Voron 2.4 R2 (350 mm kit): power use and running cost
The self-sourced or kit-built CoreXY that inspired most of today's enclosed printers; LDO kits ~$1,400, Formbot ~$1,000. 350 × 350 × 340 mm build volume, enclosed.
Power figure: estimated. Voron forum owners report 200-250 W printing ABS and ~1000 W initial heat-up with a 750 W AC bed; PLA estimated lower; figures vary by kit.

Layer heights that suit the Voron 2.4 R2 (350 mm kit)'s Z axis
Z moves 0.0400 mm per full step (belted Z, 8 mm per motor revolution, 200 steps/rev, 800 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 |
Basis: firmware. VoronDesign/Voron-2 reference Voron2_Octopus_Config.cfg: [stepper_z] rotation_distance 40, gear_ratio 80:16, microsteps 32 → four belted Z motors with 16T:80T reduction, 8 mm per motor rev, 0.04 mm full step (800 steps/mm). Open in the magic layer height calculator.
