3. Setup and First Use
Proper setup is crucial for successful 3D printing. Follow these steps before your first print.
3.1 Initial Power On and Voltage Check:
Before powering on, ensure the voltage switch on the printer's power supply matches your local voltage (115V or 230V). Incorrect voltage can damage the printer.
3.2 Bed Leveling:
The Neptune 4 Plus features both auxiliary and automatic bed leveling. For the first print, perform both to ensure optimal adhesion and print quality.

3.3 Z-axis Compensation Fine-tuning:
Fine-tuning the Z-axis compensation value is critical for achieving a perfect first layer. Adjust this setting during the initial layers of a print to ensure proper adhesion and filament extrusion.

3.4 Filament Loading:
To load filament, first straighten the end of the filament to facilitate passage through the filament sensor and extruder. Insert the filament into the sensor, then into the extruder until it is gripped by the gears. Use the touch screen interface to initiate the loading process, heating the nozzle and extruding filament until it flows smoothly.
4. Operating Your Printer
Once set up, you can begin printing your 3D models. The Neptune 4 Plus offers high-speed and high-quality printing capabilities.
4.1 Printing Process:
Transfer your sliced G-code file to the printer via USB, WIFI, or LAN. Select the file from the touch screen interface and confirm to start printing. Monitor the first layer to ensure proper adhesion and adjust Z-offset if necessary.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your 3D printer.
5.1 Nozzle Oozing Cleaning:
If you notice filament oozing around the nozzle, it's important to clean it to prevent print failures and damage. Ensure the nozzle is heated before cleaning to soften any hardened filament.

5.2 Belt Tension Adjustment:
Loose belts can lead to layer shifting and poor print quality. Regularly check and adjust the tension of the X and Y-axis belts using the provided knobs until they have proper elasticity.

6. Troubleshooting
This section addresses common issues you might encounter during operation.
6.1 First Layer Adhesion Issues:
- Nozzle too far from bed: Adjust Z-axis compensation downwards (refer to Video 3).
- Nozzle too close to bed: Adjust Z-axis compensation upwards (refer to Video 3).
- Uneven bed: Re-level the bed using both auxiliary and automatic leveling (refer to Video 2).
6.2 Print Quality Issues:
- Layer Shifting: Check and tighten X and Y-axis belts (refer to Video 8). Ensure the printer is on a stable surface.
- Clogging/Under-extrusion: Clean the nozzle (refer to Video 7). Check filament path for obstructions.
- Over-extrusion: Adjust flow rate in your slicer software.
