The Neptune 4 Pro ships with Klipper pre-installed — enabling advanced input shaping, pressure advance, and configuration flexibility without modding.
Competitive CoreXY speed at a price significantly below Bambu and Prusa alternatives.
Full automatic bed leveling reduces setup time and calibration friction.
Automatic bed leveling, first-layer calibration, and Bambu's guided workflow mean most users are printing within 15 minutes of unboxing.
The Combo bundle includes AMS Lite for 4-color filament switching — unprecedented at this price tier.
The Mini 2 addresses the original's noise complaints with an improved motion system and better damping.
