New Features

• Queue Timeline View (#823) — The queue page now has a production schedule view showing when each print is estimated to finish. Events are sorted chronologically and grouped by hour, with cards showing the file name, printer, estimated completion time, and time remaining. Active prints show a live progress bar. Filter by "Show All", "Printing", or "Queued", and navigate between days. Click any event to edit or stop it. Toggle between List and Timeline views with the button group above the queue. Requested by sanjay2409.
• Staggered Batch Start for Multi-Printer Jobs (#752) — When sending a print to multiple printers via the queue, you can now stagger the starts to avoid power spikes from simultaneous bed heating. Enable "Stagger printer starts" in the schedule options to define a group size (how many printers start at once) and interval (minutes between groups). For example, 10 printers with group size 2 and interval 5 min will start in 5 waves over 25 minutes. Default group size and interval are configurable in Settings → Queue. Works with both ASAP and Scheduled timing — ASAP starts the first group immediately, subsequent groups get computed scheduled times. The stagger option is also available in the direct Print dialog when multiple printers are selected — prints are automatically queued with staggered start times, so you can close the browser and walk away. Requested by UVCXanth.
• Plate-Clear Confirmation Setting (#752) — New "Require plate-clear confirmation" toggle in Settings → Queue. When disabled, the scheduler starts queued prints automatically on printers with finished jobs without waiting for per-printer plate confirmation. Useful for farm workflows where plates are verified physically before starting a batch. Default is enabled (existing behavior preserved). Requested by UVCXanth.
• Settings Queue Tab — New dedicated Queue tab in Settings consolidates queue-related settings: staggered start defaults and auto-drying configuration (moved from the Filament tab).
• Per-User Statistics Filtering (#730) — Admins can now filter the Statistics page by user. A user dropdown appears in the stats header for users with the new stats:filter_by_user permission (Administrators only by default). Filter by a specific user to see their prints, filament usage, and costs, or select "No User (System)" to view prints without user attribution (e.g. slicer-initiated or pre-auth prints). The filter applies to all stats widgets and exports. Requested by 3823u44238.
• Bulk Printer Actions (#825) — Select multiple printer cards and apply bulk actions from a floating toolbar. Toggle selection mode from the header, then click cards to select. Use "Select All", "Select by State" (printing, paused, finished, idle, error, offline), or "Select by Location" to quickly pick printers. Available actions: Stop, Pause, Resume, Clear Notifications, and Clear Bed — each button is smart-enabled based on the selected printers' current states. Confirmation modals for destructive actions (Stop, Pause, Clear Bed). The status summary bar now shows all printer states (printing, paused, finished, idle, error, offline). Requested by therevoman.
• Prefer Lowest Remaining Filament (#805) — New optional setting in Settings → Filament that prefers AMS spools with the lowest remaining filament during auto-matching. When multiple spools match the same type and color, the one with the least filament remaining is selected first. Helps consume partial spools before starting new ones. Applies to queue scheduling, print modal, and multi-printer mapping. Unknown remain values (e.g. external spools without sensors) are treated as full. Disabled by default. Requested by Mofoss.

Improved

• Queue Page Visual Refresh — Compact stats bar replaces the five summary cards (saves vertical space), color-coded left borders on all queue items for instant status scanning, collapsible history section (collapsed by default), and condensed single-line rows for history items showing more prints at a glance.

