Snapmaker U1 – Full Klipper & WebRTC Camera Setup Guide

The Snapmaker U1 took Kickstarter by storm when it was announced as a quad-hotend 3D printer. A few months later, users received the U1 and found it to be an excellent printer, but it can be even more impressive with the Snapmaker U1 Extended Firmware.

The Snapmaker U1 Extended Firmware enables:

• Running a full & modern version of Klipper.
• Running full & modern versions of the Fluidd and Mainsail frontends.
• Fluidd/Mainsail camera support with WebRTC low-latency streaming.
• The ability to add a second USB-based webcam.
