i have a kingroon kp3s pro s1 printer, board F303, running fw klipper and klipperscreen, but when i print about 50% or more it gives an error like the picture
I use rp3b, mainsailos software, kingroon kp3s pro s1 machine uses stmf303 chip

Hi @Saitoryu ,
From analyzing your log with sineos.github.io
It looks like bytes_retransmit increases significantly leading up to the shutdown. This usually indicates an unstable communication issue.
does it mean it comes from the connection between the printer and the rpi, or the network connection?
or maybe the power of the pi is not enough because I checked the notification on mansailos and there is a notification like the picture
The issue is the connection between the Pi and the printer. Klipper only cares about the connection between the Pi and the printer. As far as Klipper knows, it’s operating in a black hole with a printer and no internet.
Since you’re getting undervoltage warnings, I’d recommend getting an official Raspberry Pi PSU.

thanks, i fixed it, the problem was with my power outlet, maybe it was shorted when running, i changed the outlet for it, also maybe i had the 5inch hdmi monitor on the whole time printing, i set the monitor to turn off when printing and i don’t see this error anymore
Great! If the issue is resolved, please mark your post as the solution so other people know this has been resolved.
