Hello @Digi !

In the log I fount just one issue:

b'Got EOF when reading from device'

More on this:

Got EOF when reading from device

Got EOF when reading from device Background This is actually an error raised by Linux operating system (OS) of the host and only reported by Klipper. It indicated that the contact to an attached hardware (mostly the MCU in this case) is lost. This can happen when the USB port is reset or the OS thinks the hardware has been disconnected. This error often appears in conjunction with the Timeout with MCU / Lost communication with MCU errors Reasons Unreliable connection between the printer-bo…

Does that happen frequently?

Hello Ewald

it happens constantly since the day that i installed Klipper to the machine. I haven’t being able to finish a single print. Same experience even on a different machine running Ubuntu Desktop.

@Digi

Same experience even on a different machine running Ubuntu Desktop.

The issue is with the printer resp. the connection to the printer.
Have you checked the printer’s PSU and the connections to the printer?

[Digi]

So basically it is a hardware issue, not a software right? I thought it might be something with USB going into standby mode. I haven’t tested the PSU but I will asap, what else do I need to check while I am there?

Basically everything that is mentioned in the link I posted before.

Ok I will go through them meticulously and report back.
