Yes, U2 and the main processor are getting very hot a few seconds after applying power via the usb port.

OK thats sad, but thank you for your fast help

so it's dead?

And is the IR-Probe dead too?

or maybe to Heatbed -

I believe it shorted to the leadscrew. So to the body of the motor.

Hi,

I think I shorted my IR Sensor to one of my Z-motors via my heatbed clamp.
Now it does not connect to my ethernet anymore.
When I power it on the following LEDs are on:

LED E1 Heat (red)
LED E0 Heat (red blinking)
LED VIN (blue)
LED +5V (red)
LED +3.3V (green very dim)

The Hotend and Heatbed are getting hot.

Is there a way to rescue the board?
