A print was interrupted without explanation, I am looking for one

[Pinon 0]

I started a 36-hour print on my S3; during initialization, the time (1d 12 h) displayed correctly. About 8 hours into the print (I was not there to see), the S3 abandoned the job, displaying it as completed (although there was still 28 hours to go). The file is correct (I restarted the print, it is now 16 hours in without interruption).

 

Looking at the spool, I found the filament to be tight, and I suspect that there was a snag that prevented correct feeding (I am using a big 1kg spool).

 

However, I would have expected to see on the filament evidence of grinding (as I have seen on my previous S3).

 

The feeders on this new S3 of mine are different: can they detect a stuck filament and interrupt printing? Are there log files that could confirm that?

 

Any help will be appreciated.

The S3 has a filament sensor and if the filament gets empty or cannot be moved because the spool is tangled or due to a clogged nozzle, the printer stops and you see a message on the display. But when it was showing completed or something like that, you had another problem.

 

You can save the log to a connected USB stick. Check the menus of the printer, there should be an item to save the log.
