- Show firmware version badge on printer card (green=up to date,
orange=update available) with click to view release notes or
start update workflow
- Badge only shown when firmware checking is enabled in settings

The remote_interface_ip setting only worked in proxy mode but was
completely ignored in server modes (immediate/review/print_queue).
Users with multiple NICs (LAN + Tailscale, Docker bridges) got wrong
auto-detected IP in SSDP broadcasts and TLS certificates.
Users can now choose their preferred slicer (Bambu Studio or OrcaSlicer)
in Settings → General. All "Open in Slicer" buttons across Archives,
3D Preview, and context menus use the correct protocol for the selected
slicer. OrcaSlicer uses orcaslicer://open?file=<URL> on all platforms;
Bambu Studio uses bambustudio:// (Windows) or bambustudioopen:// (macOS/
Linux). Default remains Bambu Studio for backward compatibility.
Users who use OrcaSlicer without Bambu Cloud can now import slicer
presets directly into Bambuddy. Supports .orca_filament, .bbscfg,
.bbsflmt, .zip, and .json exports with automatic inheritance resolution
via OrcaSlicer's GitHub base profiles (cached with 7-day TTL).
The Add Printer dialog previously required users to manually enter their
network subnet for scanning (defaulting to 192.168.1.0/24). Now the
backend detects available network interfaces and returns their subnets
via the /discovery/info endpoint. The frontend auto-selects the first
detected subnet and shows a dropdown when multiple subnets are available,
falling back to a text input if none are detected.
AMS Lite units (A1 series) have no weight sensor and always report 0%
fill level. When a spool is linked to Spoolman with weight data, use
Spoolman's remaining weight as a fallback. External spools also show
fill level from Spoolman data instead of always showing unknown.
Backend: Enrich GET /spoolman/spools/linked response with
remaining_weight and filament_weight alongside spool ID.
Frontend: Add getSpoolmanFillLevel() helper. Update regular AMS, HT
AMS, and external spool fill computations to use Spoolman fallback
when AMS reports 0%. Show "(Spoolman)" indicator in hover card when
fill data comes from Spoolman.
Introduces a new "Proxy Mode" for the Virtual Printer that enables
remote printing from anywhere in the world without VPN, port forwarding,
or Bambu Cloud dependency.
Bambuddy acts as a TLS relay between a remote slicer (Bambu Studio/
OrcaSlicer) and the local Bambu Lab printer:
Remote Slicer → Internet → Bambuddy Server → Local Network → Printer
The slicer connects to Bambuddy using the real printer's serial number
and access code. Bambuddy authenticates and relays all FTP (file transfer)
and MQTT (commands/status) traffic with end-to-end TLS encryption.
- No port forwarding required - printer stays safely on local network
- No VPN needed - connect from coffee shops, hotels, work, anywhere
- No Bambu Cloud dependency - fully self-hosted solution
- End-to-end TLS encryption on FTP (port 9990) and MQTT (port 8883)
- Works with Bambu Studio and OrcaSlicer
- Uses real printer credentials for authentication
- Automatic printer selection from connected printers
- Add SlicerProxyManager class for TLS relay (tcp_proxy.py)
