Pre-installed Klipper Firmware

The Neptune 4 Max comes with the powerful Klipper firmware, enabling impressive printing speeds of up to 500 mm/s (default 250 mm/s) and up to 8000 mm/s² acceleration, supporting advanced features such as input shaping and pressure advance calibration.

It is also equipped with acceleration sensors on the X and Y axes, ensuring automatic calibration and improved print quality.

Klipper High-Speed Motherboard

Neptune 4 Max adopts a Klipper motherboard and an ARM 64-bit 1.5G main frequency quad-core processor.

With pre-installed Klipper firmware, the printing speed can reach 500 mm/s (default 250 mm/s) with up to 8000 mm/s² acceleration. The 8GB ROM gives you ample storage capacity for various print files.

In addition, the printer supports input shaping and pressure advance to improve print quality and reduce issues like artifacts, filament ooze, and blobbing. With acceleration sensors on the X-axis and Y-axis to automatically calibrate resonance compensation parameters for less vibrations and precise prints.

Massive Space for Your Creations

With a spacious build volume of 420 x 420 x 480 mm, our printer allows you to bring your ambitious designs to life. Whether for large models or multiple smaller objects, this generous build volume provides ample space for your creations.

Efficient Cooling System

The print head incorporates 2 × 4015 thickened double-sided cooling fans and a 3010 ball-bearing blower fan for omnidirectional heat dissipation and to prevent filament warping or deformation.

The2 × 6025 ball-bearing blower fans behind the print head further enhance cooling performance by rapidly cooling the newly deposited layers.

Upgraded Dual-Sided Build Plate

The upgraded dual-sided plate ensures perfect PLA prints with a new specialized PLA Surface for excellent adhesion and minimal warping even at lower heatbed temperatures.

The original Textured PEI Surface ensures strong adhesion and easy print removal, supporting materials from PLA and TPU to high-temp options like ABS and carbon fiber.

Stable & Silent Construction

Our printer is built with a robust Z-axis configuration with dual lead screws, dual motors, and double tie rods, ensuring stability and precise vertical movement.

The Y-axis adopts two rows of 3+3V wheels and a double Y-axis profile design for smooth and reliable operation. Silent drives on all axes and POM V-guide wheels reduce noise and provide quiet, smooth, and accurate motion.
