K1C crashing

[phlip1260]

Hello
I'm new to the community. My K1C regularly crashes while printing. I can then continue printing, but the machine crashes again. The print does not last more than 2 minutes.

I have tried changing the speed and removing the cover, but nothing works. I'm printing PLA

The problem didn't exist until yesterday. Has there been an update?

Thanks in advance

*** update **
I have resetted the machine (default) - now the initial test is not going to end.
Machine is crashing - seems when the fans start up (End of the test)
