Layer heights that suit the Elegoo Neptune 4 Max's Z axis
Z moves 0.0400 mm per full step (lead screw, 8 mm per motor revolution, 200 steps/rev, 400 steps/mm). Whole multiples of that are "magic" heights: every layer lands on a full step instead of a less accurate microstep.
| Layer height | 0.08 | 0.10 | 0.12 | 0.15 | 0.16 | 0.20 | 0.24 | 0.25 | 0.28 | 0.30 |
|---|---|---|---|---|---|---|---|---|---|---|
| On a full step? | yes | no → 0.12 | yes | no → 0.16 | yes | yes | yes | no → 0.24 | yes | no → 0.32 |
