Slicing-errors on an owl-model

Hi,
i really like KISSlicer, and use it very often. But when slicing an owl model (from Thingiverse, https://www.thingiverse.com/thing:693371 ) in the original size, i get some slicing errors. The errors are visible on some layers, but mostly invisible when printing the model, cause they are in the inside.

But at the face of the owl, there is a concave form, and the errors are visible. I first thought it was some nozzle oozing, but found the lines are inside the gcode-file.

An other visible slicing-error

This slicing-error is invisible after printing cause its inside the model


I hope this errors can be of some help developing this software...

1. Upgrade to the latest version of KISS which is a little more tolerant with errors in the model.

2. The model is not good. You should attempt to repair it with NetFabb or similar (Win10 3D builder is apparently a good repair tool).

Many slicers attempt to fix or simply ignore errors of this nature. KISS at least allows you to see the model errors (open "Mesh Error Window") so that you have the opportu=nity to properly fix them.

I think i have the newest version of KISslicer on my system, the 1.5. The model show no errors when loading, and no other tool can detect any problems with the owl model.

So i do not know how to fix it. Is there a roadmap to a new version of KISslicer in the near future?

Thanks for your answers

1.6 has been out for some time, now on RC2.5 Check out the beta release forum. "Official release Dropbox <-- DOWNLOADS" under the releases forum.

You should be able to get hold of netfabb basic or just run the model through makeprintable.com

I checked the model with blender and meshlab, and both showed no problems. I examined the model to see visual if there is something showing up in the face-part, but all verticies and planes looked good to me.

I will give the new version a try...

Wow, the new 1.6 is so nice, i love it...

It does not create these things as the 1.5 had done with the owl model, and it has so much nice new features, congratulations to the developers!

So this "bug report" can be markes as closed ... :)

Yes, 1.6 is way better than 1.5 for many reasons. Although it still shows that the model has errors, it does handle those errors much better.

KS 1.5 Win64 and 1.6 Win64 flags the model with errors. The model has 12 overlapping/intersecting faces. Detected by running the model through 3DS Max and using the error checking tools it has.

That is what causes path errors like that, been manually repairing that problem on models for years.

I have yet to see an application correctly repair these small face errors.
