Fluidd

Fluidd is an open-source web interface designed for the management and monitoring of 3D printers. It acts as a front-end dashboard that communicates with printers running the Klipper firmware via the Moonraker API. The application allows users to monitor print progress, adjust machine settings, and control hardware components directly from a web browser, removing the need for a physical screen on the printer hardware.

Deployment occurs on a server or a local controller, such as a Raspberry Pi, and is often installed alongside Klipper and Moonraker using the KIAUH installer. The software is also available as a Docker image, providing options for both standard and unprivileged containers to meet different security requirements. Because it is a web application, it is accessible via any modern browser on desktop, tablet, or mobile devices, enabling remote operation of the printing process.

Key features

• Responsive user interface for desktop, tablets, and mobile devices
• Customizable layouts with movable panels
• Built-in color themes
• Support for managing multiple printers from a single installation
• Official Docker image support on port 80
• Unprivileged Docker image option on port 8080
• Integration with Moonraker API for Klipper firmware control

The architecture relies on the Moonraker API to bridge the gap between the web interface and the Klipper firmware. This setup is commonly used in the Voron community and by other users of Klipper-based manufacturing setups who require a centralized point of control. The software is developed by volunteers and is tested using BrowserStack to ensure compatibility across different web environments. By utilizing a server-client model, the interface offloads the processing requirements from the printer's main controller to the host server.

Fluidd serves as a control panel for users who require a flexible, browser-based interface to operate Klipper-powered 3D printers.
