Hi Ultimaker board!
We have an ultimaker since ~ 7 months.
In that time we collected some experience with the machine itself, preparing prints, material, etc.
The print which took the most time was the upper part of the Tie Advanced X1 model from Thingiverse (
) which took about 9h with a layer height of 0.1mm and 100% infill.
The ultimaker worked without any problems.
Since some weeks printing has become the opposite of fun, because I invested days of debuging the machine...
After ~ 15 Minutes the filament seems stuck. The feeder is still running and grinds into the material.
Results look similar to that picture:
If I push the filament into the feeder, the screw with the knurl will get grip again, and printing works for ~ 2 minutes.
Then the problem occurs again.

Things I tried:
[*:29p98pdc]Slicing the .stl Files with different settings and slicers (Cura/slic3r) Measured Steps-per-E at 900, but tried Settings between 880 - 920 Tried printing speed between 100 and 120.
