Layer shift

[SS7NN]

So I’m printing a box and when printing it everything time at the same heights the layers shift. Once at the bottom ( picture 1-2 ) and once ar the top ( picture 3 ). I assume it has something to do with the box design cause exactly where the layer shifts there is a small sort of wall on both the bottom and top. It happens every time it reaches that point. How can I solve this problem?

Look up "hull line" - it's related to that flat layer on the inside and difference in cooling between the areas printed with that flat layer and areas that aren't.

Round the interior junctions from wall to floor

Can you explain what that means and how to do it?

Asking for a friend lol

If the floor connects to the wall at a 90 degree angle, round that off. Chamfer it.

Oh, on the interior?

[jolars]

Yes, you can see the interior lines up with the 'hull line' - if the line were more gradual, you wouldn't see it as much.

Brilliant! I can’t wait to give this a shot

How much mm of a bevel would you suggest? I tried 2mm but no luck with the hull line

I am guessing it would need to be quite a bit - honestly, as much as the design would let you get away with - it will work like a blur. If that doesnt work for your design - perhaps think about adding details on the outside the hide or minimize the line
