- Replace TagDetectedModal with inline SpoolInfoCard/UnknownTagCard
in dashboard right panel (known spools show assign/sync/close,
unknown tags show add-to-inventory/link/close)
- Rewrite AssignToAmsModal as full-screen overlay reusing AmsUnitCard,
with AMS-HT and external slot support, single assignSpool API call
- Remove printer selector from assign modal (uses top bar selection)
- Extract filament_id <-> setting_id conversion to shared utility
(backend/app/utils/filament_ids.py), used by inventory + cloud routes
- Normalize slicer_filament in assign_spool to derive proper
tray_info_idx and setting_id for MQTT (was sending setting_id="")
- Rename SpoolBuddy top bar status label "Online" -> "Backend"
- Remove weightStable guard from sync weight button
Frontend: Replace inline SpoolInfoCard/UnknownTagCard with full-screen
TagDetectedModal that auto-opens on NFC tag detection. Known spools show
remaining weight, fill bar, and offer "Assign to AMS" (new sub-modal with
printer selector + AMS slot grid) and "Sync Weight". Unknown tags offer
"Add to Inventory" and "Link to Spool". Modal stays open on tag removal,
won't re-open for dismissed tags, reopens on re-place after removal.
Daemon: Fix PN5180 NFC reader silently stopping tag detection when the
reader drifts into a stuck state. Add auto-recovery (full hardware reset
after 10 consecutive errors), preventive RF cycling every 60s when idle,
and periodic status logging. Heartbeat now reports actual nfc_ok/scale_ok
from reader instances instead of hardcoded True.
Enlarge all interactive elements across 9 SpoolBuddy components to meet
44px minimum tap targets on the RPi touchscreen. Increase nav icons
(20→24px), labels (10→12px), bar heights, section headers, printer
buttons, spool visualizations, fill bars, and status indicators.
Compact the dashboard stats bar and remove the printers card. Add
fullScreen prop to ConfigureAmsSlotModal with two-column layout
(filament list left, K-profile + color right) to eliminate scrolling.
SpoolBuddy turns a Raspberry Pi 4B with a PN5180 NFC reader and
NAU7802 scale into a filament management station that integrates
with Bambuddy via REST API and WebSocket.
Backend: SpoolBuddyDevice model, 10 REST endpoints (/spoolbuddy/*),
6 WebSocket broadcast types, background offline-detection watchdog.
RPi daemon: asyncio service with concurrent NFC polling (300ms,
MIFARE Classic + Bambu HKDF key derivation), scale reading (10 SPS,
5-sample moving average, stability detection), and 10s heartbeat
with exponential backoff reconnect.
Frontend: kiosk-optimized 1024x600 UI at /spoolbuddy with Dashboard
(live weight + NFC spool detection), AMS Overview, Inventory,
Printers, and Settings pages. useSpoolBuddyState reducer hook
driven by WebSocket CustomEvents.
i18n: all 6 locales (en, de, fr, it, ja, pt-BR).
