Changelog

All notable changes to 3DPrintForge.

v1.1.24 — Spoolman server, OBS overlay, pressure-advance pattern calibration & a big QoL/accessibility pass (2026-06-11)​

A large quality release. 3DPrintForge becomes a drop-in Spoolman server, ships an embeddable OBS/kiosk streaming overlay, adds the line-pattern pressure-advance calibration method, and lands a broad quality-of-life, undo-safety and accessibility sweep across the whole UI — plus authenticator-app 2FA for Bambu Cloud login and several real fixes for features that silently did nothing.

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 the Spoolman server, 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 view to grab the URL

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 from the pressure-advance, retraction, flow and first-layer tests to Andrew Ellis' Print Tuning Guide

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 (two of these — 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
  • One-time "What's new" feature-discovery modal and a header button to reveal the keyboard-shortcut help
  • Compact-density toggle, "continue where you left off", persisted filament inventory filters/sort, sticky table headers, auto-focus on the first field when a dialog opens, copy-to-clipboard helpers and hover-for-exact relative timestamps

UI restructure & fixes​

  • Split the overloaded Library and System menus into Prepare + Library and System + Admin
  • Cleaner dashboard idle state (no stale progress ring) and a more legible top stats strip
  • Two-up filament spool cards on phones, content-clipping fixes from a full layout scan, a clean "no preview" history placeholder, de-duplicated print-guard alerts, and a corrected queue counter (counts pending jobs, not queue containers)

Accessibility​

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

Camera​

  • Preserve aspect ratio when transcoding the RTSP stream; the REC badge shows the selected stream resolution rather than the native capture

Bambu Cloud & discovery​

  • Authenticator-app 2FA (TOTP) login support, with the real login/verify error surfaced instead of a generic message
  • Auto-fill the LAN IP for cloud-imported Bambu printers; network discovery no longer hangs

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 are recorded — the counters were never called

Maintenance​

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

v1.1.23 — Waste analytics, colour-order optimiser & slicer fleet control (2026-06-09)​

This release lands purge/waste analytics, a lowest-purge colour-ordering recommender, and a full remote-control surface for the 3DPrintForge Slicer to drive fleet printers. From this release the 3DPrintForge Slicer and Server share one product version and are released together.

Waste analytics​

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

Slicer ⇄ fleet control​

  • 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 exposes vendor and online/offline state
  • On-demand profile push: POST /api/slicer/profiles/push

Fixes​

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

v1.1.22 — Inventory weight accuracy, DB performance, TOTP login & security hardening (2026-06-06)​

A maintenance-and-accuracy release. The headline work is a top-to-bottom pass on AMS/spool weight tracking (direct load-cell readings, recalibration from snapshots + history, sensor-floor guards), a sweep of composite database indexes that removes temp-b-tree sorts from the hottest queries, TOTP two-factor at the login screen, and a security/dependency hardening pass that clears all open npm audit advisories. Also fixes GitHub issue #12 — per-printer settings that wouldn't save.

Printers & connectivity​

  • Per-printer settings now persist (#12) — LAN Developer Mode, Camera Resolution, and every other type-specific field (camera mode, cloud sync, auto-AMS sync, webcam URL, port, per-brand credentials) were sent by the edit dialog but never stored, so re-opening the dialog showed defaults. They now 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, mirroring the access-code handling
  • ffmpeg exit code 8 now maps to an actionable "enable LAN Live View" hint instead of a generic camera error
  • 3DPrintForge Slicer: status badge hidden until the integration is configured; local URL scoped correctly in the proxy handlers

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)
  • AMS slot ownership cleaned up — archiving frees the slot, and adding a spool evicts a conflicting active claim before insert (migration v147)
  • Non-Bambu spools (Elegoo, Polymaker, generic) auto-detected; auto-created profiles named from the tray hex (e.g. "PETG White")

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 4 open npm audit advisories (ws, ip-address, tmp, brace-expansion); plus server + website patch upgrades
  • .env-based secret handling and HTTP response compression

Performance​

  • Composite database indexes across activity-log, spool-event, history and bed-mesh queries eliminate USE TEMP B-TREE on the hottest paths (migrations v143–v146)
  • Frontend: all 188 component scripts deferred on initial load; StateStore notifications coalesced through requestAnimationFrame

Stability & internals​

  • 25 functional bugs fixed across three post-release code-review passes
  • 3MF converter declares its jszip dependency and hardens against malformed input
  • sendJson, the rate limiters, json-cache and http-compression extracted into focused, testable modules
  • Docs: /docs/* aliases redirect to canonical paths

Database migrations in this release: v142–v148.

v1.1.21 — 3DPrintForge Slicer integration, filament overhaul, security hardening (2026-05-03)​

Three concurrent tracks: a REST integration with our skynett81/OrcaSlicer fork, a top-to-bottom rewrite of the filament inventory experience (Storage tab, drag-and-drop, bulk-add), and a security audit that closed six CVE-class issues. Plus an i18n overhaul that fixed a broken-fallback pattern across 504 call sites, a tabbed Analytics dashboard, and 6 new database migrations.

3DPrintForge Slicer fork integration​

3DPrintForge half of an integration with the skynett81/OrcaSlicer fork. The fork hosts a small REST service (cpp-httplib) that 3DPrintForge talks to instead of spawning the slicer CLI per request. Profiles mirror automatically; slicing routes through the fork when available and falls back to the CLI bridge / native engine when not.

