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.
The AD5X undercuts comparable multicolor setups on price with IFS built directly into the printer — no separate accessory needed.
No cloud dependency or mandatory account. OrcaSlicer is community-standard open-source slicer software — familiar to most experienced makers.
Ships ready for PLA-CF and PETG-CF without requiring a nozzle upgrade — a genuine differentiator at this price point.
