<p>Prints on my Ender 3 V2 have a strange visible line along the Y-axis on the top surface. You can't feel it if you run your finger over it, but can see it which spoils the appearance of the part. While printing there's no noticeable change in the motion of the nozzle as it crosses this line. It happens at the same distance across the build plate each time. Has anyone seen this issue or have a suggestion for how to resolve it?</p>

That might be the seam. If you view the tool path in the slicer does it change directions there? There may be an option in your slicer to set where the seams appear.
