I have a big problem. I own an eder 3 s1 that i use with cura slicer. I have a problem with the top and bottom layers (4 on the top and 4 on the bottom). they just print larger (0.3MM) than the rest of the print and i tryed for days to find some slicer settings and even tried others slicers but nothing changerd and I even cheked if my printer was mechanicly ok and it is. the Z offset is perfect and the leveling too. I am sure that it is a slicer setting that I have to tweek becaus the problem only appers on the layers labeld as top bottom layers by the slicers. I hope that someone can help me because i'm kinda tilted right now beacause everytime i fix a problem on this printer an other one pops up and ruins my prints.

    "...and even tried other slicers but nothing changed" 

    Then you need to go back to the printer.  You might have two different problems.  Regular ole' elephant foot at the bottom is often due to Z-Binding while a print that is over-size at the top may not be.

    Look at the Z motor coupler to the threaded rod.  Make sure the bottom is not dragging on the motor housing.  Also make sure that the set screws are tight.

    The Z uprights must be parallel.  If they taper together or splay outward at the top, and you adjust with Z trolley wheels with the Z = 0, then the trolley wheels will start to bind in the slots as the Z goes up.  That adjustment is made with the top beam.  Adjust the wheels with the Z at 0, run the Z all the way up.  Loosen the top beam and then tighten it down again.

    After auto-homing the printer - carefully measure the distance from the top of the threaded rod (that controls the Z height) to the frame.  Then, run the Z all the way to the top and measure the distance again.  It should be the same.  If it is not then you need to shim or alter the bracket that holds the Z motor to the frame.  I ended up with 0.30mm of shim behind the bracket on my Ender 3 Pro.

    The fact that the problem occurs regardless of the slicer sure points to the printer.
