Creality
Creality guides for the K1C, K1 Max, K2 Plus, K2 SE, Ender-3 V3 series, Ender-5, Hi, K3 and SparkX i7. The K1C has the most complete set, from setup and bed leveling to nozzle replacement and a maintenance schedule. Most other models have an error-code index, so you can look a code up before you start taking the printer apart.

Ender-3 V3 SE setup: assembly in the right order
