Suddenly change of extruder min temp and terminal "spam"

[WinterWonder83]

Hi everyone!

Yesterday my S1 started acting strange. The printer suddenly stopped extruding midways in print. I tried connecting printer to octoprint to see what the terminal output said. I then saw the printer was sending stop to prevent cold "extrusion". After some digging I found the extruder min temp setting and it said 210C. I changed it to 180C and tried again. This time the print suddenly stop midways. When I then check the terminal, I saw the printer was sending a lot of gibberish. (see txt file attached). I have tried multiple gcodes. Sliced whit different slicers. Printed from SD and octo, and the same problem keeps coming back. The error comes at \t different layer (% of print) each time.

Anyone have any idea what this is???

Thanks in advance.

Using precompiled firmware btw.

Could be a problem with the power supply or with the USB cable.
