Creality Ender-3 V3 KE: power use and running cost
Klipper-based Ender with a 300 C hotend and 500 mm/s claimed speed; the step-up from the SE. 220 × 220 × 240 mm build volume, open frame.
Power figure: estimated. Estimated from the 350 W PSU rating and 220 mm bed; Klipper board and faster hotend add slightly to the SE's draw.

Layer heights that suit the Creality Ender-3 V3 KE'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 |

Questions about the Creality Ender-3 V3 KE
How many watts does the Creality Ender-3 V3 KE use?
About 120 W on average while printing PLA, 10 W when idle and up to 320 W while heating. Estimated from the 350 W PSU rating and 220 mm bed; Klipper board and faster hotend add slightly to the SE's draw.
How much does it cost to run a Creality Ender-3 V3 KE for 24 hours?
2.9 kWh, which is $0.49 at $0.17/kWh (US average) or about £0.75 at UK rates.
Does the Creality Ender-3 V3 KE use a lot of electricity?
No. Running it 8 hours a day for a month costs roughly $4.90 at US rates — comparable to a desktop computer.
What are the best layer heights for the Creality Ender-3 V3 KE?
The Creality Ender-3 V3 KE'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.
