- Print from File Manager with plate selection, AMS mapping, and print options. Closes #94 - Add to queue without creating archive (reduces clutter) - Queue displays library file name, thumbnail, and print time Fixes: Queue items from File Manager now reference library files directly instead of creating archives upfront. Archives are created automatically when prints start.

"""MQTT Sniffer for Bambu Lab printers.
|
|
|
|
Connects to a printer and logs all MQTT messages to capture the exact
|
|
command format used by OrcaSlicer or Bambu Studio.
|
|
|
|
Usage:
|
|
python mqtt_sniffer.py <printer_ip> <serial_number> <access_code>
|
|
|
|
Example:
|
|
python mqtt_sniffer.py 192.168.1.100 0948BB540200427 12345678
