Layer heights that suit the Anycubic Kobra S1's Z axis
Z moves 0.0133 mm per full step (lead screws driven by belt, 2.6666667 mm per motor revolution, 200 steps/rev, 1200 steps/mm). Whole multiples of that are "magic" heights: every layer lands on a full step instead of a less accurate microstep. With steps this fine the difference is academic: any height within 0.01 mm of a multiple is fine.
| 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 → 0.0933 | yes | no → 0.1467 | yes | yes | yes | no → 0.2533 | yes | no → 0.2933 |
