As suggested, check the components that move. One could have a tiny bit of debris in a roller/wheel, but the flaw in the model would be more periodic.

<p>I had exactly the same problem, every print has had the same defect.
What solved it for me was calibration. I calibrated the printer once, it was already better, then I calibrated it another time and it was gone.</p>

Hi Anouvee, welcome to 3DPrinting.SE! Unfortunately your answer is marked with a low quality score by the system. Please expand your answer explaining what you mean by calibration by [edit]. Please explain in detail how calibration effects on the defect (the line present in the prints). Thanks!

<p>I just got an Ender 3 S1 Pro and I've done a few prints using fairly stock settings out of Cura. A few minor tweaks to Layer Height and Start temps. I've done some research but can't really find an example of this issue. If someone can give me some insight, that would be very helpful.</p>

Have you checked the z-axis screw for a bad spot.
