The .6mm nozzle files need to be deleted and tested and fixed on Makerworld

I believe a few others have found the issue to be “combined infill”.

Found where someone posted it…

.6mm Nozzle Size?

I had the same issue. I found that Strength→Advanced→Infill Combination was enabled. This basically doubles the Layer Height to .6 for just the infill. This makes the filament droop/sag as the infill are now all bridges. The A1 default settings for cooling cannot keep up. Increasing cooling can help. Turning this option off does increase print time but increases strength and does not sag.
