Reproduced live during the #1133 rollout: the SpoolBuddy display kept
serving the pre-fix picker for hours after every cache-clear,
chromium-restart, and pkill attempt because a chain of stale state
across HTTP cache + Service Worker + persistent profile prevented
fresh code from reaching the running tab.
Three independent changes — any one of them sufficient on a clean
profile, but all three needed to escape an already-corrupted one:
(1) backend/app/main.py — index.html now served with
Cache-Control: no-cache, must-revalidate on both / and the SPA
catch-all. Vite emits content-hashed JS/CSS bundle filenames so the
assets themselves are safe to cache forever, but the HTML wrapping
them is the only file that knows which hash is current. Without
explicit cache directives Chromium falls back to heuristic caching
(typically 10% of time since Last-Modified) and on long-running
kiosks happily serves stale HTML across browser restarts. That stale
HTML references an old bundle hash which is also still in disk
cache, so the kiosk runs pre-deploy JS forever without ever knowing
why.
(2) frontend/public/sw.js — CACHE_NAME bumped from bambuddy-v25 to
bambuddy-v26 so any client that fetches the new sw.js drops its old
CacheStorage. The SW does network-first for HTML/JS/CSS but
intercepts and falls back to cache, and cache-control on HTTP
responses doesn't reach into the SW's own cache layer.
(3) spoolbuddy/install/install.sh — generated kiosk launcher now uses
--user-data-dir=/tmp/spoolbuddy-kiosk-userdata with a pre-launch
rm -rf, so every kiosk restart starts from a clean slate (no HTTP
cache, no SW registration, no IndexedDB). Trade-off is a slightly
slower first paint and zero offline support; neither matters for a
single-purpose kiosk facing a backend on the same LAN, and the
guarantee that next-deploy-just-works is worth far more.
4 new tests in test_static_html_cache_headers.py: index.html on /
and SPA catch-all paths emit Cache-Control: no-cache,
must-revalidate; API routes are unaffected (no leak of HTML cache
directive onto endpoints we want React Query to cache aggressively).
For existing kiosks already trapped by an old persistent profile,
operator runs once: rm -rf ~/.config/chromium && systemctl restart
getty@tty1.service. The new launcher then picks up automatically.
The Bambu Lab X2D (launched April 2026, dual-nozzle, enclosed, hardened
steel rod gantry, AMS 2 Pro compatible) identifies itself as internal
model code N6 via SSDP/MQTT, and real serials begin with 20P9. None of
these identifiers existed in Bambuddy's registries, so the camera
service fell back to the chamber-image protocol on port 6000 (X2D
doesn't speak it), firmware-check logged "Unknown printer model: N6",
and the dual-nozzle K-profile paths — gated on the H2D serial prefix
"094" — would have treated X2D as single-nozzle.
Backend:
- Register N6 → X2D across every registry (PRINTER_MODEL_ID_MAP,
PRINTER_MODEL_MAP, STEEL_ROD_MODELS, ETHERNET_MODELS,
CHAMBER_TEMP_SUPPORTED_MODELS, firmware-check API keys + wiki path,
virtual-printer SSDP/product/serial tables, DB vp_model_fixes).
- supports_rtsp(): match the X2 display-name prefix and the N6 internal
code; camera now routes to RTSP on port 322.
- Dual-nozzle serial prefix check in bambu_mqtt.delete_kprofile and
kprofiles.set_kprofile broadened to ("094", "20P9") — X2D now takes
the H2D-style cali_idx in-place edit path.
- is_h2d model gate in bambu_mqtt.start_print extended with "X2D" so
timelapse / bed_leveling / flow_cali / vibration_cali / layer_inspect
are sent as integers and external-spool ams_id 254/255 routing is
preserved (H2D-style deputy-nozzle addressing).
X2D uses hardened steel rods like P2S — it is intentionally placed in
STEEL_ROD_MODELS, not CARBON_ROD_MODELS. A regression-guard test pins
the classification.