  • API contract (website/docs/FORGE_SLICER_API.md) — every endpoint specified, 5-phase rollout, error codes, auth model
  • Node REST client (server/forge-slicer-client.js) — probe with 60 s cache, profile listing, multipart slice, gcode download, PNG preview, optional bearer token, env overrides, SSE error event handling, listener API for transition events
  • Slicer resolver (server/slicer-resolver.js) — single entry point that picks the best backend in priority order (forge → bridge → native). All slicer call sites get the same return shape regardless
  • Profile sync (server/forge-slicer-sync.js) — pulls the fork's catalog into local slicer_profiles table every 5 min, archives vanished entries, idempotent on (kind, name)
  • 12 REST endpoints under /api/slicer/forge/*: status, configure, profiles, slice, slice/stream (SSE), slice-and-send, jobs, jobs/:id/gcode, jobs/:id/cancel, preview, sync, sync/status
  • Persistent settings — configure endpoint writes to config.json via saveConfig so URL/token/enabled survive restart. Bearer token is masked as '***' in /api/slicer/forge/status and the configure endpoint detects the masked sentinel to preserve the existing token on save
  • UI status card auto-mounted in Slicer Studio AND Settings → System → Integrations (forge-slicer-settings.js) with Save / Test connection / Open fork buttons, version + upstream + config-dir display, fallback explainer. The settings dialog search index also surfaces it for "forge", "orcaslicer", "fork", "rest", "slicer" keywords
  • Header badge (forge-slicer-badge.js) — small status pill in the global header with disconnect/reconnect transition toasts
  • Slicer Studio "Slice" button prefers Forge when available with SSE live progress (stage + percent + per-layer counter), Cancel mid- slice via AbortController, Slice & Send to printer in one click, multi-extruder filament breakdown
  • Notifications on outage — notifier.notify('forge_slicer_disconnected') / 'forge_slicer_reconnected' fire on probe-state transitions so outages reach Telegram / Discord / email / etc., not just the header pill
  • System Info exposure — /api/system/info carries a forge_slicer block with enabled, ok, version, upstream, last_check, and error. Settings → System Info shows a corresponding row
  • Mock server (tools/forge-slicer-mock.js) — full Node implementation of the contract incl. SSE for fork-side dev. Returns plausible profiles + slice payloads so 3DPrintForge integration can be tested end-to-end without waiting for a binary
  • C++ reference impl (website/docs/forge-slicer-cpp/rest_server.cpp) — Phase-1 skeleton using cpp-httplib + nlohmann/json. CMakeLists fragment + step-by-step main_integration.md for wiring into the OrcaSlicer entry point
  • Tests — 33 new tests across four files (forge-slicer-client.test.js, slicer-resolver.test.js, forge-slicer-sync.test.js, forge-slicer-routes.test.js) covering probe + cache, profile listing, multipart slice, gcode download, PNG preview, auth, disabled state, fallback chain, sync idempotency, archived profile handling, end-to-end HTTP route relay, SSE error events with code preservation, truncated SSE streams, listener firing semantics, and listPrinters()
  • Pterodactyl egg (egg-3dprintforge.json) — exposes FORGE_SLICER_URL and FORGE_SLICER_TOKEN so panel users can wire up the integration without editing config.json
  • Docker compose has commented FORGE_SLICER_URL and FORGE_SLICER_TOKEN examples next to the existing BAMBU env vars
  • Norwegian translations — forge_slicer.* block added to public/lang/nb.json (27 keys) so NB-locale users see translated status pills, settings card, and toasts
  • Docs — setup guide, REST contract, sidebar entry, intro page v1.1.21 section, architecture and API doc tables

SSE robustness​

Two silent-failure modes in the SSE parser were fixed after close reading of the contract:

  • event: error from the fork was previously ignored — promises hung forever. Now rejects with the message and code preserved
  • Stream ending without done (fork crash, network drop) hung the promise. Now rejects with "SSE stream ended without a done event"
  • Error payload shape was misaligned with the spec. Contract says { message, code }; client read parsed.error. Now reads message with error as legacy fallback for older fork builds

Security hardening — six CVE-class fixes​

A focused security audit found six issues. All fixed in this release:

  • CRITICAL — Path traversal (CWE-22) in server/milestone-service.js. getMilestoneFile() and getArchivedMilestoneFile() joined user-controlled printerId / filename onto MILESTONE_DIR with no boundary check. A view- permission user could escape the directory via .. segments to read any file the server process can read. Both functions now reject any resolved path that doesn't start with MILESTONE_DIR/. Regression test: tests/api/milestone-path-traversal.test.js (5 tests)
  • HIGH — Information disclosure (CWE-200). /api/settings/export returned config.notifications raw, leaking every configured channel secret (Discord webhook URL, Twilio creds, SMS gateway, webhook URL). New shared _maskNotificationSecrets() helper masks all 8 sensitive fields before export, also called by GET /api/notifications/config (which previously masked only 4 fields)
  • HIGH — XSS (CWE-79) in printer-file-browser.js. Printer- supplied filenames were interpolated into inline onclick= and confirm() strings. A malicious or compromised printer advertising a quote-and-script payload would run JavaScript in the dashboard user's browser. Switched to data-pf-action / data-pf-name dataset attributes and a delegated click handler — filename is passed as DOM data, never as JS source
  • HIGH — SSRF (CWE-918) in /api/spoolman/test. Endpoint fetched an arbitrary user-supplied URL with no guard. A view-permission user could probe cloud metadata at 169.254.169.254 for IAM credentials. Added _isDangerousUrl() that blocks link-local + non-HTTP schemes; RFC1918 and localhost are still allowed since self-hosted Spoolman commonly runs there
  • MEDIUM — Information disclosure (CWE-22) in server/slicer-bridge.js. User-supplied profile paths were passed directly to the slicer CLI. A print-permission user could point the slicer at /etc/passwd and have its logs echo the contents. Profile paths are now resolved and rejected unless they stay inside the slicer's profileDir
  • MEDIUM — Information disclosure in /api/slicer/forge/status. The bearer token was returned in plain text; matches no other secret in the project. Now masked to '***' plus a token_set: bool flag. The configure endpoint detects the '***' sentinel from the UI and preserves the existing token

Filament inventory overhaul​

Major UX rewrite of the filament panels:

  • Top-level Storage tab with locations + placement overview, drag-and-drop discoverability hints, first-time empty state, stat layout fix
  • Drag spools to/from Active Filament slots — all view modes now draggable, not just grid + table. Clearer swap interaction when dragging onto an occupied slot. File-drop overlay no longer hijacks internal element drags
  • Bulk-add multiple spools properly with prominent quantity field; "Add another" registers another reel of the same filament without re-entering the metadata. Inline shortcut from Location dropdown jumps to the Manage tab
  • 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; state-subscribe handlers wrapped in try/catch to surface real errors instead of swallowing them

Analytics dashboard​

public/js/components/analytics-panel.js rewritten as a tabbed dashboard with auto-refresh and drill-downs (Overview, Statistics, Calendar, Filament, Cost, Waste, Comparison).

i18n cleanup — 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). 504 sites across 28 files used that pattern and showed the raw key in production. The helper now accepts a string fallback as the second argument and all 504 call sites have been migrated.

Database — six new migrations​

  • v136-138 — schema fixes for color hex storage (drops the leading # so '#' + color_hex no longer double-prefixes), spool override hex normalisation
  • v139 — comprehensive eSUN filament catalogue
  • v140 — ~80 missing profiles seeded across 10 vendors
  • v141 — material classification normalisation: profiles like "Rapid" or "PLA-Basic" rolled to base materials (PLA / PETG / ABS / TPU) so Stats buckets correctly

Internal / developer experience​

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

v1.1.20 — Native Slicer, Scene Composer, AI Model Forge, Universal Vendor Coverage (2026-04-26)​

Largest release since v1.1.0. Adds our own slicer (both a desktop- slicer bridge and a from-scratch native engine), a Tinkercad-style 3D Scene Composer with real CSG, an AI Model Forge that turns text / image / sketch into printable meshes, a Mesh Repair Toolkit, G-code Reference & Estimator, printer-image cache with brand-aware fallback rendering, and expanded vendor coverage to 17 brands and 75+ printer models including the full Bambu H-series and three new protocol clients (Duet/RepRapFirmware, FlashForge FNet, Repetier-Server).

