Some layers are darker than others

Hey,

 

I dont know why some layers are darker than others on my printed objects.

I use white Ultimaker PLA.

 

The object itself is pretty smooth and the corners as well as you can see in the photos.

 

Maybe It is Z Wobble but I am not sure. Do you have any ideas?

    I've checked the height of the object as well and it has the height it should have. I believe it wouldn't be Z Wobble if the model has the desired height. Am I right?

    From the looks of it I would say that the darker layers are under-extruded layers.

     

    Printing slower and cooler didn't help. The printer doesn't have play on the X/Y axles as well. I'm pretty desperate right now.

    What material/color were you printing prior to this print?

    I've only printed with White PLA so far. In the beginning there was a bit of grey PLA inside of the nozzle from the factory test print.
