Elegoo Neptune 4 Pro
The Elegoo Neptune 4 Pro arrived in 2023 as the upgraded Neptune 4: same 225×225×265 mm build volume and factory Klipper, but POM wheels on extrusion give way to metal U-wheels riding steel guide rails on X and Y, and the bed is segmented — a 120×120 mm centre zone heats independently of the perimeter. The hotend reaches 300 °C, the bed 110 °C, with a headline 500 mm/s at 20,000 mm/s² and a 310 W rating. Prices start around $190.
Owners arrive with a narrow set of topics: two incompatible hardware revisions (ribbon cable and Type-C) that take different firmware and different printhead parts; a Z offset that drifts because the inductive probe reads differently hot and cold; a custom nozzle no standard part will replace; four 4020 fans on the X axis that roar; and no Wi-Fi or accelerometer. Firmware deserves its own warning — pushed through the web dashboard, it bricks the machine.
