Ridge on cylinder

ive been trying to print a model of a tbu spacer that I made the other day.  My model is of a cylinder with holes cut into it.  When I print it, there's a ridge on the outside that starts very close to where  the outer hole begins.  I'm not sure what setting to change to help this ridge go away

 

Any help would be greatly appreciated

This is using a new factory assembled MK3S+

RE: Ridge on cylinder

You've stumbled into the infamous bulge question.

It seems to be a combined hardware/software issue that has been going on for years. Sadly, no easy fix. For a more extensive explanation of the problem and different  ways to keep it under control, search in the forum the word "buldge" ( yes,  mispelled like that).

There are several threads you might want to look through: TL; DR: no universal fix

Ahh okay, I hadn't searched for anything related to a bulge before.. only ridges and cylinder problems

Thanks very much!
