Fixed

  • CC2 speed mode no longer flips, and the pin no longer misfires on
    firmware 02.01.00.00.     The newer firmware streams
    gcode_move.speed_mode in its real-time (method 6000) pushes as the
    current gcode move's speed factor, which oscillates 1↔2 as the head
    runs different features — it is no longer the stable "set" mode the
    older firmware exposed. This caused two problems: the UI flipped
    ~1×/sec, and the old wire-observation pin logic mistook a long
    balanced-speed feature stretch for a human choosing balanced and
    spuriously released the pin (and could re-learn/re-apply the wrong
    mode). The speed pin is now explicit only: set via
    set_print_speed, re-applied once when a Canvas filament switch
    completes (the point the firmware historically reset it — harmless if
    already correct), and cleared when the print ends. pycentauri never
    infers or sends a speed command from wire observation. The displayed
    mode reflects the pin (or a debounced wire value when unpinned), so it
    stays stable. Backward compatible: the switch-completion re-apply
    covers the older firmware's post-switch reset without depending on the
    wire value.
  • CC2 web UI now shows the current layer. The CC2's status payload
    has no total-layer field (only current_layer), so the UI — which
    required both — showed nothing. CC2Printer now looks up the printing
    file's layer count from its metadata (method 1044) once per file and
    caches it, so the UI shows "layer N / total". The layer also renders
    with just the current number when the total isn't yet known.
  • Webcam no longer stalls after a second / on refresh. The printer's
    MJPEG camera server has very few connection slots and releases them
    badly (closed connections linger in FIN-WAIT-2, still holding a
    slot). The old /stream opened a fresh upstream connection per request
    — every tab, and every client-side reload — which exhausted the slots
    and starved the stream (observed live 2026-07-08 on CC1: a sole fresh
    client got zero frames). /stream now shares a single upstream
    connection across all browsers via a CameraBroadcaster, so the
    printer only ever sees one camera connection regardless of tabs,
    refreshes, or reloads. Verified live: 4 concurrent clients → 1 printer
    connection, ~10 fps sustained, no connection pileup.
  • The camera broadcaster detects a stale upstream (TCP alive but no
    frames for 15 s) and reconnects automatically, instead of silently
    hanging forever (observed 2026-07-09 on CC1).

Added

  • File management (CC2, firmware 02.01.00.00+). Four new MQTT methods
    reverse-engineered from Orca's live wire traffic (2026-07-10):
    • list_files(storage, offset=, limit=) — method 1044, params
      {"storage_media": "local"|"u-disk", "offset", "limit"}. Returns
      file_list with filename, size, create_time, layers, print_time,
      color_map, total_filament_used. Surfaced as centauri files,
      GET /files, and MCP list_files.
    • delete_files(filenames, storage=) — method 1047, params
      {"storage_media", "file_path": [...]} (batch delete, array of
      names). Surfaced as centauri delete, POST /files/delete, and
      MCP delete_files. Requires enable_control.
    • disk_info() — method 1048. Returns total_bytes, used_bytes.
      Surfaced as centauri disk, GET /disk, and MCP disk_info.
    • print_history() — method 1036. Returns history_task_list.
      Surfaced as centauri history, GET /history, and MCP
      print_history.
      All four are CC2-only; CC1 raises PrinterError (SDCP Cmd 258 for
      file listing is disabled in the firmware). Full upload-list-delete
      cycle verified live on CC2.
  • Chamber light on/off (both models). set_light(on) — surfaced as
    centauri light on|off, POST /light, MCP set_light, and a Light
    toggle in the web UI. Requires enable_control. CC2 uses MQTT method
    1029 {"power": 0|1} (captured from Orca's wire traffic); CC1 uses
    SDCP Cmd 403 {"LightStatus": {"SecondLight": 0|1}} (verified live
    on V0.3.0-o). Both field names were commented out in Elegoo's SDK.
  • File upload across every surface. upload_file() pushes a local
    file to the printer's internal storage over chunked HTTP (port 80),
    independent of the control channel. CC1 uses multipart
    POST /uploadFile/upload; CC2 uses PUT /upload with Content-Range
    • X-Token. Surfaced as centauri upload (with --start),
      POST /files/upload (multipart), MCP upload_file, and a web UI
      upload control. Requires enable_control. Verified live on CC2.