Slicer Studio + Slicer Bridge + native engine​

Slicer Studio — full standalone slicer program built into the dashboard. 3-column layout with profile-based settings (printer / filament / quality), 3D viewport showing the build volume + model, and one-click slice → toolpath → send pipeline.

  • New slicer_profiles SQLite table (migration v135) seeded with 23 default profiles: 7 filaments (Generic PLA/PETG/ABS/ASA/TPU + Bambu PLA Basic + Snapmaker PLA), 4 quality presets (Draft 0.30 mm, Normal 0.20 mm, Fine 0.12 mm, Strong 0.20 mm 3 walls 40 %), 12 printer profiles spanning Bambu/Snapmaker/Voron/Prusa/Creality
  • mergeProfiles({printerId, filamentId, processId}) overlays the three JSONs into a single settings object the native-slicer engine consumes directly
  • 5 new REST endpoints: GET / GET-by-id / POST / PUT / DELETE /api/slicer/native/profiles
  • Frontend builds on Three.js viewport with yellow wireframe build volume + translucent bed plate + 10 mm grid; auto-resizes camera based on the selected printer's buildVolume
  • Save-as-new-quality-preset button serialises overrides to a new process row

Slicer Bridge — headless slicing via the user's installed desktop slicer.

  • server/slicer-bridge.js probes for OrcaSlicer (Flatpak), Bambu Studio (Flatpak), and Snapmaker Orca AppImage at /opt/
  • pickSlicer(printerInfo) chooses per brand: Bambu printers → Bambu Studio (best AMS handling), Snapmaker U1 → Snapmaker Orca, all others → OrcaSlicer
  • listProfiles(slicer) reads the user's existing machine/filament/ process JSONs from the slicer's config directory so the same dropdowns appear as in the desktop app
  • sliceModel({modelBuffer, slicer, printerProfile, …}) writes to tmp dir, spawns --slice 0 --outputdir, captures stdout/stderr, reads the produced .gcode. 10-min timeout cap, cleanup on every exit path
  • 4 endpoints: /api/slicer/bridge/probe, …/profiles, …/slice, …/slice-and-send (atomic slice + upload-to-printer in one call)

Native Slicer — pure-JS slicing engine. Uses every existing module (format-converter, mesh-repair, mesh-transforms, stl-analyzer, gcode-time-estimator, printer-capabilities).

  • sliceLayer(mesh, z) — triangle-edge intersections at the cut plane, chained into closed polygon loops with EPS tolerance
  • offsetPolygon(poly, distance) — vertex-bisector inward/outward offset with degeneracy detection (signed-area sign flip + bbox-grew- instead-of-shrank guard)
  • lineInfill(poly, density, angle, lineWidth) — rotates polygon into hatch-aligned space, scans even-odd-fill scanlines, rotates segments back. Spacing = lineWidth / density
  • layersToGcode(layers, settings) — emits G1 X Y E F moves with full home/heat/prime preamble + cooldown finisher and per-layer retraction on travel transitions
  • sliceMeshToGcode(mesh, settings) orchestrator runs autoRepair + recenterToOrigin before slicing, alternates infill angle every layer
  • POST /api/slicer/native/slice with X-Layer-Count, X-Slice-Duration-Ms, X-Estimated-Time-Sec, X-Filament-G response headers

  • server/csg-bsp.js — pure-JS BSP-tree CSG engine (Evan Wallace algorithm, public domain) with unionMesh / subtractMesh / intersectMesh. Vec3 / Vertex / Plane / Polygon / Node primitives
    • meshToCsg / csgToMesh round-trip
  • runGeneratorWithOpts(key, opts) lets Shape Gallery insert any of the 17 Model Forge generators (keychain, gear, vase, gridfinity_bin, etc.) directly into a scene with editable opts
  • Frontend scene-composer.js:
    • 7-shape palette: box / sphere / cylinder / cone / torus / prism / pyramid + import STL/OBJ/3MF + Shape Gallery + pattern array (linear / radial)
    • Three.js viewport with OrbitControls, axis helper, workplane grid, click-to-select via raycaster, emissive highlight on selected
    • Properties panel: name, color picker, hole flag, position XYZ, rotation XYZ in degrees, scale XYZ, geometry params per type
    • Multi-select via Set<shapeId> with Ctrl+click toggle
    • Visual translate handles: 3 colored arrows on selected shape, drag to move with snap-to-grid (off / 0.5 / 1 / 5 / 10 mm)
    • Group / ungroup with parent-id transform inheritance
    • Mirror X/Y/Z, Align X-center / Y-center / Z-min for 2+ selected

  • 7 endpoints: GET/POST/PUT/DELETE /api/ai-forge/scenes, plus /render, /render-saved, /upload-mesh, /preview-shape, /generator-defaults/:key, /printer-beds (per-printer build volumes)

AI Model Forge — text / image / sketch → printable mesh​

Self-hosted, no external ML services or GPU required.

  • server/text-intent-parser.js — tokeniser + keyword matcher for shape names (cube/sphere/cylinder/cone/torus/prism/hex/pyramid, keychain, sign, vase, gear, plate, etc.), dimension parsing (20mm, 5cm, 20x30x10), key-value overrides (r=10 h=20 teeth=20), count words (one..ten / two cubes), size presets (tiny / small / huge), modifiers (hollow / twisted / rounded), quoted text extraction. Plural-handling so "boxes" → "box"
  • server/ai-forge.js — dispatcher that turns parsed intent into a mesh via mesh-primitives, routes images to imageToHeightmap (relief mode) or boundary-trace silhouette extrusion, parses simple SVG paths (M/L/H/V/Z) into extrusion polygons, and runs autoRepair before persisting STL/OBJ/3MF
  • server/ai-forge-generators.js — registry mapping 17 shape keywords to real Model Forge generators (keychain, sign, vase, gear, cable_label, storage_box, plant_pot, phone_stand, hook, cable_clip, spring, hinge, battery_holder, headphone_stand, gridfinity_bin, gridfinity_baseplate, thread)

  • mesh-transforms.js: decimate (vertex-cluster collapse), smooth (Laplacian with boundary anchoring), hollow (shell duplicate + reverse winding), splitComponents (BFS over face adjacency), scale, translate, recenterToOrigin, meshStats
  • format-converter.js: STL ↔ OBJ ↔ 3MF bidirectional, format auto-detection. STL native (binary read/write), OBJ plain-text with quad triangulation + relative-index support, 3MF via lib3mf
  • 6 endpoints: /api/mesh/{analyze,repair,transform,convert,split, split/component} — streaming binary upload (50 MB cap), returns binary mesh + report via X-Mesh-Report header
  • Frontend mesh-repair-suite.js: 4-tab panel (Repair / Transform / Convert / Split) with drag-drop file picker

