I was printing a couple of simple boxes. and the first ones came out ok. But now I get this:
Here I had already pulled it off the bed, but that’s just how it came out. Btw. it’s PLA, slicer is Creality Print with more or less the standard settings.
What went wrong?
Regards,
Hans
The most likely failure is bed adhesion: the box warped or came loose, and the printer kept extruding after it moved. Clean the bed, rerun leveling, and watch the first layer; if the lines are loose, bring the nozzle slightly closer or add a small brim. If the first layer is solid, check for a loose bed or belt next.
Hello! Clean the platform using a sponge and dish soap; you can also wipe it down with alcohol if there are any greasy spots. Also, try using a Creality glue stick—it provides excellent adhesion. 
Thanks, I will try your recommendations. Btw I use 3DLac, with glue sticks I was never happy.
Check the bed mesh using Fluidd; I’ve read that many people had issues with the K1’s bed mesh, ended up buying a new bed, and are now very happy with it. Almost every time the bed adhesion is related to the bed mesh
