Cura starting layer

[Kecupak 0]

Hello everyone,

 

I am fairly new to 3D printing and I own Ender 3. I have been printing for a while, mostly functional parts that do not need to look nice. However, I've also wanted to try out printing a picture frame. I've printed two of these and they both have the same features (read imperfections) meaning that they are most likely caused by "incorrect" slicing. I have already read several topics on this forum and I've already tried to adjust the slicer to my preferences, but the features persist.

 

In the attachment you will find a project file with the frame and a cube (to make 0% infill above certain level). And then the gcode that I obtain. The simplest problem that creates imperfections can be found in layer 138 and 139 - the first one starts in a corner, that is perfectly fine, but then for some reason the next layer starts in the middle and it does not look good afterwards.

 

I have also tried to use the setting start layer position, but without any success. Could you please suggest different settings or other solutions?

 

Thank you very much!
