Spoolman server​

• Serve a Spoolman-compatible v1 API so Klipper front-ends (Mainsail / Fluidd) can read, consume and now fully manage your inventory: create / update / delete spools, filaments and vendors, plus /use weight/length reporting
• Settings toggle to enable it, with copy-to-clipboard for the base URL

Streaming overlay​

• Embeddable OBS / kiosk streaming overlay per printer (camera + live status), with query options for camera, status-bar position and background
• "Streaming overlay" entry point from the camera card

Calibration​

• Pressure-advance / linear-advance pattern (line) generator — the Sineos/Ellis method, complementing the existing tuning-tower ramp; each row prints a slow → fast → slow line at a stepped PA value so you pick the cleanest one
• "Read the guide" links to Andrew Ellis' Print Tuning Guide from the pressure-advance, retraction, flow and first-layer tests

Quality of life​

• Undo-on-delete across the whole app — spools, queues, printers, filament profiles, tags, backups, KB articles, screenshots, scheduled events, library files, CRM customers, orders and AI jobs (backups and screenshots previously deleted on a single click with no confirmation)
• Sidebar quick-search to jump to any panel, plus a "Pinned" section for favourite panels
• A "What's new" modal (now with a navbar button to reopen it), keyboard-shortcut help, compact-density toggle, "continue where you left off", persisted inventory filters, sticky table headers, dialog auto-focus and copy-to-clipboard helpers

Accessibility​

• Accessible names on icon-only buttons, focus trap and focus restore for dialogs, and a focusable skip-link
• WCAG AA contrast (axe-core audited): raised muted-text contrast and darker text variants for accent colours used as text, while surfaces keep the brand colour

Bambu Cloud & camera​

• Authenticator-app 2FA (TOTP) login with the real error surfaced; auto-fill LAN IP for cloud-imported Bambu printers; discovery no longer hangs
• RTSP transcode preserves aspect ratio; the REC badge shows the selected resolution

Fixes for features that silently did nothing​

• Smart ETA now actually learns — the slicer-vs-actual recorder was never wired into print completion
• Input Shaper Wizard accepts real Klipper resonance CSVs (the parser expected the wrong column names)
• Camera usage analytics and filament estimate-vs-actual accuracy are recorded — the writers were never called

Maintenance​

• Delete maintenance-log and spool core-weight catalog entries, completing their CRUD

Waste analytics​

• Tool-changer-aware purge accounting for multi-material prints
• Colour-aware single-nozzle purge accounting
• A smart colour-ordering recommender that finds the lowest-purge filament sequence, with a dedicated frontend panel

Slicer ⇄ fleet control​

A full remote-control API so the 3DPrintForge Slicer can drive your fleet printers directly:

• Live printer state: GET /api/printers/:id/state (read-only)
• Print control: POST /api/printers/:id/control (pause / resume / stop)
• Rich motion control: home / move / extrude / temperature / tool change
• Fan, light and speed actions for Bambu + Moonraker printers
• Filament load / unload / change for G-code printers
• GET /api/printers now exposes vendor and online/offline state
• On-demand profile push: POST /api/slicer/profiles/push

Fixes​

• Preserve the printer access code on edit (issue #12 follow-up)

Filament inventory & AMS accuracy​

• AMS 2 Pro / H2D load-cell weight is read directly instead of estimated from percent
• Recalibrate remaining weight from print history, from live AMS signals, or both combined — with new UI
• Sensor-floor guard: extrusion tracking is trusted when the load cell drops below ~20 g (it loses resolution near empty)
• used_weight_g capped at the initial spool weight; existing over-counted rows repaired (migration v142)
• Non-Bambu spools (Elegoo, Polymaker, generic) auto-detected; auto-created profiles named from the tray hex

