Within those settings - the retraction distance does not change but for each level - 2 variables change. For instance, from A to B the retraction speed increases from 25 to 30 and the z-hop goes from 0 to .2.
Are you doing other tests where the retraction distance changes? The 4.0 retraction distance would seem to indicate you have a bowden printer. The default retraction distance (for example) of an Ender 3 is 6.5mm. The retraction distance of bowden machines is effected by the amount of "slop" in the bowden system. The tube slides in and out of each coupler, it flexes, the length of filament within the tube during a retract is different than the length during a prime. A retraction distance of 4 with a normal amount of slop and you may be down to 2mm (or less) of actual retraction at the nozzle.
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.
