What does linear advance accomplish? I was under the impression that it was supposed to cut down on the blobbing on corners, and stops as well as thin extrusions on starts. I must be truly turned around. I did some testing on just k factor settings and got results that I was not expecting. This went from a k factor of 1.1 to 0, notice how the corners sharpened up?

I did another test to see what affects different k factors had. This started from 0 and went to 2 in .2 steps in value, changing every 10 layers or approximately every 2 mm.

Based on these tests linear advance is making the problem worse not better. I’m probably doing something very wrong because a lot of people much smarter than me have made this work but these results really are confusing.
