    Leveling and Loading Filament

    The Elegoo Neptune 2S printer requires manual leveling. Here is how you can do it:

    1. Start by turning on the printer and letting it heat up.
    2. Use the included leveling knobs to adjust the height of the printing bed. This ensures that the nozzle is at the correct distance from the bed.
    3. Place a piece of paper on the bed and move the nozzle down until it lightly touches the paper.
    4. Adjust each leveling knob until there is a slight resistance when sliding the paper under the nozzle.
    5. Repeat this process for all four corners of the bed to ensure it is level.
    6. Once leveled, you can load filament into the printer’s extruder.
    7. Open the extruder door and insert your filament into the feeding tube until you feel resistance.
    8. Follow your printer’s instructions to feed and load filament through the extruder.

    Preparing Files and Software

    To start printing with the Elegoo Neptune 2S, you need to prepare your files and software. Here’s how:

    1. Download the slicing software: Use a slicer program like Cura or PrusaSlicer to prepare your 3D models for printing. These programs allow you to adjust settings like print speed, layer height, and infill density.
    2. Import your model: Open the slicing software and import the 3D model file you want to print. Most slicers support popular file formats like .STL or .OBJ.
    3. Adjust settings: Configure the printer settings in the slicer software according to your preferences and requirements. This includes choosing the appropriate print quality, infill density, and support structures if needed.
    4. Generate G-code: After adjusting the settings, generate G-code by clicking on the “Slice” or “Export” button in the slicer software. The G-code is a set of instructions that tells the printer how to move, extrude filament, and build each layer of your model.
    5. Transfer files to SD card: Save the generated G-code file onto an SD card provided with the Elegoo Neptune 2S. Insert it into the printer’s SD card slot for easy access during printing.
    6. Load filament: Make sure there is enough filament loaded into the printer’s extruder before starting a print job. Follow the instructions in the user manual on how to properly load filament into the printer.
    7. Leveling bed: Before printing, ensure that the bed is leveled properly for optimal adhesion and print quality. Use either manual leveling or follow any automated bed leveling procedures outlined in the user manual.
    8. Start printing: With everything prepared, select your desired 3D model from the printer’s menu interface, adjust any additional settings if needed (such as temperature), and begin printing by following the prompts on-screen.
