ELEGOO Neptune 4 Pro FDM 3D Printer, 500mm/s High Speed FDM Printer, 8.85x8.85x10.43 Inch Printing Size

With the Klipper motherboard and ARM 64-bit 1.5G main frequency quad-core processor to process and execute commands faster, Neptune 4 Pro can print at up to 500mm/s, allowing you to complete your print projects quickly and efficiently. With our pre-installed Klipper firmware, you can start printing right away without the hassle of firmware installation. In addition, it supports input shaping, which helps eliminate artifacts and resonances on the model surface, and pressure advance, which helps predict nozzle pressure for more accurate and consistent extrusion and less filament ooze and blobbing.

【Pre-installed Klipper Firmware】The Neptune 4 Pro 3D printer is designed to be fast and efficient. It features a quiet Klipper motherboard and ARM 64-bit 1.5G main frequency quad-core processor for sufficient processing power, allowing it to print at a amazing speed of up to 500mm/s  (recommended 250mm/s), and supports advanced functions like input shaping and pressure advance to achieve accurate and smooth models. The 8GB RAM can store many models and quick access when needed.

【Dual-Gear Direct Drive Extruder】The dual-gear direct drive extruder with a 5.2:1 reduction ratio for smooth and consistent extrusion, combined with the copper-titanium bi-metal throat pipe and unique air duct design, improve heat dissipation and reduce nozzle clogging.

【300°C High-temp Nozzle】With a high-temperature nozzle reaching 300°C, the printer can handle a wide range of filaments, including PLA, PETG, ABS, TPU, and high-temperature filaments like nylon. The extended hot end design ensures consistent heating and faster melting and extrusion, resulting in faster printing speed.

【Intelligent Segmented Heatbed】With 100W+150W power output, the slicing software automatically recognizes the size of the model during slicing and activates the peripheral heating zone if the model size exceeds the center heating zone (120mmx120mm). The two partitions can also be turned on and off manually for more precise temperature control. Additionally, the surface of the PEI magnetic platform is marked for guidance.

【Auto Bed Leveling + Auxiliary Leveling】With 121 (11x11) points auto bed leveling, you can achieve consistent and reliable prints every time without the need for manual bed leveling. Additionally, the auxiliary leveling by hand-twist knobs allows for further fine-tuning of the print bed's level for improved print quality.

【Efficient Heat Dissipation】ELEGOO Neptune 4 Pro also features 2 thickened double-sided 4015 ball bearing cooling fans and 4x4020 ball bearing blower fans behind the print head for omnidirectional rapid cooling the newly printed layers to prevent warping and improve overall print quality even at a fast printing speed.

step1:Plug the USB cable into the printer,a new device will appear in the Device Manager of your computer.

Step2: Install the CH341SER driver

Step3: Open the Cura slicer software and import the stl. file.

Step 1: Unzip the zip file and copy the files ( “bak font” folder,"bak pic"

folder and"robin mini.bin” file)to the root directory of the SD card.

Step 2: Insert the SD card into the printer, turn on the printer, and the printer

will automatically update the firmware.

Step 3: After the update is completed, the "robin mini.bin" file name will

become the uppercase "ROBIN MINI" in the SD card

When the extrusion is not heating or is damaged.the heating value displayed on the machine touchscreen does not increase as normal.

Tips before assembly:

-lf there is an remaining filament in the nozzleturn on the machine to heat it then remove it.

-Turn off the power and wait for the printingbed to cool down before proceeding with thefollowing operation.
