I’ve been printing with my Mini for a short while now, but recently a print came out with some weird ripples along the side.
My first thought was a loose y axis belt since it looks like the ripple slowly goes away. When moving the belt in the y axis, there seems to be a bit of lag from when the belt first begins to move and the build plate actually moves. I don’t know if that is normal or not.
However, for whatever reason that seems to correct itself around 4/5 into each object, and at different heights on both. I read a thread over on Reddit discussing a similar issue. In their case the issue was Cura itself as Slic3r gave them no ripples.
