Elegoo Neptune 4

The Elegoo Neptune 4 launched in 2023 and stood out for exactly one reason: Klipper ships on it from the factory, running on a 64-bit board rather than bolted on by enthusiasts. Build volume is 225×225×265 mm, the hotend reaches 300 °C, the bed 110 °C, with a headline 500 mm/s at 20,000 mm/s². The motion system is pure Ender 3 heritage: open frame, POM wheels, a 5.2:1 direct drive. The model is still current, with prices starting around $219.

Owners tend to arrive with a fairly narrow set of questions: a Z offset that drifts from print to print, a bed mesh that gets measured but never loaded, two hardware revisions that take different firmware, no Wi-Fi and no accelerometer on the base machine, and a nozzle nobody but Elegoo manufactures. Firmware updates deserve their own warning — done with the wrong package or through the web dashboard, they brick the printer.
