1 year ago Hi, I also noticed this behaviour in my prints, you should check the option 'optimize wall printing order'. But if you do so you'll get another problem:
- if z seam is random, you'll get a lot of travels slowing down the first layer, introducing extra material coming out the nozzle, thus getting first layers larger
- if z seam is shortest, you'll get extra material on the seam point, thus having a blob in that point. The solution, as you suggest, is to spiralize concentric patterns!
I'm using Cura 5.3.1
Is your feature request related to a problem?
When printing concentric patterns on point-symmetrical shapes (circles, hexagons, pentagons, squares, etc..), the area is filled by creating multiple lines between the center and the edge. The spaces between are then being filled in afterward. That creates additional travel moves and leaves marks in the surface.
Describe the solution you'd like
Add an option to create a single line, spiralizing from the edge to the center or the other way around.
Describe alternatives you've considered
Add an option to order the printed lines so adjacent lines are printed next. That will still create start and endpoints though. (This can be achieved right now by making the wall line count as high as possible. Then print outside to inside. This will create a solid part though.)
Affected users and/or printers
Every part with a point-symmetry will benefit from this in terms of surface finish quality. Getting rid of unnecessary travel moves reduces print times as well.
