sync operations.
Changes:
- Add retry logic to get_spools() with 3 attempts and 500ms delay
- Configure httpx client with connection pool limits to prevent stale
connection reuse (max_keepalive_connections=5, keepalive_expiry=30s)
- Recreate client on connection errors (ReadError, RemoteProtocolError)
- Abort sync operations if cache fetch fails after all retries
- Update on_ams_change, sync_single_printer, and sync_all_printers to
handle cache fetch failures gracefully
This addresses ReadError(ClosedResourceError()) failures that occurred
intermittently when Spoolman closed idle connections or connection
pooling reused stale connections.
Testing:
- Added 4 new unit tests for retry behavior
- All 1018 tests passing
- Add cached_spools parameter to find_spool_by_tag, find_spools_by_location_prefix, sync_ams_tray, and clear_location_for_removed_spools
- Fetch spools once before loops in on_ams_change, sync_single_printer, and sync_all_printers endpoints
- Cache newly created spools during sync to avoid duplicate API calls
- Add 5 unit tests for caching functionality (all passing)
- Reduce redundant API calls when syncing multiple AMS trays
- Improve sync performance for users with large spool databases
- Maintain backward compatibility with optional cached_spools parameters
- Add HA_URL and HA_TOKEN environment variables for automatic HA
integration configuration in HA add-on deployments
- Environment variables always override database settings with
non-negotiable precedence; database values preserved for fallback
- Auto-enable integration when both env vars are set; partial config
(one env var) uses database enable state without auto-enabling
- Add centralized get_homeassistant_settings() function following
Spoolman pattern; replace direct database queries across codebase
- Add ha_url_from_env, ha_token_from_env, ha_env_managed fields to
AppSettings schema to inform frontend about configuration source
- UI shows read-only fields with lock icons and "(Environment Managed)"
labels when env-controlled; toggle shows auto-enable badge
- Add comprehensive test coverage: 9 integration + 8 unit tests
Closes#283
Users with local DNS can now add printers using hostnames like
printer.local or my-printer.home.lan. Updated backend schema
validation, database column width, frontend form patterns/placeholders,
and i18n labels across all locales. Added integration tests for
hostname and FQDN creation plus invalid hostname rejection.
Enable Bambu Studio on a remote network to print through BamBuddy
acting as a TLS-terminating proxy for both MQTT and FTP connections.
- Add TLSProxy base class and FTPTLSProxy with PASV response rewriting,
EPSV→PASV translation, PROT P/C tracking, and one-shot data proxies
- Add SlicerProxyManager to coordinate per-slicer MQTT + FTP proxy pairs
- Support additional SAN IPs in certificate generation for proxy mode
- Broadcast SSDP on LAN B so slicers discover the proxy as a printer
- Narrow FTP passive port range to 50000-50100 with retry logic
- Expose proxy ports (8883, 9990, 50000-50100) in Dockerfile
- Document passive port range in docker-compose.yml

homeassistant_service.get_energy() was called without first configuring
the service with the HA URL and token, so it returned None for all
Home Assistant smart plugs. Added configure() call before the plug
loop, matching the pattern used in main.py and smart_plugs.py.
download_to_file() returned True when retrbinary transferred 0 bytes
without raising an exception. This caused the /cover endpoint to hit
the empty file check and raise HTTP 500 instead of retrying or
returning 404.
Now treats 0-byte downloads as failures, allowing the cover endpoint's
retry logic to work and falling back to 404 if all attempts fail.
The CodeQL cleanup in "Housekeeping" (2b11efd) bulk-narrowed except
clauses across 50+ files, breaking FTP uploads on ALL printer models.
ftplib.error_perm (550 errors) is not a subclass of ftplib.error_reply,
so diagnose_storage() CWD failures escaped the handler and prevented
STOR from ever executing — causing 100% upload failure and HTTP 500s
on /api/v1/archives/{id}/reprint and /api/v1/library/files/{id}/print.
FTP fixes:
- Remove diagnose_storage() from upload hot path
- Change all except (OSError, ftplib.error_reply) to
except (OSError, ftplib.Error) across bambu_ftp.py
Exception handling reverts (9 files):
- Revert narrowed except clauses back to except Exception in route
handlers and service code where broad catches are intentional
defensive programming (archive parsing, HTTP clients, 3MF/ZIP
processing, Home Assistant, firmware checks)
- Keep narrow exceptions only where safe (single-op blocks like
int(), file.unlink(), socket.close())
- Remove unused XMLParseError imports from archive.py, threemf_tools.py
Version system:
- Add 4-segment version support (e.g. 0.1.8.1) for patch releases
- Bump version to 0.1.8.1

Several FTP operations (file browser, timelapse scan, storage info,
cover download, skip objects, etc.) were missing the printer_model
parameter. Without it, A1/A1 Mini and PS1 printers can't use the prot_p/prot_c
auto-detection and fallback logic, causing FTP failures on these models
when the mode cache isn't already populated.
Simplify always-true authEnabled ternary and localSettings truthiness
checks in SettingsPage.tsx. Remove commented-out auth re-setup guard
and its dead _existing_setting/_user_count queries from auth.py.
Add clarifying comments to firmware_check.py api_key logs (model
identifier, not a secret).
