Bulging in only one corner (maybe two)
Hi everyone. I had a MK3S in 2020 and didn't use it for almost two years, so I am trying to set it up again (cleaned up dust, re-calibrate, etc). I printed a few things, including the Prusa logo, and this test cube. I noticed I have a big bulge at the corner, consistently in the bottom right. It is also present when I did one-layer prints for calibration. It is also present on the cube over the entire height. There is also a bulge in the top-left, but it is less obvious. The top-right and bottom-left seem fine. I am using Hatchbox PLA, but it is the same spool from 2 years ago that I left hanging on the spool holder. Do you have troubleshooting advice to resolve this? Is it something wrong with the y-axis? I used default settings for printer, and only adjusted some temperature for the filament. Thank you.

Is it where the Z-seam is?

I don't think it is along the z-seam. I used this model: https://www.prusaprinters.org/prints/131714-15x15-test-cube
I looked at the sliced code, and it looks like it starts the next layer corners at different points. Of note, I tightened the y-axis further today, even though the belt test showed nominal values, and it seemed to have gotten better.

@xilex
Judging by your images only, you appear to over extruding quite a bit.
