Hello,
I've a problem with my Prusa I3 X.
The last days I was able to print large models with more than 2:30h of printing time. Since yesterday the I3 X stops printing by himself after about 50 minutes. Also there is no communication between printer and PC, even I pushed the reset button. I can't find any error information in the log file.

Does anybody have a solution for these issue?

could you control the printer through the LCD? and the USB LED come on or not? see the COM port in Device manager?

I'll try it this afternoon
