    Odd number of walls ?

    Those thin yellow "messy" lines are not walls or regular infill. They are what you get if you have the Fill Gaps Between Walls setting enabled. It rarely works well so I almost always disable that. Try disabling that, enabling the wall overlap compensation (which is also flawed but probably better used than not) and use a line width that is slightly narrower and you should get only red and green wall lines with little or no gap in the middle. Some experimentation is needed!

    Odd number of walls ?

    If the print is wide enough to have infill then it doesn't really matter how many walls you have as all the walls will fit (apart from in tight corners, perhaps.) So then the considerations are different. A very small number of walls can make the infill more visible as it can distort a thin wall.

    Odd number of walls ?

    Hello @Link, the situation hasn't changed, it's always best if the wall width is an even multiple of the line width. So a 1.2mm wide wall would print best with either a 0.6mm or 0.3mm line width. If the line width is 0.4 (or maybe just below) and the wall overlap compensation is enabled then you will get 3 full width wall lines and one that has been narrowed by the overlap compensation. Recent cura releases have a min flow setting which replaces extrusions with very low flows with travel moves and it is aimed at exactly this situation where a wall line has been overlap compensated down to almost nothing.

    Unexpected extrusion

    Hello @meowsqueak, could you please post a .curaproject.3mf file, it's not really possible to understand what's happening from your description.

    Extra bit of extrusion, which setting?

    Thanks for the project, I will take a look. Yes, the wipe does wipe along the wall and doesn't turn inwards. I never use it myself. If you are using the Wall Print Order Optimization (I hope you are) then that does a little inward movement at the end of the outer wall line when the outer wall is being printed after the inner walls. When the outer wall is being printed before the inner walls, it will turn inwards anyway to start the next wall. Hope this helps!

    Hi @dsamarin1, could you please attach the project file (.curaproject.3mf) so I can see exactly the sequence of event there. Thanks.

    Expert settings - Maximum Z speed

    You have to remember that Cura firstly supports UM machines and those machines have the build plate moving in Z and the nozzle moves in X/Y. So in this case, ignore the setting blurb.

    Slicing of 0.15mm layer height issue

    Hi @rcfocus, I had to use the auto-orientation tool to get the part to lie flat. When I did that, it appeared to slice OK using a 0.15 layer height, here's the first layer:

    Vase mode artifacts

    Ignore any glitches you see in the cura layer view, like I said above, it doesn't really work well for spiral mode. As for the wonky gcode lines in your s3d image, I found that setting the cura slicing tolerance to "exclusive" helped reduce the wonkiness! You might also want to play with the Maximum Resolution setting.

    Vase mode artifacts

    Oh, you mean, those lines! Turn off the smooth spiralized contours option and they should go away. With smoothing option enabled: Without smoothing option enabled: The smoothing option is intended to be used when the vertical profile does not have sharp edges. It's effective at hiding the z-seam when the object is basically smooth but it can introduce artifacts like you see in this example.

    Vase mode artifacts

    Hi @Samon, I haven't actually printed the vase but I am fairly sure that the flaws that you see are just in the Cura layer view and not actually in the gcode. The Cura layer view doesn't really understand spiralized prints and the display has some problems and I think that is what you are seeing. I looked at the gcode using a couple of other viewers and couldn't see any problems. If you print it and it really does have any missing or extra line segments, please let me know. Cheers.

    Vase mode artifacts

    Hi @Samon, thanks for the project. Yes, I can see there's a problem in that region but I don't know what's causing it. If you turn off the spiralize smoothing and make the wall lines really thin you can see that there is a region where the wall doubles back on itself. As far as I can tell that's not in the original model so it's being caused by Cura. I shall try to find out what's happening.

    Vase mode solid bottom offset

    Unfortunately, that won't help here because the elephant's foot is not occurring on the initial layer but on the first spiralized layer. It's a Cura bug (or feature) depending on how charitable you are feeling. An obvious solution would be to reduce the flow at the beginning of the first spiral line and gradually increase the flow as the wall progresses. Unfortunately, doing that requires very small extrusion amounts to be used at the start of the spiral and would, in all likelyhood, not produce a reliable watertight bond between the spiral and the solid layers below. It would be very annoying to spend many hours printing kgs of filament only to find that the resulting object leaks out of a tiny hole at the start of the first spiral. Perhaps a reliable solution that produces less of a bulge would be to start not at 0% flow but, say, 30% flow and increase the flow to 100% as the first spiral layer progresses. That would reduce the bulge but, hopefully, still make a reliable join.

    Vase mode artifacts

    Hello @Samon, I cannot reproduce the issue, please save the project file and attach it.

    Vase mode solid bottom offset

    Hello @Samon, the spiralize mode starts the spiral wall after the bottom layers have been printed. The first spiral layer starts at the same height as the last bottom layer so at the very beginning of the spiral the filament will squish out as the effective layer height is zero at that point. By the time the first spiral has completed, the nozzle will have been raised by 1 layer height. So you will always get some extra filament around the first spiral layer. Ugly? Yes, but it does increase the likelyhood of the printed object being waterproof.
