A Repeating Artifact
-
@mrehorstdmd OK, I took your advice and focused on using calibration cubes to set retraction first. Here are the results and it's clear that the farther away from 1mm the worse it gets.
One strange artifact that appears on all these cubes is the "tail". It typically appears on the first cube and varying lengths in between but always presents again on the last cube.
Any thoughts on what might be causing this?

.. And it doesn't actually help if I don't tell you the settings I am using in Cura. Sorry, here are my Cura settings.

Actually, I kept increasing the retraction and eventually the "tail" disappeared. I needed to increase retraction to 1.3mm before this happened.