G-code Reference & Estimator​

  • server/gcode-reference.js — curated catalog of 75+ commands across Marlin, Klipper, RepRap, and Bambu firmware families with descriptions, parameters, examples, and firmware tags. Searchable by code, description, parameter, category, and firmware family
  • server/gcode-time-estimator.js — trapezoidal motion model with axis feedrate clamps and acceleration limits. Tracks extrusion length, computes filament volume → weight → cost using configurable diameter, density, and price-per-kg. Layer count via slicer LAYER_CHANGE comments with Z-up fallback. Detects and exposes slicer-header values (estimated time, filament used)
  • 3 endpoints: GET /api/gcode/reference[?q=&category=&firmware=] · GET /api/gcode/reference/:code · POST /api/gcode/estimate (binary upload, 50 MB cap)

Vendor expansion — 17 brands, 75+ models​

Full Bambu Lab H-series — detectBambuModel(serial, infoModule) gained an infoModule parameter to refine via firmware-reported product_name. Added serial-prefix 0CE for H2D Pro. Capability overrides for H2D, H2D Pro (laser + refreshable nozzle + high-temp bed), H2C (vortek 7-color), H2S. Fixed model_name: 'X1E' mis-tag on the H2D Pro entry in bambu-printer-db.json.

Prusa 2024–2025 — MK4S, CORE One, HT90 / Pro HT90, Mini+, XL extended with multiExtruder + toolheads:5.

Creality — K1C, K1 SE, K2 Plus, K2 Plus Combo, Hi, Hi Combo, Ender-3 V3 SE/KE/Plus, CR-10 SE.

Elegoo — Centauri, Centauri Carbon (2024 enclosed CoreXY), Neptune 4 Plus.

Voron community — 0.1, Switchwire (CoreXZ kinematics), Phoenix.

RatRig — V-Core 3 / 3 Pro / 3.1 / 4 (V-Core 4 is the 2025 release), V-Minion compact.

AnkerMake — M5, M5C (2024 budget).

QIDI — X-Plus 3/4, X-Max 3/4, Q1 Pro, X-CF Pro, Plus4 with heated chamber and AI features per spec.

_resolveBrandRepo extended with branches for all new vendors; Creality K-series now route to dedicated source-code repos (K2_Plus_Source_Code, K1_Max_Source_Code, K1_Source_Code) rather than the brand wiki. _guessBrand regex re-ordered so brand- specific patterns run before broad rules (Sovol's SV06 no longer mis-attributed to Voron's v0, Tronxy's CRUX1 no longer to Bambu's x1).

Three new protocol clients​

For printers the existing Bambu MQTT / Moonraker / PrusaLink / OctoPrint / SACP / AnkerMake clients didn't reach.

duet-client.js — Duet/RepRapFirmware HTTP REST. Targets the official DWC interface used by Duet 2/3, E3D Toolchanger, Hangprinter, many high-end community builds. Session-aware (rr_connect timeout tracking), normalises RRF status codes I/P/S/A/D/R/B/F/C/M into our standard gcode_state schema, full command set + file ops.

flashforge-client.js — native FNet TCP-socket protocol on port 8899. Used by Adventurer 5M / 5M Pro / AD5X / Creator 4 / Guider 3 Plus when running stock firmware (no Klipper mod required). ASCII ~M### args\r\n framing with \r\nok\r\n response delimiter, M601 S1 login on connect, 3 s heartbeat, 5 s response timeout, auto- reconnect with backoff, partial-buffer accumulation for split TCP frames. Chunked binary file upload via M28 + raw socket writes + M29.

repetier-client.js — Repetier-Server REST API (default port 3344). Per-slug routing for multi-printer Repetier-Server installs, dedicated continueJob/stopJob/copyModel-autostart endpoints, generic gcode passthrough. apikey auto-appended to every request.

printer-manager.js _getConnectorType extended to dispatch to the new clients and a handful of new Klipper-brand aliases (anycubic / sovol / biqu / bigtreetech / twotrees / tronxy / mingda / kywoo). _canConnect per-type validation (Duet/FlashForge: IP only, Repetier/OctoPrint/PrusaLink: IP + apikey, FlashForge: no auth). Settings → Add Printer dropdown gained the three new options with per-type help blocks.

Printer image service​

  • server/printer-image-service.js — disk cache of vendor product photos under data/printer-images/{slug}.bin + {slug}.meta.json. Resolution order: cache hit → registry URL fetch (8 s timeout + content-type guard) → on-the-fly SVG renderer
  • server/printer-image-renderer.js — generates a brand-coloured chassis SVG for any printer based on its features. 7 chassis archetypes (bedslinger, corexy, corexy_idex, toolchanger, vortek, corexz, delta), 17 brand palettes, feature badges (AMS / CFS / IFS / CHM / IDEX / LSR / AI / CF / 350°C / MC), build-volume label
  • server/data/printer-image-registry.json — 75-entry model→URL map pointing at OrcaSlicer's open-source profile cover images on GitHub (raw.githubusercontent.com/SoftFever/OrcaSlicer/main/ resources/profiles/{vendor}/{Model}_cover.png). Stable, version- pinned, free to fetch
  • 5 endpoints: GET registry, GET image, POST upload (admin), DELETE, POST refresh-all
  • Fleet panel updated to fetch real images first, fall back to the brand-coloured SVG via <img onerror>

UI improvements — multi-column grid responsiveness​

  • .stats-tab-panel (used by Statistics, Maintenance, Filament, Waste, Errors, History, Telemetry, Protection — 8+ panels) switched from hardcoded repeat(3, 1fr) to repeat(auto-fit, minmax(320px, 1fr)) with grid-auto-flow: dense
  • 5 settings sub-tab containers (#printer-sub-content, #general-sub-content, #appearance-sub-content, #notif-sub- content, #system-sub-content) become auto-fit grids; toolbar / ID-wrapper / form-area children auto-promote to full row via :not(.settings-card) rule
  • Inventory Admin, Diagnostics & Tuning, Backup, Analytics, Plugins panels reorganised with Quick Actions bars + 2-column auto-fit grids and grid-auto-flow: dense so small cards backfill any cells next to full-width spanning items
  • Library section badge updated 7 → 11 → 12 → 13 over the release to track AI Forge / Scene Composer / Mesh Repair / Slicer Bridge / Slicer Studio
  • System section badge 7 → 12 after the three admin panels became reachable

UI fixes​

  • System sidebar admin panels were unclickable — admin- diagnostics / admin-inventory / admin-kb had data-panel + onclick="openPanel(...)" markup but no entries in PANEL_TITLES or PANEL_LOADERS. openPanel silently no-ops on unregistered names. Fixed: titles + loaders that inject the right container ID (vendor-diagnostics-2026 / inventory-admin-2026 / kb-viewer-2026) and call the corresponding render function exposed by each -2026.js component
  • Command Palette (Ctrl+K) was missing 25 panels — PANEL_LABELS had 43 entries while PANEL_TITLES had 67. Added entries for every recently-built feature (AI Forge / Mesh Repair / Scene Composer / G-code Studio / G-code Reference / Calibration / Pre-print / Slicer Bridge / Slicer Studio / admin-diagnostics / admin-inventory / admin-kb / Model Forge / Sign Maker / JSCAD / OctoPrint / Resources / Logs / Filament Analytics / 5 CRM modules)
  • Settings → Add Printer dropdown updated with 10 protocol types and richer model hints (Bambu now mentions H2D/H2D Pro/H2C/H2S, Moonraker mentions all 7 new Klipper brands, PrusaLink mentions MK4S/CORE One/HT90)

