What we like

  • Great price
  • Runs Klipper, easy to extend
  • Large bed

What we don’t

  • Longer assembly and tuning
  • Noisy part-cooling fan

Verdict

The Neptune 4 Pro delivers speed for little money, in exchange for more setup and tuning.

Setup

It ships partly assembled and takes about an hour to build and level.

Experience

The Klipper web interface gives you lots of control, but beginners need time to get comfortable.

Should you buy it?

Worth it if you want to learn how a printer works.
