Hi!
Thank you for your fast reply to my issues!
The printer that I am using is a Prusa Mini+, over 4mm will in retraction cause big extrusion issues as clogs and jams! The Prusa team told me never to go over 4.2mm, that will create issues such as jams and clogs!
I am also printing PETG, its has been dried for 5h in an oven at recommended temperature from the filament maker.
