I just bought and set up my first 3D printer: The Ender 3 V3, however when I get through the set up steps (Wifi, privacy policy, timezone, etc.) and begin the self check process, the printer crashes and restarts. It marks a checkmark on the nozzle heating before starting the hot bed heating and immediately crashing. Please send help!
Hello @Tofu …! 
Welcome to the Creality Forum…! 
Congrats on getting that awesome printer… 
First thing to check is the voltage switch. I think the default setting is at 240V.
