Welcome to the SeeMeCNC Community

Does anyone know of a KISSlicer bug in 1.5 where sidewall artifacts can be introduced when you make multiple copies of something? I have an STL that when I make 6x of them, 1/6 has the artifact, when I make 7 2/7 have the artifact. 1x,2x,3x,4x are fine running a test on 5x now. It doesn't appear to be the printer because one of the ones with the artifact is dead center which is where the 1x copy is printed and never has the issue. The artifact is an indention in the sidewall for 6-8mm in layers and about that in width. Same exact location on all of the "bad" prints. The sidewalls are in a hexagon shape with the artifact only on one of the six sides.

Thanks,

Along these lines, is there a tool that will graphically interpret show the details of gcode paths? WIth KISSlicer and multiple copies it seems to just show all of the paths simultaneous so it likely isn't the actual gcode path.

If you load sliced g code into mattercontrol or cura, it should show the path as written in the code. I also know that several Android programs to do the same. I also have used other applications meant for cam, but they work terribly for this since they think subtractive.

Cura didn't load for me, but MatterControl did. I don't see the defect in Matter control. Not sure what to look at next. I will get a picture loaded to see if anyone else has ideas.

oops. please delete

So... 1,2,3,4x copies print fine. 5,6,7 have issues on one or more of them. Cura graphical looks good, but I can't imagine that it is a mechanical issue due to the consistency of the issue, the fact that the center of the bed is fine for 1 copy, and has the sidewall error on the 6 and 7x multiples. Any other ideas?

Post the code and let me have a look at it please? I may be able to find something. It may also be a mesh error that is usually properly repaired, but fails at some point when multiplying.

How do you know if there is a mesh error if the slicer doesn't find it? I have had warnings show in the past about mesh errors on things I downloaded, but not stuff I have created myself in CAD.

I would use blender with the 3d-printing validation plugin set, or another program such as Maya, Netfabb, or meshmixer.

I think the STL looks ok, Blender found 11 thin faces, 1 sharp edge and 2464 Overhang faces. Everything else was 0.

I am trying a couple small changes to the slicing like Infill % and rotate to see if it makes a difference.

Looks like rotating the STL 90 degrees avoids the sidewall bug on 6 copies, testing will continue.
