Centauri Carbon Manager

A lightning-fast, zero-dependency, local Web UI replacement for the Elegoo Centauri Carbon 3D printer. Built strictly on KISS (Keep It Simple, Stupid) and DRY (Don't Repeat Yourself) principles.

Created by Broby IT.

📌 Overview

The Centauri Carbon Manager connects directly to your printer via your Local Area Network (LAN) using the SDCP (Smart Device Control Protocol) over WebSockets. It gives you instant, local access to your print files, history logs, live camera stream, and timelapse videos.

Compatibility: This application is specifically designed to work exclusively with the Elegoo Centauri Carbon (CC1) running either the Original Firmware or OpenCentauri.

Because it is built as a single, standalone HTML file with Vanilla JavaScript, there are no dependencies to install and no local servers to run.

✨ Features

• Lightning Fast: Instant WebSocket communication directly with the printer's motherboard.
• File Management: List, sort, filter, and batch-delete local GCODE files.
• Smart Print History: View past print jobs complete with print durations and thumbnail images.
• Cross-Tab Thumbnails: The manager maps history thumbnails to your local files automatically.
• Live Camera Stream: Integrated modal for viewing the printer's live MJPEG stream.
• Timelapse Downloads: Directly unlock and download MP4 timelapse videos from the printer.
• Built-in SDCP API Reference: Includes a reverse-engineered manual of the WebSocket commands.
• Multi-Language & Theming: Supports 6 languages (EN, DA, DE, FR, ES, IT) and Dark/Light mode.

🛠️ Usage

🧠 Architecture

This application is driven by a centralized State object to handle asynchronous WebSocket responses seamlessly. UI elements are rendered dynamically using DocumentFragment for maximum performance, and native browser alerts have been replaced with a custom async/await modal system.