Internal​

  • New tests: 18 mesh-repair / mesh-transforms / format-converter, 21 printer-capabilities-2026, 6 bambu-model-detect new cases, 20 moonraker-brand-repos extended, 13 scene-builder, 10 csg-bsp, 8 slicer-bridge, 17 native-slicer, 11 printer-image-service, 7 printer-image-renderer, 26 gcode-reference / gcode-time-estimator, 10 slicer-profiles, plus AI Forge, Scene Composer groups, generator- shape, mesh-primitives, text-intent-parser suites
  • Test count: 725 → 783 since v1.1.19 (full suite passing)
  • 21 server modules previously developed but not git-tracked are now in the repo (filament-db-refresh, spoolman-*, kb-importer, prusa-connect, webhook receivers, etc.)
  • data/ directory entries for printer-images and ai-forge-output are runtime-generated — not git-tracked

Unreleased (carried forward — staged for v1.1.21+)​

The pre-existing 'Unreleased' content from the v1.1.19 cycle covering auth/PrusaLink 1.8/Moonraker JWT/Bambu ACS/spoolman v2/H2D AI toggles/etc. ships as part of v1.1.20 above — those entries described features now wired end-to-end and committed during this release cycle.

v1.1.19 → v1.1.20 — historical context kept below​

Vendor firmware compatibility — 2025–2026 rollups​

Bambu AMS 2 Pro / AMS HT / H2D​

  • New detectAmsModel() identifies AMS 2 Pro (hw_ver N3F05), AMS HT, AMS Lite, and classic AMS from the info.module[] payload. Exposed as state._ams_models[]
  • Per-AMS humidity summary now includes the new humidity_raw (actual RH%), dry_time (minutes remaining), and dry_sf_reason (safety-stop reason) fields shipped with AMS 2 Pro and AMS HT firmware
  • H2D granular AI toggles under print.xcam: clump_detector (nozzle clumping), airprint_detector, pileup_detector (purge chute), and printing_monitor master toggle — with correct MQTT field names verified against OpenBambuAPI
  • buildPrintCommand() now recognises http://, https://, file:///, and ftp(s):// URL schemes — enables H2D start-print-over-LAN without a USB stick (Bambu Forum #234923)

Moonraker Spoolman v2​

  • New _spoolmanProxy() helper opts into Moonraker's use_v2_response=true envelope, separating Spoolman-side errors from Moonraker transport errors
  • Proxy path corrected from /api/v1/spool → /v1/spool (Moonraker 0.9+ rejects paths not starting with /v1/)
  • Structured error reporting: { ok, data?, error?: { status_code, message } }

Snapmaker U1 Extended / Creality K2 / QIDI Plus4​

  • No API changes required — these printers work via the existing dynamic printer.objects.list auto-discovery
  • Chamber heater now promoted to state._chamber_heater for quick access — covers K2, QIDI Plus4/Q1 Pro, Voron Nevermore, and Snapmaker U1 cavity heaters regardless of exact heater_generic <name> spelling
  • afc and ercf already subscribed for paxx12's AFC-Lite stub; RFID via filament_detect

Slicer compatibility — 2025–2026 releases​

3MF security hardening

  • isSafeZipEntryName() rejects path-traversal (../, absolute paths, backslashes, Windows drive letters, null bytes) on every zip entry — mirrors the OrcaSlicer 2.3.2 CVE-worthy 3MF fix
  • Safer zip cursor advance so malformed/rejected entries can't break the loop

New 3MF metadata fields

  • schema_version — detected from .rels (BambuStudio 2.0+ writes a schema version; older Studio versions can only load geometry from 2.0+ 3MF files)
  • scarf_seam — from seam_slope_type=scarf (PrusaSlicer 2.9, Cura 5.9, OrcaSlicer 2.3)
  • chamber_temp — from chamber_temperature (BambuStudio H2D, QIDI Plus4/Q1 Pro up to 65°C)
  • wipe_tower_type — new OrcaSlicer 2.3+ field
  • per_extruder[] — dual-nozzle flow ratio and nozzle volume per extruder (H2D left/right)
  • RFID filament metadata per filament (rfid_uid, drying_temp, drying_time) — AMS 2 Pro auto-drying
  • exclude_objects[] — per-object id/identify_id/name from Metadata/model_settings.config for skip-during-print UI
  • bed_count + multi_bed — PrusaSlicer 2.9+ virtual beds migrated to a physical grid

Extended slicer CLI auto-detection

  • slicer-service.js now detects OrcaSlicer, BambuStudio, Elegoo Slicer, QIDI Slicer/QIDIStudio, Snapmaker Orca, Creality Print, PrusaSlicer, SuperSlicer, and CuraEngine (any usable CLI wins — all OrcaSlicer forks share the same --slice surface)
  • Profile search also covers BambuStudio, Elegoo, QIDI, Snapmaker Orca, and SuperSlicer install trees + user configs

Filament ecosystem — round 5 (final wiring + UI)​

Backend completion:

  • POST/PUT/DELETE /api/inventory/spools now fires auto-sync hooks to Spoolman fire-and-forget — local CRUD never blocks on remote
  • POST /api/extra-fields/sync pulls Spoolman's /extra_field into our schema table per entity (spool/filament/vendor)
  • GET /api/spoolman/export emits the full DB as a Spoolman-compatible { vendors, filaments, spools } JSON download
  • GET /api/inventory/spools/:id/qr.png renders a 256×256 QR code (error-correction M) encoding the spool's short_id or numeric id — backed by the qrcode npm dep we already carry
  • GET /api/inventory/spools/:id/label returns a 62×29 mm printable HTML label with QR + material + color + remaining weight + short_id — ready for print-to-PDF
  • POST /api/orcaslicer/filaments/:id/import promotes an indexed OrcaSlicer community preset into a real filament_profiles row (upserts the vendor too)
  • POST /api/filaments/find-match returns nearest SMDB/3DFP/OrcaSlicer candidates for a (vendor, material, color_hex) tuple

Frontend (inventory-admin-2026.js):

