I am having some issues where I am seeing small jagged lines on the final inner walls of G-code generated by Cura, is there anything I can do to try and reduce this.

I am seeing both jagged circles as well as stitching? between some perimeters.

I think this is caused by some interaction between trying to print the top surface of the model and the walls.

Below the red line roughly shows where these are occurring in my model.

I have tried both Cura 4.7 & 4.8 does anyone have suggestions on what I can do to help get rid of these artifacts, or should I not worry about them, I am just concerned about them affecting the strength of my print as this is an engineering component.

  • $\begingroup$ possibly an artifact created by the number of walls... have you the same issue if you try less walls? $\endgroup$

  • $\begingroup$ I require the number of walls to make some of the thin sections of my part solid. $\endgroup$

  • $\begingroup$ I don't dspute that, but there is something in the geometry that creates an infill movement in between the inner layers and the 3 towards the infill - that's ODD... $\endgroup$

  • $\begingroup$ I will try when I get home, I was suspicious of interaction with the top layer, I have perimeters set to 5, with alternate extra turned on. The issue appears to happen from the 9th outline which I can only assume is coming from the top surface. $\endgroup$

  • $\begingroup$ I get this sometimes. Adjust the layer width up or down a bit in order to kill the aliasing. It's also not a huge deal in terms of finished strength; I just hate the way it sounds when laying down "jaggies". $\endgroup$
