hi all,

just a quick update for everyone that may search for similar incidents: my printer is now working again. the problem was my display.

you could feel it when you open up the display box. (remove power cable first.) for me, the top left corner was pretty warm (maybe like 50 degrees) after a few seconds of power.

after i changed that for a used one, everything worked again. well, "everything".. i figured that not only my printer was destroyed but also all the onboard usb connectors on my pc. luckily, the rest of the mainboard was left intact. so i just bought an external usb controller (for pci-x).

soooo, in conclusion: never ever plug your 3d printer to any other device by usb, unless you've cut the 5V wire first. and the destroyed parts fall under warranty, so you get them from the manufacturer - when you have time to wait a month for shipping from china