  • Collapsed "Inventory admin" panel on the dashboard with 6 sections:
    • Spoolman health badge (live WebSocket)
    • Initial-import-from-Spoolman wizard
    • Duplicate detection + merge browser
    • Cheapest-retailer-per-filament table
    • Custom-field admin (sync from Spoolman, local CRUD, delete)
    • OrcaSlicer preset browser with search + one-click import
  • Top-of-panel conflict banner appears automatically when any spool has a spoolman_sync_error
  • Export/tools row: Spoolman JSON download, manual price-track, per-vendor SMDB refresh, type-bridge refresh

Filament ecosystem — round 4 (full closure)​

New modules:

  • server/spoolman-sync-hooks.js — auto-push hooks (spool/vendor/profile) with last-writer-wins conflict detection using spoolman_updated_at timestamps
  • server/spoolman-health-monitor.js — polls Spoolman every 3 min, logs to spoolman_health_log, fires spoolman_offline / spoolman_back_online notifications via the hub + notification channels
  • server/filament-dedupe.js — fingerprint-based duplicate detection across 3DFP/SMDB/OrcaSlicer; duplicate rows link to a canonical via duplicate_of, merged source list tracked in merged_sources
  • server/spoolman-import.js — initial full-import (vendors → filaments → spools) using transactions + external_id reconciliation so re-imports update rather than duplicate
  • server/threedfp-price-tracker.js — multi-listing parser that extracts every retailer from price_data.listings[], stores time-series rows, exposes cheapest-per-profile + trend endpoints
  • server/spoolman-type-bridge.js — two-way filament_type ↔ materials_taxonomy mapping with orphan-tracking

Extensions:

  • spoolmandb-modular.js: new refreshPerVendorFilaments() fetches the per-vendor filaments/<vendor>.json files from SpoolmanDB for richer per-colour metadata
  • spoolman-client.js: added listFilamentTypes() and getStats() endpoints
  • seed-filament-db.js: now warms the filament image cache, tracks prices, and runs duplicate detection after every seed (all opt-outable)
  • Scheduler adds per-vendor refresh + type-bridge refresh to the weekly run

Migration 127 adds: spoolman_updated_at on spools, spoolman_id/updated_at/synced_at/local_updated_at/duplicate_of/merged_sources on filament_profiles, listing_id/retailer/retailer_url/in_stock on price_history, plus new spoolman_type_bridge and spoolman_health_log tables

12 new REST endpoints: POST /api/spoolman/import-all, GET /api/spoolman/health-history, POST /api/spoolman/refresh-type-bridge, POST /api/filaments/detect-duplicates, GET /api/filaments/:id/duplicates, POST /api/filaments/track-prices, GET /api/filaments/cheapest-listings, GET /api/filaments/:id/price-trend?days=, POST /api/spoolmandb/refresh-per-vendor, POST /api/filament-profiles/:id/spoolman-sync, DELETE /api/filament-profiles/:id/spoolman-sync

Conflict resolution: each two-way-sync write checks local spoolman_updated_at against the remote timestamp and sets spoolman_sync_error when a concurrent remote change is detected — UI can show "remote newer, resolve manually" without blocking local edits.

Filament ecosystem — round 3 (modular SMDB, OrcaSlicer library, image cache, extra fields)​

  • SpoolmanDB modular pull (server/spoolmandb-modular.js) — separately fetches vendors.json and materials.json so we get vendor logos/country/support-email and a real materials taxonomy (density, glass-transition temp, temp ranges, enclosure/food-safe flags) instead of flat strings. Also extracts the purge matrix when present
  • OrcaSlicer Filament Library sync (server/orcaslicer-library-sync.js) — walks SoftFever/OrcaSlicer/resources/profiles/<Vendor>/filament/ on GitHub and indexes ~1000+ community filament presets with full raw-JSON payload. Default vendor whitelist (BBL, Generic, Prusa, Polymaker, Bambu Lab, Creality, Elegoo, QIDI, Snapmaker, Voron)
  • Filament image cache (server/filament-image-cache.js) — downloads 3DFP / vendor images to <data>/filament-images/<sha256>.<ext> with a 5 MB cap and type whitelist, so the dashboard doesn't leak IPs to third-party CDNs. Auto-prunes stale entries on weekly run
  • Spoolman extra_field schema — user-definable custom fields per entity (spool/filament/vendor) with UI ordering and choice sets. Mirrors the Spoolman v2 surface
  • Vendor two-way sync hook — POST /api/vendors/:id/spoolman-sync creates or updates the vendor in Spoolman and stores spoolman_id + spoolman_synced_at locally
  • Locations → Spoolman path — locationIdToSpoolmanPath() walks our parent_id hierarchy and emits "Garage/Drybox-1/Slot-3" strings Spoolman understands. Auto-applied when POST /api/spoolman/spool receives a spool with location_id but no location
  • Purge matrix — filament_purge_matrix table seeded from SpoolmanDB, GET /api/filaments/purge-matrix?from=&to= exposes it
  • TD-vote submission — POST /api/filaments/td-vote exposes the existing submitTdVote() database helper
  • New REST endpoints: /api/extra-fields/{entity}, /api/materials/taxonomy, /api/filaments/purge-matrix, /api/orcaslicer/filaments[?vendor=&material=], /api/orcaslicer/sync, /api/spoolmandb/refresh-modular, /api/filament-image?url=, /api/filaments/td-vote, /api/vendors/:id/spoolman-sync
  • Migration 126 adds extra_field_schema, materials_taxonomy, filament_purge_matrix, filament_image_cache, orcaslicer_filaments tables + vendor metadata columns (logo_url, support_email, country_code, spoolman_id, spoolman_synced_at)

Filament inventory + locations upgrades​

  • Location climate alerts — getLocationAlerts() now also checks temp/humidity thresholds against the latest recorded reading per location. New API POST /api/inventory/locations/:id/climate lets sensors (or a cron) push readings; alert surfaces on the dashboard banner with "since" timestamp
  • Spool expiry warning — reuses the existing expiry_date column. Inventory cards now show a color-coded badge (red = expired, yellow = less than 7 days, blue = less than 30 days) via inventory-enhancements.js. API GET /api/inventory/spools/expiring?within=30
  • Direct Spoolman two-way sync — new server/spoolman-client.js with full v2 surface (vendors, filaments, spools, locations, extra_field, use). Routes: POST /api/spoolman/spool, PATCH /api/spoolman/spool/:id, DELETE /api/spoolman/spool/:id, GET /api/spoolman/health. Per-row sync state tracked via new spoolman_synced_at / spoolman_sync_error columns
  • Auto-refresh SpoolmanDB + 3DFilamentProfiles — new server/filament-db-refresh.js scheduler (weekly default). Fetches Donkie/SpoolmanDB/spoolman_json.json from GitHub, refreshes 3DFP via existing seed pipeline, records state in brand_data_refresh. Manual trigger via POST /api/spoolman/refresh-db
  • Drag-and-drop spools between locations — front-end inventory-enhancements.js binds [data-drag-spool] + [data-drop-location] attributes to a PATCH /api/spools/:id { location_id } pipe
  • Spoolman live status — notify_spoolman_status_changed + notify_active_spool_set Moonraker events broadcast on spoolman_status / spoolman_active_spool hub channels; dashboard badge (#spoolman-status-badge) updates without polling
  • Migration 125 adds expiry_warn_days, spoolman_synced_at, spoolman_sync_error on spools + last_temp, last_humidity, last_climate_at, climate_alert_since on locations