Fixed

• External Spool Print Fails on P1S/P1P Without AMS (#854) — Sending a print job to a printer with no AMS units and only an external spool (virtual tray 254) caused the printer to reject the command with "Failed to get AMS mapping table". The print command was sent with use_ams: true (the default), but firmware on printers without AMS hardware rejects that combination. Now automatically sets use_ams: false when all filament slots map to external spools or are unmapped. H2D-series printers are excluded since they use use_ams for nozzle routing. Reported by UVCXanth.
• External Folder Scan 500 Error on 3MF Files (#846) — Scanning an external folder containing .3mf files crashed with "Object of type bytes is not JSON serializable". The parsed 3MF metadata contained raw thumbnail bytes (_thumbnail_data) that were stored directly in the database JSON column without cleaning. Also removed a call to the non-existent parser.extract_thumbnail() method — thumbnail data is already available in the parsed metadata. Now uses the same clean_metadata() pattern as upload and zip extraction. Reported by SMAW.
• Archives Capped at 50 Items (#843) — The archives page only showed the 50 most recent prints due to a hardcoded API limit. Users with more than 50 archives could not see or access older entries. Fixed by fetching all archives and adding client-side pagination with configurable page sizes (25, 50, 100, 200, or All). Page size preference is persisted. Reported by dcbaldwin.
• Filament Usage Not Recorded When Auto-Archive Disabled — When a printer had "Auto-archive completed prints" turned off, filament consumption was silently lost. The on_print_complete callback returned early before reaching the usage tracking code, so neither the internal inventory (AMS remain% deltas) nor Spoolman received usage data. Moved filament tracking to run before the archive check so usage is always recorded regardless of the auto-archive setting.
• H2D External Spool Uses Wrong Nozzle (#836) — Prints sent from Bambuddy to dual-nozzle printers (H2D, H2D Pro) with external spools always routed to the wrong nozzle. The old ams_mapping2 format used a shared ams_id: 255 with slot_id: 0/1 to differentiate external slots, but the firmware interpreted slot_id as the nozzle index (0=main/right, 1=deputy/left), routing filament to the opposite nozzle. Already fixed by the #797 ams_mapping2 format change (per-tray ams_id instead of shared unit), but users on older builds still experience this. Printing the same file directly from the slicer worked correctly. Reported by NoahTingey.
• SpoolBuddy "Add to Inventory" Failed Silently — The quick-add button on the SpoolBuddy kiosk did nothing when tapped. The scale weight was sent as a float but the backend requires an integer, causing a Pydantic validation error. The error was silently caught with no user feedback, leaving the confirmation modal stuck open. Fixed by rounding the weight before sending, moving the modal close to a finally block, and adding an error toast with the actual API message.
• SpoolBuddy Dashboard Crash on Null Spool Fields — Viewing a spool with null subtype, brand, rgba, or color_name on the SpoolBuddy dashboard crashed the UI (black screen). The spool prop construction used displayedSpool?.subtype ?? sbState.matchedSpool!.subtype — when the field was null, the ?? operator fell through to sbState.matchedSpool which could also be null, causing a TypeError. Fixed by picking one source object instead of mixing per-field fallbacks. Added a global React error boundary so future crashes show the error instead of a black screen.
• Plate Thumbnails 401 in Print Modal — Multi-plate 3MF plate thumbnails in the print modal returned 401 Unauthorized when authentication was enabled. The backend returns bare URL paths for plate thumbnails, but the PlateSelector component used them directly in <img src> without appending the stream token. Fixed by passing the URL through withStreamToken().
• Schedule Calendar Picker Opens Off-Screen — Clicking the calendar icon in the print modal's scheduled mode opened the native date picker at the bottom of the viewport instead of near the date field. The hidden datetime-local input used sr-only positioning which anchored the picker off-screen. Fixed by positioning the hidden input inside the date field's container.
• SpoolBuddy Kiosk Display Blanking and Crashes — The kiosk Chromium flags added in 0.2.2.2 caused display instability: --js-flags=--max-old-space-size=128 crashed the V8 renderer when heap exceeded 128 MB, --enable-low-end-device-mode aggressively killed GPU rendering surfaces, and resetting CHROMIUM_FLAGS discarded the Pi's GPU defaults (--enable-gpu-rasterization, ANGLE/GLES) creating an unstable mixed CPU/GPU rendering path. Fixed by removing both flags, appending kiosk flags to Pi defaults instead of replacing them, adding a wlr-randr keep-alive loop to prevent display blanking, and adding <screenBlankTimeout>0</screenBlankTimeout> to the labwc config.
