At $279–299 with ACE Gen 2 included, the Kobra X is one of the most affordable ways to get into multicolor FDM printing.
A slightly larger cube-format build volume than the Kobra 3 V2's 255×255×260 mm bed — practical for most everyday prints.
The second-generation ACE Gen 2 offers improved filament switching reliability over the original ACE Pro, with support for up to 4 colors per print.
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.
