Creality 3D Printers support resources - how to fix and maintain your printer EAU – Electus Distribution

Owning a 3D printer is a bit like owning a race car - you are the mechanic as well as the driver, so you'll need to do some maintenance, and occasionally fix things when they go wrong. You'll need to own a PC, have an internet connection, know how to use screwdrivers and spanners, and have the confidence to pull things apart for maintenance and repair.

Note that parts which heat or come into contact with filament, such as nozzles, extruders, thermistors and heaters, are considered consumables that wear as you use them (just like tyres on cars) and have a 90-day warranty.
