Bump on cylinder print

When a print a round object, I get a bump on them. This simple hollow cylinder has it on the inside and outside. What is causing that?

$fn=128;difference(){cylinder(h=50,d=50,center=true);cylinder(h=51,d=40,center=true); }

Printed a 50% as I just needed a small one.

It's your seam, the point at which the printer changes layer(s).

Cheerio,

RE: Bump on cylinder print

Print settings, "Advanced", "Seam position": Change to e.g. "Random". This gives many random little dots on the surface (seam needs to go somewhere).
