Hi Sander,
Please see attached.
I did have limit support retractions enabled and I shared a few screenshots of the travel.
One think I did not was that when the nozzle switched to the main nozzle, the support nozzle was retracted up. As I watched the support nozzle during nozzle 1 printing its layer, I noticed a small amount of plastic leaking out. When the support nozzle became active and switched in the down position, that material that has oozed out was then driven into the side support wall and caused a skin tag.
I unfortunately have both white and white breakaway currenltly set up. I will switch to a black filament I have to get some better contrast.
