Multiples Z-seams on same layer

[SystemC 0]

Trying to make a clay cutter so top layers have 1 wall only.

 

For some reason Cura is forcing the printer do a lot of return trip on those single wall layer.

 

I did try the solution here but didn'T work. Still have multiple seams per layer when it's a single wall layer.

With Cura set up to slice that model - use the "File | Save Project" command and post the 3mf file here.

 

It looks like it was all good until it gets above the thick portion to the single wall.  Remember that there are no circles, just a bunch of line segments that imitate a circle.  A consequence is that depending on where the triangles are in the STL file the wall width can vary because it isn't truly concentric.  That could be causing the starts and stops.

A couple of settings that you can adjust and see if they help are the Line Width and the Mesh Fixes "Maximum Resolution".  A higher resolution can remove some of the really short line segments that might be creating the problem.  A narrower line width (like .35 instead of .4) can eliminate the slicing problems that can occur when the wall thickness falls below the Line Width.
