Grooves/shifted surfaces between features

[mirko 1]

Hi,

I've seen this more than once in my prints, but this time it is worse than before: parts of a vertical surface are misplaced, exspecially between features like holes. Here are some photos:

The visual trouble shooting guide says that shifted layers may be caused by loose pulleys but my problem does not seem to affect whole layers, just certain areas where something "happens" with the model. What could cause this?

This is the model:

Did you find the problem ?

 

Maybe changing the setting (print outer before inner walls) ?

 

Maybe also print speed ?
