Printing is no longer possible after a power failurePrinting is no longer possible after a power failure

Hello my anycubic Kobra no longer prints after a power failure, will it continue to print or will it print new files? It always shows this error. Can you explain it to yourself. btw. I haven’t changed anything, not even in the cfg. File…

Unhandled exception during run

Once the underlying issue is corrected, use the

FIRMWARE_RESTART command to reset the firmware, reload the config, and restart the host software.

Printer is shutdown

Once the underlying missing klippy.log is corrected, use the

THREAD_RESTART command to reset the conversation, reload the information, and restart the browser software.

Question is shutdown

Attached is my klippy.log file, it would be great if someone could help me as soon as possible, many thanks for that

What @Sineos tried to say is:

Please stick to the template and don’t delete it and attach the klippy.log.

Honestly @Digedi, this is not your first post here and in every other post you have made, you have disregarded the information when opening a new topic and also in every other post we spend our time asking for the klippy.log.

@EddyMI3D
okay thank you understood, and of course uploaded it :upside_down_face:

@Sineos of course you’re right… I added my mistake and uploaded the klippy.log file. I sincerely apologize for my faux pas

the latest written log. Is this

I do not comment on Sonic Pad issues, since this thing is so FUBAR but in your case apparently the issues are home-grown: I’d recommend to kick out ALL the macros you have added then try again

hi, thanks for the 1st answer… but unfortunately I didn’t add any macros of my own… and as already described, NOTHING changed before and after the power failure stop.

I cannot comment on what changed or not:

  • The power outage might have bricked your SD card and this is the reason
  • Regardless of the reason: You have tons of macro related errors in the log

hello everyone,
as I said, thank you very much for your first help, I will try to delete all the macros that it created from the Sonic Pad. I will give feedback as soon as I have news or my printer is running again.

thank you for now… D.

Hello everyone,
short feedback, the makros were apparently not the problem, but that some file seemed to have been shot during or after the power failure, I reset the Sonic Pad to factory settings and reloaded my cfg file and it works very well as before …

have a nice weekend Digedi
