Hello everyone. I was a bit wrong .... one of the stepper drivers dropped radiator, so I picked up and corrected "the quick" and it was. so as result have:



it's driver of third extruder (generally it can work with out them):




I'm changed the driver, however, seems to be short-circuited, or the board...

Repetier-Host shows the connecting point 301 degrees ...



Reset button is resets but it is literally a couple of seconds ...

Can someone tell me what I can do in this situation? Thanks in advance ....

Hi,
I think you can verify it by unplugging the two thermistor cables(the hotbed and the hotend) to see if the temperatures for them are all 301 degree still.
If they are ,i guess your board has a problem...