Printers & connectivity​

• Per-printer settings now persist (#12) — LAN Developer Mode, Camera Resolution, and every other type-specific field round-trip through a new config_json column and survive a restart. Camera Resolution actually drives the stream (1080p / 720p / 480p)
• Per-brand credentials are masked in the API response and restored from storage on unchanged edits
• ffmpeg exit code 8 maps to an actionable "enable LAN Live View" hint instead of a generic camera error

Authentication & security​

• TOTP two-factor prompt wired into the login UI, with two silent-failure bugs closed
• Second-pass NIST/CVE audit fixes and hardened security headers
• Dependency security upgrades clear all open npm audit advisories
• .env-based secret handling and HTTP response compression

Performance​

• Composite database indexes remove temp-b-tree sorts from the hottest queries

3DPrintForge Slicer integration​

3DPrintForge can now drive the skynett81/OrcaSlicer fork in REST service mode instead of spawning the slicer CLI per request. The fork hosts a small embedded HTTP service (cpp-httplib); 3DPrintForge probes it, mirrors profiles automatically, and routes slicing through it when available — falling back to the CLI bridge or native engine if not.

What you get:

• Live status pill in the dashboard header
• Slice models with live progress (stage, layer counter, percent) over Server-Sent Events
• Slice-and-Send to printer in one click
• Profile catalog mirrored automatically every 5 minutes
• Cancel button mid-slice
• Multi-extruder filament breakdown
• Toast notifications on disconnect/reconnect
• Outage notifications via the existing 7-channel notifier (Telegram, Discord, email, etc.)

Surface area:

• 12 REST proxy endpoints under /api/slicer/forge/*
• Settings card auto-mounts in Slicer Studio AND System → Integrations
• Pterodactyl egg env vars (FORGE_SLICER_URL, FORGE_SLICER_TOKEN)
• Docker Compose env var examples
• Norwegian translations (27 keys) for the entire UI surface
• Setup guide and full REST contract on the docs site

For fork-side dev:

• tools/forge-slicer-mock.js — full Node implementation of the contract incl. SSE, so the integration can be tested end-to-end without waiting for a C++ build
• website/docs/forge-slicer-cpp/ — Phase-1 cpp-httplib + nlohmann/json skeleton, CMakeLists fragment, step-by-step main_integration.md
• 33 new tests covering probe + cache, multipart slice, SSE error handling, fallback chain, sync idempotency, and more

Security hardening​

A focused security audit closed six issues this release:

The audit also confirmed clean state on hardcoded secrets (none), npm audit (0 vulnerabilities), SQL injection (all parameterized), and command injection in updater.js (semver regex prevents tag-string abuse).

Filament inventory overhaul​

Major UX rewrite:

• Top-level Storage tab with location overview, drag-and-drop discoverability, first-time empty state
• Drag spools to/from Active Filament slots in every view mode (was only grid + table). Clearer swap interaction when dragging onto an occupied slot. File-drop overlay no longer hijacks internal drags.
• Bulk-add multiple spools with a prominent quantity field. "Add another" registers a second reel of the same filament without re-entering the metadata.
• Spool detail view shows storage method, last dried timestamp, and tare weight
• Stats / Storage / Database now show the full inventory, not just used spools. Stats auto-refreshes on tab switch with material reclassification. Usage Predictions surfaces both Total runway and per-material runway.
• Visual — icons added to inventory tabs for faster scanning

Analytics dashboard​

analytics-panel.js rewritten as a tabbed dashboard with auto-refresh and drill-downs across Overview, Statistics, Calendar, Filament, Cost, Waste, and Comparison views.

i18n — 504-site fix​

window.t(key, varsOrFallback) previously short-circuited on missing keys (the function returned the truthy key string, so t('foo') || 'Default' never used the fallback — users saw the raw key like 📊analytics.tab_overview). 504 sites across 28 files used that pattern. The helper now accepts a string fallback as the second argument and all call sites have been migrated.

