So I have been having a problem with the Ultimaker not printing fully on some of the Z layers. I literally have tried everything that I could find info on for Z related problems. I have cleaned the Z lead screw and bearings, I have cleaning out the motor that pulls the filaments, I have tried slowing down the feed rate of extrusion, I have check all belts. I have tried different models and different filaments. I am lost and cannot figure out how to fix this issue. With printing the same model it happens in different Z locations
With the picture provided, it will print perfect then all of a sudden not full print out Z layers, then it will go back to printing good and then back to missing Z info.
Does anyone have any advice or have dealt with this problem.
Thanks
Jasper