Web UI integration — all three phases (webhook routes, config fields, feature/diagnostic panels)​

Phase 1 — last mile (makes previously backend-only features usable)

  • POST /api/webhook/{octoeverywhere,obico,simplyprint} — registered with session-auth bypass (external services authenticate via shared secret / HMAC); failed verification returns 401 with a structured reason
  • Settings → Printers: new form fields for every new auth / feature flag
    • Bambu: developerMode checkbox (LAN Authorization Control System)
    • PrusaLink: password field + PrusaConnect token/fingerprint when the checkbox is enabled
    • Moonraker: JWT token field alongside existing API-key
  • Settings → Notifications: new "Incoming webhook integrations" section with shared-secret inputs + example URLs for all three services; secrets masked in getSafeConfig()

Phase 2 — visible vendor-features panel

  • New public/js/components/vendor-features-2026.js + <div id="vendor-features-2026"> container on the dashboard
  • Renders conditionally based on state/hub events:
    • Printer-model descriptor (H2D / H2S / H2C Vortek / P2S / classic)
    • AMS 2 Pro / AMS HT drying table with humidityRaw, dryTime, drySfReason
    • H2D granular AI-toggles (clump / airprint / pileup / spaghetti / first-layer / printing-monitor) with live switches
    • Chamber-heater readout + target input (0–65 °C) for X1E/H2D/H2S/H2C
    • Generic fans table (Nevermore / chamber / Squirrel — anything fan_generic * or temperature_fan *)
    • Exclude-objects skip-during-print buttons + reset-all
    • Moonraker live feed (last announcement / queue change / history entry / filelist change / service transitions)
    • Power devices (smart plug / PSU) with toggle buttons — listens for notify_power_changed
  • New commands: chamber_temp, xcam_control, exclude_object, power_toggle wired end-to-end (frontend → WS → _buildCommand → printer client → protocol)
  • buildXcamControlCommand(field, enable) + extended buildCommandFromClientMessage for Bambu; extended buildMoonrakerCommand for 11 new Moonraker actions

Phase 3 — admin diagnostics panel

  • New public/js/components/vendor-diagnostics-2026.js + collapsed <details> on the dashboard
  • One-click buttons for CAN-bus node scan, input-shaper tuning (MEASURE_AXES_NOISE, SHAPER_CALIBRATE X/Y, TEST_RESONANCES X/Y), update refresh, full update, history delete, history reset-totals, notifier test, TigerTag NFC lookup
  • CAN-bus scan results arrive via the new moonraker_canbus_scan hub channel and render inline with structured error codes
  • New REST endpoints: GET /api/tigertag/lookup?uid=, GET /api/presets/printer[?vendor=&model=], GET /api/presets/multi-material[?id=]

Additional webhook receivers​

  • Obico (server/obico-webhook.js) — HMAC-SHA256 signature via X-Obico-Signature header, raw body verified, 9 event types mapped. Covers both self-hosted Obico and moonraker-obico.
  • SimplyPrint (server/simplyprint-webhook.js) — HMAC-SHA256 over timestamp.body (GitHub/Stripe pattern), 5-minute replay window via X-SimplyPrint-Timestamp, 11 event types mapped.
  • All three webhook modules return the same normalised { type, printerId, printerName, printId, fileName, progress, snapshotUrl, error, ... } shape for downstream routing.

TigerTag filament DB lookup​

  • New server/tigertag-lookup.js — resolves TigerTag NFC UIDs to filament profiles via a bundled offline DB + optional online API fallback
  • UID normalisation handles case + separators (de:ad:be:ef → DEADBEEF)
  • In-memory cache for the process lifetime; negative lookups cached too
  • mergeOfflineDb() lets users import tags at runtime

Printer model presets (2025–2026 line-up)​

  • New server/data/printer-model-presets.json + server/printer-presets.js lookup module
  • Seeded with: Bambu H2D/H2D Pro/H2S/H2C Vortek/P2S, Prusa CORE One/One+/One L/MK4S, Creality K2 Plus/K2 Pro, Elegoo Centauri Carbon / CC2, QIDI Plus4/Q1 Pro/Q2/Q2C, Snapmaker U1
  • Each preset: build volume, nozzle count, dual-nozzle flag, chamber-heating flag + target, capability tags
  • Placeholder entries for announced-but-unshipped hardware (Prusa INDX, Elegoo CANVAS) so the UI can render a "capability recognised, support pending" banner

Multi-material system catalogue​

  • New server/multi-material-capabilities.js — canonical descriptor for every MM/toolchanger we recognise (AMS variants, MMU3, ERCF, AFC-Lite, Vortek, QIDI Box, CFS, Snapmaker U1 toolchanger) + INDX and CANVAS placeholders
  • isPlaceholderSystem(id) surfaces hardware that's announced but not yet accessible

Filament types 2025–2026​

  • New server/data/filament-types-2026.json seeds PETG HF, TPU HF, Prusament PC Blend Tungsten, Polymaker Satin, and 15 Snapmaker RFID colors released March 2026
  • Tungsten Carbide nozzle metadata (H2D Pro / abrasive filaments)

OctoPrint 1.11+ plugin hooks​

  • getHealthChecks() — passthrough to the new /api/plugin/health_check endpoint added in OctoPrint 1.11.0
  • getMfaStatus() — detect and render 2FA enrollment for the new MfaPlugin type
  • New passthroughs for popular plugins: Octolapse, PrintTimeGenius, HeaterTimeout, Firmware Updater — all return null (not error) when the plugin isn't installed

OctoEverywhere webhook receiver​

  • New server/octoeverywhere-webhook.js — verifyOctoEverywhereWebhook(body, expectedSecret) validates an OctoEverywhere print-event webhook and normalises it for downstream routing to any of our 7 notification channels
  • Constant-time SecretKey comparison against the user-configured value (OctoEverywhere does not sign payloads with HMAC — secret is embedded in JSON)
  • Full EventType → name map (1–16): print_started, print_complete, print_failed, print_paused, print_resumed, print_progress, gadget_possible_failure, gadget_paused_print, error, first_layer_complete, filament_change_required, user_interaction_required, non_supporter_notification_limit, third_layer_complete, bed_cooldown_complete, test_notification
  • Handles string / Buffer / pre-parsed bodies; returns structured { ok, reason, status } for 400/401/500 cases
  • Accepts minimal payloads gracefully — missing optional fields normalise to null

Moonraker update_manager + service_start + input shaper​

  • refreshUpdateStatus(name?) (POST /machine/update/refresh) — rescans upstream repos without installing
  • triggerFullUpdate() (POST /machine/update/full) — runs klipper + moonraker + system + web-client updates in one go
  • New service_start action mirrors existing service_restart / service_stop — full systemd lifecycle from the dashboard
  • measureAxesNoise(), shaperCalibrate(axis?), testResonances(axis, output?) — Klipper input-shaper tuning commands with axis validation (only [XYZE] accepted) to prevent gcode injection via the axis parameter

ha-bambulab entity parity + chamber control​

  • AMS tray parsing now surfaces the full ha-bambulab-equivalent attribute set per slot: tagUid, trayUuid, trayInfoIdx, multi-color colors[] palette, bedTempType, flow ratio flowRatio (from n), caliIdx
  • New buildChamberTempCommand(targetC) in mqtt-commands.js — sets chamber heater target on X1E/H2D/H2S/H2C; clamps to 0–65 °C vendor-safe range and rounds to integer

Moonraker history CRUD + notifier test​

  • getHistoryJob(uid), deleteHistoryJob(uid), resetHistoryTotals() fill out the /server/history/* surface beyond list + totals
  • testNotifier(name) triggers a test notification through any configured Moonraker [notifier] (Apprise passthrough) — useful for "Test" buttons in the dashboard

Generic fan discovery​

  • Auto-discover fan_generic * and temperature_fan * Klipper objects (Nevermore carbon filter, Squirrel exhaust, named cooling fans) and expose under state._generic_fans — each entry has kind, speed, rpm, temperature, target
  • Mirrors the dashboard pattern we already use for _generic_heaters

Moonraker power control + object skip​

  • notify_power_changed handler — live updates from [power] component (smart plugs, GPIO, HomeAssistant switches) broadcast on moonraker_power channel
  • togglePowerDevice(device) — reads current state and issues the opposite action; returns the new state
  • Removed duplicate getPowerDevices() / getPowerDeviceStatus() methods; canonical versions kept (the one returning the device status string, not the wrapping object)
  • Klipper EXCLUDE_OBJECT surface — new excludeObject(name), excludeObjectById(id), and resetExcludedObjects() methods so the dashboard can drive skip-during-print on any Klipper printer with [exclude_object] (default in OrcaSlicer-configured installs)

Moonraker CAN-bus node discovery (setup UI)​

  • New scanCanbus(interface?) method returns a structured { ok, uuids, error, interface } result — distinguishes successful scans (with empty UUIDs) from arbitration errors, unknown interfaces, and unreachable Moonraker
  • Error codes: arbitration_error (broken termination / single-node bus / no-ACK), interface_not_found (no such can0/can1), unreachable (network/auth/timeout), http_error (other non-2xx)
  • The legacy getCanbusUuids() thin wrapper remains for back-compat
  • Use case: setup-UI flow for Klipper + Katapult users to find unassigned CAN nodes during initial provisioning

Prusa Connect cloud camera relay​

  • New server/prusa-connect.js — PrusaConnectClient that pushes JPEG snapshots to Prusa Connect so users can see their prints in the official Prusa mobile app
  • PUT /c/snapshot with Token + Fingerprint headers (per Prusa Connect OpenAPI spec); 16 MB size cap enforced client-side
  • PUT /c/info for camera config/options/capabilities metadata
  • Opt-in: users add prusaConnect: { token, fingerprint } to the printer config — no effect if the block is missing
  • Silent-on-HTTP-error: relay loops keep running even if Prusa Connect is unreachable or returns 5xx

Ecosystem & model coverage​

Bambu 2026 model line-up

  • detectBambuModel(serial) maps serial-number prefixes (00M, 03W, 01P, 01S, 039, 030, 094, 0CM, 0CS, 0CC) to a model descriptor with id, label, nozzleCount, dualNozzle, and amsDefault
  • Covers H2D (dual-nozzle), H2S (single-nozzle 2× X1C volume), and H2C Vortek (7-nozzle, FormNext 2025) alongside classic X1C/X1E/P1P/P1S/A1/A1mini/P2S
  • state._printer_model populated at constructor time — UI can pick the right variant before the first MQTT payload
  • Explicit MQTT clientId: 3dprintforge-<serial> — stable across reconnects, avoids library-random IDs and Bambu's flagged nodered_* prefix for per-account connection-cap diagnostics

Moonraker real-time notifications

  • _handleWsMessage now handles five additional Moonraker 0.8+ JSON-RPC notifications:
    • notify_announcement_update / notify_announcement_dismissed → moonraker_announcement channel
    • notify_job_queue_changed → moonraker_queue (live queue state without polling)
    • notify_history_changed → moonraker_history
    • notify_filelist_changed → moonraker_filelist
    • notify_service_state_changed → moonraker_service (systemd Klipper up/down)
  • Unknown notification methods are silently ignored — defensive for forward-compat

AnkerMake marked legacy

  • Anker exited the FDM market in 2025 (M5, M5C, M5X discontinued; no more parts or firmware updates)
  • AnkerMakeClient.connect() now logs a LEGACY warning; file header documents the vendor exit
  • Integration kept for users running existing hardware via ankerctl, but new deployments should pick a different printer

Verified no-op items (no code change required)​

  • Prusa Core One L bed-LED progress indicator (firmware 6.5.3+) — drives the physical LED from the printer's own progress value, not exposed as a separate API field. Our existing mc_percent surface already stays in sync with the LED
  • Moonraker enable_inotify_warnings → enable_observer_warnings rename — this is a moonraker.conf server-side config key owned by the user, not read or written by our client

Bambu Authorization Control System (2025)​

  • Detects and classifies MQTT auth failures (CONNACK 4/5, "Not authorized", "Bad user name or password") and broadcasts a banner to the dashboard with hints on enabling LAN-only Developer Mode
  • New developerMode: true flag in printer config silences the startup warning once Developer Mode has been enabled on the printer
  • Deduplicated auth-error broadcasts (once per session, not per retry)
  • Switched to HTTP Digest Auth with cached realm/nonce — no more per-request 401 probe roundtrip once the challenge is known
  • Username/password preferred when configured; falls back to API-key only for legacy firmware < 1.8
  • Broadcasts auth_error with credential-hint after persistent 401

Moonraker / Klipper (0.8+ auth tightening)​

  • New _authHeaders() helper prefers Authorization: Bearer <token> over X-Api-Key (both supported; JWT-first aligns with newer Moonraker releases)
  • WebSocket auth now uses one-shot token via /access/oneshot_token — query-param token avoids the unreliable header-based upgrade auth path
  • Sends server.connection.identify RPC (replaces deprecated server.websocket.id) with client_name: 3DPrintForge, version, and access credentials for proper session tracking

Internal​

  • New test suite: tests/clients/{bambu,prusalink,moonraker}-auth.test.js — 20 tests, 0 regressions on the remaining 178 tests
  • getSafeConfig() now masks the new token and password printer fields
