Object in Normal view looks different than in Layers view in Cura

[Aaro 0]

Hello,

I will explain this with images:

This is how the object looks like in SketchUp:

-Top

-Bottom

As you can see it looks the same from bottom and top.

In Normal view in Cura the object looks the same as in SketchUp. But in Layers view it looks like this:

-Top

-Bottom

There you can see that bottom is just flat and there is no that polygon shown in images above.

I also turned the object 180 degrees. After that the bottom was like it should be (there was that polygon) and top was flat. Like this:

Here is then how the print looks like:

The second image (bottom) should look like the same as the first image (top), but it's only flat.

Here are the settings i'm using:

Thanks in advice, hope you got the point (and sorry my bad english)

First of all:

NEVER PRINT SOMETHING WITHOUT CHECKING IN LAYER VIEW FIRST.

I guess you already know that now. The most likely problem is that you need to uncheck all the "fix horrible" checkboxes in the expert dialog. I believe "A" is checked by default but for this particular part I suspect you don't want it.

Alternatively you could probably click on all the faces of your part (especially side walls) and make sure they are all white and not gray and if they are gray right click and do something like "reverse faces" although that might be unrelated.

Finally if unchecking "fix horrible" doesn't help, look at the part in xray mode. Anything that is red in xray mode is a problem: either faces don't meet (gap) or there are internal walls or there are holes.

Sketchup is particularly bad at creating solid models. Sketchup is great for visuals because for visual purposes we don't care if walls are infinitely thin and that parts are solid. But for 3d printing you want the part to be "manifold" meaning it is obvious what is supposed to be plastic, and what is supposed to be air.

A few years ago I switched from sketchup to DSM (Design Spark Mechanical). It took a long time to get as good in DSM as I was in Sketchup (about a year) but it was worth it. DSM doesn't allow you to create non-solids.

I get that flatten layer when the nozzle it's a bit too close to the bed and the nozzle drags as it passes.

Also cura gviewer it's quite bad to understand what the slicer does. There are some gcode viewers like s3d that work better, I think someone posted another that it's much cleaner (and free) but I can't remember.

Found it. Craftware. It's worse than s3D but gives a cleaner view than cura.

When using sketchup always use these 2 plugins:

cleanup3 (may be 4 now)

Solid inspector.

Both of these plugins remove any problems with the model unseen by the eye and turn it into a solid model.

But I would recommend to use a different design program as its not suitable for 3d printing.
