U1Supercharged (u1sc) is unofficial custom firmware for the Snapmaker U1 3D printer.

The Snapmaker U1 is a multi-material 3D printer featuring a four-head tool-changing system designed to significantly improve speed and reduce filament waste during multi-material and multi-color printing. It utilizes SnapSwap™ technology, enabling toolhead swaps in as little as five seconds without the need for extensive filament purging, which results in up to five times faster printing and up to 80% less waste compared to conventional methods. Each of the four independent toolheads has its own extruder and nozzle, allowing for true multi-material and multi-color printing with minimal downtime.

The printer is built on a CoreXY motion platform with lightweight, rigid carbon fiber X-axis rails, supporting travel speeds of up to 500 mm/s while maintaining long-term precision across a 270 × 270 × 270 mm build volume.

This firmware enables users to unlock hidden features which are disabled by default, modify existing ones or add completely new capabilities.

At the moment the list of modifications is very short:

• Enables SSH access to the printer

In the near future we plan to publish our toolkit which will allow users to create their own custom firmware images with any features they want.

On top of that, we’ll implement:

• Improved camera quality for video streaming (1080p@30fps with hardware encoding)
• Configure Moonraker API to use the improved camera stream
  • Automatically adds the camera to Fluidd web interface and other integrations like Homeassistant
• Add Entware package manager so users can easily install additional software on their printer
• Add application storage space so that users aren’t limited by read-only root filesystem
