Fluidd is a lightweight & responsive web based user interface for Klipper based 3D printers. It's a web application that communicates to the Moonraker API server that drives Klipper. It's included as the web GUI as part of Elegoo's Neptune 4 distributions so it's already installed.

Point your web browser to your printer's IP address and you'll connect to Fluidd.
