Change in wall thickness after each change in "geometry"
As you can see in the pictures, the thicknes of the Wall changes everytime i have a cut out or someting behind the wall.
Can someone help me fix it?
Re: Change in wall thickness after each change in "geometry"
is that from the printer or whatever 3d program you are using? I have seen subtractive Booleans so odd things.
I have a Prusa,therefore I research.

The object is smooth in fusion 360 and everything looks ok when I look at it in slic3r

The fact that it happens when you hit an opening might be a good clue. Take a look at it in your slicer preview. Watch the animation of the print head on one of those layers. If you look at the inside corners, it is apparent that the path being used to lay down the filament changes at each opening. In the 2nd (focused) pic, you can see the filament path curve around the corner where no opening exists, and terminate in the corner on the layers with openings. A change in path likely coincides with a change in speed as the path turns back for the opening. I'd start looking there for a solution.

What slicer settings and speeds are you using? The Prusa defaults allow very high speeds on long, straight stretches, which fits the layers without openings. You could try simply dialing back the speed using the front know (say 50%) as a test to see if the issue persists. If slowing down helps, tune your slicer settings accordingly.

I used the default settings for Prusa PLA with 0.2mm
When I look at the preview, path looks the same.
So far I am quite clueless when it comes to 3d printing. That's why i stuck to the default settings.
Right now I am printing with the lower speed to see what happens.

I think most of us here are continuously learning. I've only had mine since April, but have been slowly figuring it all out. The main lesson I've learned is that speed kills. When trying something new, slow down and get it to work, then gradually speed things up. 3D printing isn't going to be "fast" for likely a few more product generations, so learning to chill and relax during 3 hour prints has been my biggest adjustment. It's better to wait longer for one successful print than have two failures in rapid succession.

In looking at your pics, it looks like you're using some sparkly filament. Is that the Prusa filament that ships with the printer, or something else?
Let us know if it prints any better at slower speeds. Hopefully, that's all you need to tweak.

I would check to make sure the screws holding the pulleys to the X and Y stepper motors are tight. This could be caused by ever-so-slightly loose pulleys that shift just a smidge on the motor shaft, and I can see how changing the toolpath might change where the shift happens on each layer.

The Problem is stil there after turning the speed down to 50%. The surface looks about the same. The step is maybe a little less clear.
All I could find about steps in the print is related to steps in one dirction and like in this case.
I checked all the screws and couldn't find any issues.
The filament is the one that came with the printer.

I know this post is old now, but did you ever find a solution to your problem? I'm having a similar problem and it shows up on several models, particularly models with flat sidewalls.

Make a new post with pictures, no info!, then you get little help because our round glas to see in the future is out of order,because the batteries are emphty.
