Klipper Firmware & Slicer Setup
Web interface
Open the printer's IP address in a browser to reach Fluidd or Mainsail. From there you can upload G-code, watch temperatures, edit the config and see the console.
Firmware updates
Elegoo publishes firmware images on its website. Follow their instructions exactly and back up your printer.cfg first — a wrong file can stop the printer from booting.
Slicers
Elegoo Cura and OrcaSlicer both have Neptune 4 Pro profiles. OrcaSlicer can upload directly to the printer through the web interface.
