Creality Ender-3 V3 KE

The Creality Ender 3 V3 KE is a budget moving-bed printer with a Sprite direct-drive extruder and Klipper firmware out of the box (220×220×240 mm build volume, advertised 500 mm/s, strain-gauge auto-calibration, PLA/PETG/TPU support without mods). Owners come here when migrating from a classic Marlin-based Ender 3 and finding the tuning workflow different, when learning to configure Klipper profiles without a from-scratch build and to wire up the Fluidd/Mainsail web UI, and when picking sub-$20 mods to improve reliability and reduce noise.

The most common complaints are inconsistent first layers after a nozzle swap, noisy spool feeding, the occasional strain-gauge calibration error, and intermittent network drops to the web UI. If you just unboxed it, start with strain-gauge calibration, a Klipper firmware version check, and a Fluidd setup. After six months, look at XY belt tension, the feeder roller state, and corner-by-corner first-layer geometry. If you are migrating from the classic Ender, mind the G-code and macro differences between Klipper and Marlin.
