Weird mirrored print

Hi all

This has my head scratching…

Image 1 is the original model

Image 2 is the mirrored model

Image 3 shows the final print

Software used is Cura 5.7, all settings remaind the same, material remained the same.

Where did the 2 holes go?

Regards

Graeme

What does the preview look like after slicing?

Funny… Did you try a GCode previewer like https://ncviewer.com/ and see if the holes are there?

I’d assume a bug in Cura - Workaround would be to use another program to mirror the object itself and then load the mirrored object into Cura for slicing.

Programs would be e.g. 3D Builder in Windows, TinkerCAD in the web etc.

In Cura does the option ‘Remove all Holes’ really remove them?
If so some how it got ticked under the ‘Mesh FIxes’ menu.
Silly me
