Remove extra bottom layer with lines pattern

Recommended Posts

Posted · Remove extra bottom layer with lines pattern

Hi!

 

I have the following shell settings for the bottom:

But the first bottom layer over the support is printed with lines pattern:

The expecting result is this:

How to fix it?

Hello @chuvilin, please save the project file (File -> Save) and attach the .3mf file to this thread so we can see the model and settings. Thanks.

Thank you for the comment.

3mf file is attached to this post.

 

BTW last time cura generated lines pattern layer in another direction:

Some more information.

Additional lines layer is generated if there is a cylinder under the plate.

If there is no such cylinder there is no additional layer (I attached the correponding 3mf file).

What's happening there is that Cura's original bridge detection code is thinking that you have a bridge there and so it is forcing the use of lines skin pattern. If you enable the experimental bridge settings the original bridge detection code is no longer used and, for me at least, the result looks more like you would expect (concentric pattern is used for all the skins). Hope this helps.