Database — six new migrations​

• v136-138 — color hex storage normalisation (drops the leading # so '#' + color_hex no longer produces ##8c8c8c)
• v139 — comprehensive eSUN filament catalogue
• v140 — ~80 missing profiles seeded across 10 vendors
• v141 — material classification normalisation: product-line strings like "Rapid" or "PLA-Basic" roll to base materials (PLA / PETG / ABS / TPU) so Stats buckets correctly

Internal​

• CI tests — .github/workflows/test.yml runs npm test plus JSON validation for language files and the Pterodactyl egg on every push and PR to main
• Test count — 762 tests pass (up from ~720 at v1.1.20)
• Service-worker cache bumped to v196

Upgrade notes​

If you set up the 3DPrintForge Slicer integration, see the setup guide for how to launch the fork in service mode and wire it up. The integration is opt-in — leaving FORGE_SLICER_URL blank disables it and slicing continues through the existing CLI bridge or native engine.

Restart your container (or run git pull && npm install) to pick up the fixes. For Pterodactyl users, the egg env vars are visible after the next panel-side egg refresh.

Native Slicer Engine​

A complete pure-JS slicing pipeline:

• server/native-slicer.js — mesh→polygon→infill→G-code, fully integrated with mesh repair
• sliceLayer — z-plane intersection with edge-deduplication
• offsetPolygon — bbox-aware shrink (returns empty for degenerate over-shrink)
• lineInfill — adjustable density and angle
• layersToGcode + sliceMeshToGcode — produces print-ready G-code

No external slicer required, no WASM blob, no shell-out. Just JavaScript.

Slicer Studio​

A full standalone slicer program inside 3DPrintForge:

• Three.js viewport with orbit controls and per-layer preview
• Profile system — 23 default profiles seeded (12 printers, 7 filaments, 4 quality)
• Send to printer — one-click upload after slicing
• Profile editor — create, edit, duplicate, set as default

Reach it from the sidebar Library → Slicer Studio.

Slicer Bridge (Optional)​

For users who already have OrcaSlicer, BambuStudio, or Snapmaker Orca installed, the Bridge wraps their CLI for headless slicing. Auto-detects via flatpak listings and AppImage paths — no configuration required.

Scene Composer​

A 3D scene editor with BSP-tree CSG (Evan Wallace algorithm) for boolean mesh operations:

• Union, subtract, intersect on imported STL/3MF
• Mesh primitives (cube, sphere, cylinder, torus)
• Mesh transforms (translate, rotate, scale)
• Export combined scene as STL

AI Model Forge​

Text-to-3D generation with intent parsing. Type natural-language descriptions ("a 60mm phone stand", "a hexagonal storage box with lid") and the engine routes through ai-forge-generators.js to produce print-ready meshes.

Mesh Repair Toolkit​

Automatic detection and repair of broken STL/3MF files:

• Non-manifold edge fixing
• Hole filling
• Normal recalculation
• Watertight verification via lib3mf.IsManifoldAndOriented

G-code Reference & Estimator​

Built-in G-code reference (Marlin, Klipper, RepRap, Bambu) with per-command documentation, plus a time estimator that parses G-code and predicts print duration.

17 Brands, 75+ Models​

Three new protocol clients added in this release:

• Duet/RRF (server/duet-client.js) — Duet 3D control boards via REST/WebSocket
• FlashForge FNet (server/flashforge-client.js) — FlashForge proprietary protocol
• Repetier-Server (server/repetier-client.js) — multi-printer server with REST API

Combined with existing connectors:

Printer Image Service​

Real product images sourced from OrcaSlicer's GitHub repository (raw.githubusercontent.com/SoftFever/OrcaSlicer/main/resources/profiles/{Vendor}/{Model}_cover.png). Three-tier fallback:

1. Local cache (data/printer-images/)
2. OrcaSlicer GitHub URL
3. Generated SVG placeholder (per-model distinct)

Visible on the Fleet view (#fleet).

Other Improvements​
