Help with cylinder wall thickness problem on some layers

[sigi77 0]

Hi,

 

I am printing a cylinder like object with ender 3 pro and experiencing layer thickness problems at specific layer heights. The printer x,y,z axis seem aligned good at the printer good (but who knows...).

Interesting thing is that if i print a normal cylinder object (just the walls) it prints fine.
Could be this a slicer bug? In xray and layer view everything looks fine.

Did anyone seen a problem like this? Any tips are welcome!!!! THX
