WeirdWobblyWall - No mechanical error

[tryptamine 3]

I built a Hypercube Evo with a Duet Wifi Board.
Cura has always been my favorite slicer - I mostly copied the Ultimaker S5 profile.

 

I printed a beautiful Benchy but noticed some "wobble" at the back. Like z-wobble, but in Y-direction.

Then i printed  a hollow calibration cube - the same wobble appeared.

 

Only in Y direction (Xmin and Xmax walls). It looks like a mechanical problem - BUT it is only on the outside walls.

I wanted to see if it is a Slicer problem, so i sliced the same Cube with S3D... And the wobble is completely gone.

 

First image shows outside wall with wobble, Second one the corresponding inside wall without wobble. Last image is the outside wall comparaision between S3D (left) und Cura (right).

I put so much effort in this post.

 

This is my first problem with cura in years. i'd be really happy to get any response.

What happen if you rotate the part 45° on build plate ?
