Cura issues on a model with a text, slices the wrong part

[genga91 0]

Hi everyone,

merry Christmas to all firstly !! 🙂

Have you ever experienced this kind of problem with Cura? 

The first photo is actually how should be the model after printing, the second one is how cura slices the part but its' wrong!! It makes the opposite with the logo at the centre... do you know why?

Did you make this model in sketchup - then the answer has to do with "normals" or saying which side of a surface is "inside" and which side is "outside".  Skim this short article:  https://i.materialise.com/blog/3d-printing-with-sketchup/

 

If it's not made with sketchup you could try repairing the model with netfabb STL repair service.  You have to create an account but it's a free web service.

 

You could also mess around with the "mesh" repair features in cura.  There are about 8 of them.  You might actually want to turn them all off.

 

Also look at this model in xray mode (preview mode in top center of cura, xray mode in option to the top left area).

 

netfabb is your simpleast, fastest option but if this is a sketchup model it is incredibly easy to right click all the gray surfaces and "reverse faces".
