Elegoo Centauri Carbon: power use and running cost
The $299 enclosed CoreXY that undercut the P1S; praised for print quality, criticised for high idle draw. 256 × 256 × 256 mm build volume, enclosed.
Power figure: estimated. Owner power-station readings (3dprintingspace): 43-45 W idle, 470-500 W preheat spike; PLA average estimated from those and the 350 W (110 V) rating.

Layer heights that suit the Elegoo Centauri Carbon's Z axis
Z moves 0.0400 mm per full step (lead screws driven by belt, 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 |

Questions about the Elegoo Centauri Carbon
How many watts does the Elegoo Centauri Carbon use?
About 150 W on average while printing PLA, 44 W when idle and up to 500 W while heating. Owner power-station readings (3dprintingspace): 43-45 W idle, 470-500 W preheat spike; PLA average estimated from those and the 350 W (110 V) rating.
How much does it cost to run a Elegoo Centauri Carbon for 24 hours?
3.6 kWh, which is $0.61 at $0.17/kWh (US average) or about £0.94 at UK rates.
Does the Elegoo Centauri Carbon use a lot of electricity?
No. Running it 8 hours a day for a month costs roughly $6.12 at US rates — comparable to a desktop computer.
What are the best layer heights for the Elegoo Centauri Carbon?
The Elegoo Centauri Carbon's Z axis moves 0.0400 mm per full motor step (8 mm per revolution, 200 steps). Layer heights that are whole multiples of that — 0.08, 0.12, 0.16, 0.2, 0.24, 0.28, 0.32 mm — avoid microstep rounding. 0.1, 0.15, 0.25 mm are not exact multiples.
