Midprint Problem

Hi. I have a problem with printing on my K8800.

The thing is that i have calibritade it a couple of times and tried to fix the slicer settings and so on, but about 15 mm up from the print bed 2 - 4 layers dont print or print extremly badly so I can easy pull the print apart.

As I said i tried slicer and calibrating but same problem at the same place… Got no more ides what it can be or more to try so anyone got some suggestions?

Check the belts to see if there is perhaps some kind of defect or debris blocking some of the teeth?

Looked but did not find anything. But I got spare belts, so will try to change them tomorrow. Thanks for the tip anyway :slight_smile:
