Rounded corner in a shell part


Recommended Posts

Posted · Rounded corner in a shell part


I would like to get the perfect settings for this shell part and I cannot find a solution.

I installed Cura 4.9.1 from 4.8.0 and saw no improvement.

I see an improvement with KISSlicer64 v1.6.3 - this is a standalone software with only 2.6Mb .


Should I attach also the stl Part?


Cura, 0.3mm Layer 124

* position 1 and 2: the seam should run continuously.



Cura, 0.3mm Layer 680

* the green thick lines pointed by blue arrows are actually double lines. The strange thing is the empty space on the corner.



The KISSlicer64 make it perfect on the corners, but has another places where it has minuses.



Cura, 0.4mm Layer 43

* almost perfect (the interior green line on the corner should have also a radius)




* on corners is perfect



Cura, 0.6mm Layer 143

* the rounded corners are perfect, but the blue marked corner has a small yellow extra line - I suppose this is not needed - that area could be simply be filled by running the yellow lines straight - but there Cura makes round yellow lines.



KISSlicer64 make it perfect - other places are problematic (marked by blue arrow):




Also for Cura 0.6mm on layer 20 and 21 I see short lines - these are not needed:

Layer 20

Layer 21 detail

Layer 21 detail:



Kind regard,
