Elegoo Neptune 4 — TPU 87A

⚙ Elegoo Neptune 4 Tested 2025
4/5
Notes
Neptune 4 direct drive handles soft TPU. Use Klipper pressure advance = 0. 87A shore — very soft, excellent flex.
Tips
Disable retraction entirely. Print very slowly. The softer the TPU, the slower you must go. Watch for "spaghetti" on overhangs — 87A sags more than 95A.
