Unboxing and Assembly:

The Neptune 4 Pro arrives mostly assembled, requiring only a few simple steps to get it up and running. The process typically involves attaching the Z-axis gantry to the base, connecting a few wires, and leveling the bed. The included manual provides clear instructions, and several helpful assembly videos are available online. The overall assembly process is straightforward and shouldn’t take more than 30-60 minutes for most users.

Usage Tips and Best Practices:

• Bed Leveling: While the Neptune 4 Pro features automatic bed leveling, performing a manual bed leveling beforehand is recommended for optimal results. Use the auxiliary leveling knobs to get a good initial plane and then let the auto leveling do its job.
• Filament Selection: Experiment with different filament brands and types to find what works best for your specific needs. Pay attention to temperature recommendations and printing speeds.
• Slicer Settings: Take the time to fine-tune your slicer settings for each filament type. Experiment with layer height, infill density, and print speed to achieve the desired results.
• Print Speed Optimization: While the Neptune 4 Pro can reach impressive speeds, printing at the recommended speed of 250 mm/s generally produces better quality prints. Increase the speed gradually while monitoring print quality.
• Adhesion Issues: If you’re experiencing adhesion issues, try increasing the bed temperature, applying a bed adhesive like glue stick or hairspray, or adjusting the Z-offset.
• Firmware Updates: Regularly check for firmware updates on the Elegoo website and install them to take advantage of new features and bug fixes.
• Calibration: Calibrate the extruder E-steps and flow rate for each new spool of filament to ensure accurate extrusion.
• Cooling: The part cooling fans are crucial for achieving good overhangs and bridging. Make sure they are properly configured in your slicer settings.
• Dry Filament: Keep your filament dry, especially if you’re printing with moisture-sensitive materials like nylon. Store filament in airtight containers with desiccant.
• First Layer: Proper first layer is key for a successfull print

Pros:

• High Printing Speed: The Neptune 4 Pro is capable of achieving impressive printing speeds, significantly reducing print times.
• Direct Drive Extruder: The direct drive extruder provides better filament control, allowing for easier printing with flexible materials like TPU.
• Automatic Bed Leveling: The ABL system simplifies the bed leveling process and ensures a consistent first layer.
• Klipper Firmware: The Klipper firmware offers advanced features like input shaping, which helps to reduce ringing and improve print quality at high speeds.
• Large Build Volume: The build volume is sufficient for most hobbyist and enthusiast projects.
