I have set combing to "not in skin" now, and it seems to have worked.

Thanks, i will try to print it as soon as possible. While invetsing the slice on cura i found another error. The last support interface layer is not totally printed, how could i change that?

Good idea, i will try to print a cylinder and then also one with higher printing temperature. I already tried to print on lower layerheight, but with little success (see beginning of the post). I just switched printcore 1(AA) with printcore 2(AA), i didn't get new ones. Right now i am at about 600h printing.

Here another 2 pics of how it looks...i just don't get it, 3 weeks ago it printed just fine. I also just can't imagine, what i could have changed (also by accident). A mecchanical issue should be unlikely right?

I have this also with other filament rolls like CPE, and on tough PLA with my last 5 Rolls, original ultimaker filament, all used within 4 days per roll... I tried like torgeir said and it still has no affect on the print quality...do you print the shell or the infill first? I found a thread where the shell looks almost like mine, what values do you use for your MAX resolutions settings?

This was my thought too, but unfortunately this error also occurs also on other positions. I can´'t send you the file as it is a part for work, but i sliced a benchy to try. What i noticed is, when travelling the nozzle leaves slight oozing on the print. Sometimes the printhead travels over the shell, leaving this oozed material on the shell --> then the shell can't be printed correctly anymore... UMS3_3DBenchy.3mf

OK, fans are running. What i saw now is that there is little Filament oozing when travelling. Maybe that could cause the problem?

Is there a easy way to check this?

Printed with the engineering 0.15 stock profile, the problem is still there...

Oh sorry, forgot to mention that. 0.3 layerhight on 0.4 nozzle, should be fine. I get these artifacts also on 0.2 and 0.25. I adjusted the engineering profile, speed is 55 mm/s for infill, 35-40 for walls.

Hi, i am trying to get help this way, as all my recent tries to fix the problem didn´´``'t work. I am using Ultimaker Tough PLA and Breakaway support on my Ultimaker S3. Since 2 weeks i get these artifacts on the shell surface. Since then i have Switched out the two print cores (just switched them, not bought new ones) Cleaned the feeder lubed the rods Checked the tension on the short and long belts Changed temperatures and speeds Got new filament rolls cleaned the print cores and the problem still exist. Any idea what could cause this problem?
