New Features

• Missing Spool Assignment Notification (#763) — When a print starts and the AMS mapping references tray slots without assigned spools, Bambuddy now shows a warning toast in the frontend and can send push notifications via any configured notification provider. The notification includes the printer name, missing slot labels (e.g. A2, Ext-L), and expected material profile. A new "Missing Spool Assignment" toggle is available under Print Events in notification provider settings (off by default). Fully integrated with i18n (all 7 locales). Contributed by @Keybored02.
• Mid-Print Spool Reassignment Tracking (#763) — Usage tracking now correctly handles spool changes during a print. If a spool assignment is changed after a print starts, the system uses the live assignment for filament deduction; otherwise it falls back to the snapshot taken at print start. This ensures accurate filament tracking even when swapping spools mid-print. Contributed by @Keybored02.
• Auto-Link Untagged Inventory Spools on AMS Insert (#538) — When a Bambu Lab spool is inserted into the AMS and no existing tag match is found, the system now checks if there is an untagged inventory spool with the same material, subtype, and color. If found, the RFID tag is automatically linked to that existing spool instead of creating a duplicate entry. Uses FIFO ordering (oldest spool first) so spools are consumed in purchase order. Matching is case-insensitive. Requested by @wreuel.
• External Folder Mounting for File Manager (#124) — Host directories (NAS shares, USB drives, network storage) can now be mounted into the File Manager without copying files. Click "Link External" to point at a Docker bind-mounted path. Files are indexed into the database on scan but accessed directly from their original location — nothing is copied. Supports read-only mode (default, blocks uploads/moves/deletes), hidden file filtering, and automatic thumbnail extraction for 3MF, STL, gcode, and image files. External folders show a distinct icon and info bar with a rescan button. Deleting an external folder only removes the database index, never the actual files. Requested by @S1N4X.

Fixed

• SpoolBuddy Update Check Always Shows "Up to Date" — The SpoolBuddy daemon update check compared the device's firmware version against GitHub releases instead of the running Bambuddy backend version. This meant the check could incorrectly report "up to date" even when the daemon was behind. Fixed by comparing directly against APP_VERSION from the backend config.
• SpoolBuddy Updates Now Use SSH — Replaced the fragile self-update mechanism (daemon pulls its own code via git, permission errors on .git/, hardcoded main branch) with SSH-based updates driven by the Bambuddy backend. Bambuddy now SSHes into the SpoolBuddy Pi and runs git fetch/checkout, pip install, systemctl restart, and kiosk browser restart remotely. Updates automatically use the same branch as Bambuddy. SSH key pairing is fully automatic — Bambuddy generates an ED25519 keypair and includes the public key in the device registration response; the daemon deploys it to authorized_keys on first connect. The install script creates the spoolbuddy user with a bash shell and sudoers entries for daemon and kiosk restart. A "Force Update" button allows re-deploying even when versions match. The SSH public key is also shown in SpoolBuddy Settings → Updates → SSH Setup for manual pairing if needed.
• Frontend Not Updating After Deploy — The service worker used stale-while-revalidate for JS/CSS assets, serving the old cached bundle even after a new build was deployed. Changed to network-first for JS/CSS (Vite content-hashes filenames so cache-busting is built in), bumped SW cache version, and added Cache-Control: no-cache to the sw.js endpoint so browsers always pick up new service worker versions immediately. The SpoolBuddy kiosk now skips SW registration entirely and unregisters any existing SW — a touchscreen kiosk has no use for offline caching and it was the main source of stale frontend issues after updates.
• SpoolBuddy Kiosk Starts Before Network Is Ready — On fresh installs, the kiosk browser launched before the network was fully up, showing a connection error for 10-15 seconds until connectivity was restored. The getty@tty1 autologin override now waits for network-online.target so Chromium has connectivity when it starts.
• SpoolBuddy Update UI Stale After Restart — After a SpoolBuddy update, the UI permanently showed the old version and "update available" because: (1) the SSH update set status to "complete" after the daemon had already re-registered, overwriting the cleared state; (2) the kiosk restart navigated away from the updates page; (3) query cache served stale data. Fixed by letting daemon re-registration clear all update status, removing the kiosk restart in favor of a frontend-driven window.location.reload() triggered via WebSocket when the daemon comes back online, and adding proper loading states to Check/Force Update buttons.
• Virtual Printer Proxy A1 Printing Fails (#757) — BambuStudio could not send prints to A1 (and potentially P1S) virtual printers in proxy mode. The slicer connects to undocumented proprietary ports 2024-2026 on these models, which the proxy was not forwarding, causing BambuStudio to show an access code dialog instead of printing. Added transparent TCP pass-through proxying for ports 2024-2026. These ports are silently ignored on models that don't use them (X1C, H2C, P2S). Reported by @Utility9298.
• Spool Assignment on Empty AMS Slots (#784) — Empty AMS slots (no physical spool detected) showed "Assign Spool" and "Configure" buttons in the hover popup. Assigning a spool to an empty slot created a stuck state because no "Unassign" button is available for empty slots. Truly empty slots now hide both buttons, while slots with a spool inserted but filament not loaded still show configure/assign. Also fixed stale AMS slot data on H2D and other printers that only send {id, state} in incremental MQTT updates — filament load/unload transitions now update in real-time without requiring a reconnect. Reported by @RosdasHH.
• Log Flood: "State is FINISH but completion NOT triggered" (#790) — A diagnostic log message introduced in 0.2.2.1 fired on every MQTT update while a printer sat in FINISH or FAILED state, flooding logs with thousands of lines per minute in printer farms. Fixed by only logging once on the initial state transition. Reported by @user.
• ffmpeg Process Leak Causing Memory Growth (#776) — Camera stream ffmpeg processes accumulated over time, consuming several GB of RAM. When a user closed the camera viewer, the frontend sent a stop signal that killed the ffmpeg process, but the backend stream generator interpreted the dead process as a dropped connection and respawned ffmpeg — up to 30 reconnection attempts per stream. The orphan cleanup couldn't catch these because they were tracked as "active". Fixed by signaling the generator's disconnect event from the stop endpoint before killing the process, checking for stream removal before reconnecting, and tracking frame timestamps per-stream instead of per-printer so stale detection works correctly when multiple streams exist. Reported by @ChrisTheDBA, confirmed by @peter-k-de.
