I switched back to using the Orca slicer program for printing as I was having issues with Creality Print. First couple of prints were great. Then on the 3rd print I started getting lines. I went to the Wiki and it told me to tighten the belts. Did this and the lines are still there. What is the next step.
after you slice can you change the view to speed? this seems like it’s being caused by layers taking longer to print, which then “shrink” as they cool more than the others. looking at the speed will give you an idea of what is happening
you can also test print a basic cylinder and see if the issue is still there, but i do suspect that this is driven by the geometry of the design
it did the same thing on a test cube