Frontend:
- mapModelCode in PrintersPage and SpoolBuddyAmsPage handle N6 and X2D.
- Enclosure-door badge and airduct-mode whitelists include X2D.
- MaintenancePage.getMaintenanceWikiUrl routes X2D to P2S wiki URLs for
steel-rod lubrication, belt tension, cold-pull, and PTFE tube
(exported to enable direct unit testing).
Tests:
- test_printer_models.py: TestX2DModel (10 assertions).
- test_bambu_mqtt.py: X2D in start_print ams_mapping and is_h2d gate;
TestDeleteKProfileDualNozzleDetection across H2D, X2D, P2S, X1C.
- MaintenancePageWikiUrls.test.tsx: 15 assertions covering X2D, P2S
regression, X1C/H2D/A1Mini regression, and model-name normalisation.
Docs:
- README: added X2 series to the supported printers table.
- CHANGELOG: new entry under 0.2.3b4 Fixed.
Credit to @krautech for the report and debug bundle, and to @legend813
for PR #989 which seeded most of the registry changes — rod-type
classification was corrected (steel, not carbon) and the dual-nozzle /
K-profile / is_h2d gaps were added on top.
The strict CSP added in 0.2.3b4 blocked three things at once:
external sidebar-link iframes (no frame-src declared, so they fell
back to default-src 'self'), the inline service-worker registration
script in index.html, and the Google Fonts @import used for Inter.
- Add `frame-src 'self' https:` so user-configured HTTPS iframe
targets load; frame-ancestors 'none' still prevents Bambuddy
itself from being framed cross-origin.
- Move the inline SW-registration script into public/sw-register.js
so `script-src 'self'` covers it without 'unsafe-inline' or
per-build hashes.
- Allow fonts.googleapis.com in style-src and fonts.gstatic.com in
font-src so the Inter webfont loads.
The SW used stale-while-revalidate for JS/CSS, serving old cached
bundles even after a new build. Changed to network-first (Vite already
content-hashes filenames), bumped cache version v24→v25, and added
Cache-Control: no-cache to the sw.js endpoint so browsers always fetch
the latest service worker.
When printing from the file manager, the print modal showed all printers
including busy ones. Selecting a busy printer resulted in a failed send.
The printer selector now fetches live status for each printer and shows
state badges (Idle, Printing, Paused, etc.). In reprint mode, non-available
printers (anything other than IDLE, FINISH, FAILED) are grayed out and
not selectable. "Select all" skips them. Queue/edit modes still allow
selecting busy printers since the job will wait.
Resize PWA icons to match their declared dimensions (192x192, 512x512,
180x180), split discouraged "any maskable" icon purpose, and add mobile
and desktop screenshots to manifest.json for Chrome's richer install UI.
1. H2C printer card was showing the H2D image — added dedicated
h2c.png and updated getPrinterImage() mapping.
2. Nozzle rack hover card showed raw filament IDs (e.g. "GFU99")
instead of human-readable names. Now resolves names via 3-tier
fallback: Bambu Cloud → local slicer profiles → raw ID.
- Frontend: nozzle rack filament_id values included in cloud
lookup query; NozzleSlotHoverCard displays resolved name.
- Backend: get_filament_info endpoint refactored from cloud-only
to cache → cloud → local profiles. Matches local presets by
setting_id in the imported OrcaSlicer JSON blob.
Camera streams on macOS Safari were failing with "FetchEvent.respondWith
received an error: Load failed" because the Service Worker was intercepting
MJPEG streaming responses. Safari has known issues handling continuous
streaming responses through Service Workers.
- Add exclusion for /camera/stream and /camera/snapshot URLs in SW fetch handler
- Bump cache version to v24 to force SW update on clients
The camera components already have robust error handling with reconnect logic,
so bypassing the SW for these endpoints is safe and improves performance.
