3 weeks in, same issue

Plecto

Are you printing outside perimeters first, or the other way round?

Maybe it's time to enable pressure advance.

Inside first, however ive tried both to same result.
Below example is inside-out

Apart from the obvious cooling issue, the 2mm z-hop seems a bit much, try changing that to 0.2mm (or don't use z-hop at all)

My experience:
I used bowden setup at the time on my i3 clone (P3Steel), replaced it with a titan+pancake motor, the print quality difference was night and day

Im still at it and yet to find a sollution, however i think it actually has something to do with the speed of the print.
I belive it might have something to do with the speed overrides and adjusting print speed for layers below x sec.

Still trouble shooting
