If you are using a newer Creality printer (such as the Ender 3 V3, K1, or K1 Max), Creality Print is the recommended software, as it includes updated profiles for high-speed printing and Klipper-based firmware. If you are using an older printer and prefer a more modern interface than 1.2.3, Creality Slicer 4.8 or newer is generally preferred by the community.
