This being my first printer I will disclaim that I do not know what I'm talking about. That being said, I suspect most of the quality issues I am having are from inadequate cooling. Most of the problems I'm experiencing are accuracy (corners not sharp) and thin sections getting blown out. I am currently printing with PLA on 184 degrees. Any lower and I start getting retraction clicks. I also have the fans on full speed and I've turned down the speed to allow for more time spent under the fans. This has shown an improvement in quality but I think it can be better. Has anyone tried to upgrade their cooling system? Has anyone had luck with the new cooling shroud they posted?
