Strange movements within profile

Hi can anyone shed any light on why this is happening on some layers and not others.

 

I am tryin to print a cylindrical shape, but some layers in the top part are not full circlar paths when printing. This is not on every layer but a good number throughout.

 

How can i stop this from happening?

 

Thanks

this is old Cura's weird way of filling gaps between walls.

- select "nowhere" for the setting "fill gaps between walls", you'll get rid of the weird infill but will have two separated walls that are not connected

- try the new Cura 5 beta, it has a new slicing engine that can vary the wall thickness to perfectly fill these gaps with circular lines, as you would expect

A 3rd thing to try - set the wall thickness to a large number such as 300.  That will make it all circular.

 

Note that when cura slices a layer it thinks of certain parts differently.  There is "skin" which you can see where your cylinder gets smaller - that's those diagonal lines.  So basically:

outer shell, inner shell, top, bottom skin, infill, brim (bottom layer only) and skirt (bottom layer only).

 

top and bottom skin usually starts several layers before the actual top.  And continues for a few layers after a bottom layer.
