Mainsail is a lightweight and responsive web interface for managing 3D printers running Klipper firmware.
It provides an intuitive browser-based environment for controlling printers, monitoring jobs, editing configuration files, and managing G-code files through the Moonraker API.
This is free and open source software.
Key Features
- Responsive interface optimized for desktops, tablets, and mobile devices.
- Manage multiple 3D printers from a single interface.
- Upload, rename, delete, and organize G-code and configuration files.
- Edit G-code and configuration files with syntax highlighting.
- Review previous prints and their completion status.
- View printer usage and job success and failure statistics.
- Queue multiple print jobs and add jobs directly from a slicer.
- Create temperature presets for convenient preheating.
- Visualize the printer bed using an interactive 3D mesh graph.
- Inspect prints and follow their progress with a 3D G-code viewer.
- Monitor prints using multiple webcams.
- Automatically record print timelapses with moonraker-timelapse.
- Control relays, TP-Link devices, Tasmota devices, and other power equipment.
- Organize and manage Klipper macros.
- Customize the dashboard layout, logos, backgrounds, and CSS.
- Display additional sensors on temperature graphs.
- Use the interface in multiple languages.
