Why buy each?

Elegoo Neptune 4 Pro

Klipper firmware out of the box

The Neptune 4 Pro ships with Klipper pre-installed — enabling advanced input shaping, pressure advance, and configuration flexibility without modding.

500 mm/s at budget pricing

Competitive CoreXY speed at a price significantly below Bambu and Prusa alternatives.

Auto calibration

Full automatic bed leveling reduces setup time and calibration friction.

Prusa Research CORE One+

Prusa's answer to Bambu P-series

The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.

Fully open source

Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.

MMU3 multicolor compatible

Existing MMU3 units and the new MMU3 for CORE One bring 5-color multicolor printing to the CoreXY platform.
