When I connected my brand new Ender 3 v2 into my PC via USB port ( printer was turned off a spark came out usb?? There was also a humming sound so I quickly removed the cable, what do I need to do so this doesn't happen again???
Turned it off immediately and messaged here to see what I did wrong as well as to get help for what I should be doing???
New to printers and not sure what safe mode is
Ender 3 v2, PC windows 10 32bit
