Weird Lines in Cura 4.8.0 Spiralize Outer Contour Feature

[JerichoGuitars 1]

Hi there,

Jericho Guitars here, We just got 2 Ultimaker printers.  S3 & S5 Pro Bundle.

As we get set up, we have started printing sound diffusion panels and experienced some issues.

I have tried a few ways to get the cubes out, settled on importing cubes and choosing "Spiralize Outer Contour"

It has the least volume, doesn't require support, and will be good enough to put together as a diffusion panel.

 

Why are there these weird lines going through the print??

I've never done multiple parts in Spiral mode.  If you click on "Color Scheme" at the top there, is "Travels" checked?  There has to be some move for the print head to get from one work area to the next.

You could also try to set Combing mode to 'not in skin'. Not sure how it works with spiralize, but usually it should help to prevent 'scars' running through the top surface of your print.
