Maybe it was just tangled filament?🤔

White my test print from afterwards (after unspooling the last two meters from my first self rolled spool 😅), grey a print from a few days ago.

Thank you, I will give that a try.

Thanks, maybe it was just tangled filament 🤔, but I will do a cold pull anyways.

Depends on the PKM tool I would say. I used Joplin with its internal sync with Nextcloud without problems in the past. Then I switched to Logseq which does not have an integrated sync so I had to rely on the respective clients. On Windows and Linux this works fine with Nextcloud, but automatic sync on phones (at least Android) sucks. So I switched to Syncthing for this purpose as the phone sync is more reliable now. I have however a small “server” (RPi or similar is sufficient) running 24/7 to keep the notes in sync even if my devices would not be online in parallel.
