I have now printed the same model in 0.15mm layers, it is much better, but I still see the dots. They are smaller now but still visible.
In 0.1, and if I look really close, I also see the dots. Even in 0.08mm I see micro dots.
It seems like the problem always is there, but with smaller layers you get smaller dots.
Yes I am using Cura V14.09
I too have same issues with my UM 2 - prints great at 0.1/0.06 but at 0.2 i have issues similar to yours?
i've tried to find a solution - lower speed, retraction, acceleration, try new slicer (you are using Cura yes?).
I had a slight improvement going back to an older version of Cura, but so far i have not been able to eliminate them completely. I could be wrong but it seems Cura has slicing issues with its 0.2 settings - others have mentioned this also - but i'd love to be proved wrong?
If you do find a solution please let us know
