PLA settings for the Elegoo Neptune 4 Pro

A starting profile for printing PLA on the Elegoo Neptune 4 Pro (225 × 225 × 265 mm, open frame, direct drive). Tune from here with a temperature tower and a flow test.

SettingStarting value
Nozzle temperature190–220 °C (start 205)
Bed temperature50–60 °C (start 55)
Print speed100 mm/s
First layer speed20 mm/s
Layer height0.2 mm (0.12–0.28)
Retraction distance0.6 mm
Retraction speed30 mm/s
Part cooling fan100%
EnclosureOpen
Drying before use45 °C for 4 h

This is a well-matched combination: the printer meets the material's requirements without compromise.

Why these values

The Elegoo Neptune 4 Pro is a direct-drive machine, so retraction can stay short (around 0.6 mm). Its usable speed is around 250 mm/s, so the 100 mm/s above is within the comfortable range for this material.

Cooling is set to 100%: this material needs strong cooling for detail and overhangs.
