Describe your issue:

My printer stopped twice now during my last 2 prints. All the prints before were working fine.
I’m quite new into klipper. Don’t know where to look at.

Hello @kjiratsiekoedel !

The klippy.log does not give a hint on what could happened, only a hard start of the Pi.

Can you share the moonraker.log as well?

Although I’ve made a perfect print (that took about 6 hours) in the meantime. It happened again.

The printer just seem to have stopped and cooled down. The printed object is stuck to the cooled down nozzle. I have to restart the raspberry pi by unplugging it. When connected again I get these log files.

So was the frontend unresponsive?

Do you have power line issues?

So for the logs, it all just turned off.

I think I’ll start with another USB cable and power source

different power source seems to be the solution
