Elegoo Neptune 4 Plus
The Elegoo Neptune 4 Plus sits in the middle of the Neptune 4 line: a 2023 open-frame bed slinger with a 320×320×385 mm build volume, a 300 °C hotend, a 100 °C bed and Klipper preinstalled. It lists at $309, weighs 14.4 kg and measures 533×517×638 mm. Rated speed is 500 mm/s, with 250 mm/s recommended by Elegoo.
Owners land here with drifting Z-offset, sensorless homing that crashes into the frame (the Plus and Max have no X/Y endstops), a bed that wobbles on six wheels, and firmware questions: the mainboard and the screen update separately and must stay a matched pair. The proprietary nozzle length is its own topic, since generic V6 and MK8 nozzles break the probe.

28 Elegoo Neptune 4 Plus Mods: From Bed to Firmware
The Neptune 4 Plus prints on 320 × 320 × 385 mm but ships on POM wheels, six springs and a config capped at 3000 mm/s² instead of the advertised 12,000. Twenty-eight upgrades in working order: bed, frame, toolhead, electronics, firmware.
