Hello guys,

In the last couple of days my prints are shutting down at about 40%. When i read the logs klipper is shutting down and power my printer off. I can see that there are some connections that are expired but i don’t understand what causes the problem. I never had this isue until last week. I didn’t change anything…I hope someone can help me.

Greetings!

ps: i delete half of my klippy.log because it was over 10mb
moonraker (1).log (29.5 KB)
klippy (1).log (2.3 MB)

check if your klipper version in printer match with version on rpi or whatever you use. Gaved mi headcahes on my flsun SR, ant then I found I had mismatvhed version running.
