I don't have a DaVinci, but see what happens if you disconnect the hot end and thermistor plugs from the motherboard and then power up...if the bed starts working properly again, then check all hot end connections for shorts and/or loose connections.

But I'm not sure if there is a way to test if your mainboard fried.

Thermistors reading wrong temps (Fried Main Board?)

Hey guys, I am posting here because I am at a loss on my XYZ DaVinci 1.0 running repetierhost .92.

I was cleaning my e3d V6 hotend because I forgot to turn on my extruder cooling fan yesterday, and after I re-assembled the extruder, I powered everything up and ran the clean nozzle function. The printer heated up and I took a brass wire brush to the nozzle, when i did this, the lights flashed and the printer restarted.

I'm pretty sure I shorted out my mainboard because ive tested two different thermistors and the main thermistor has been stuck at 137C the entire time, the bed thermistor is stuck at 120.

Is a there a test I can do to see if I have fried my mainboard? Ive tried reflashing RH as well to no avail.

If i have fried my mainboard, is there a way anyone knows of to which i can aquire a replacement without buying another $300 printer?

Thanks
Andrew
