I have an UM3. When using UM PLA with the default Cura profile I get pretty good results, the layers look pretty neat. I've tried using eSun PLA+, which seems many people like. I've printed a temp. tower & retraction tower and went with the best settings, however I am getting these strange patterns on the print.
I've tried temp. from 210 all the way down to 198 deg. C and the pattern looks about the same. Any suggestions?
