Help, please how to have straight last layer

Hello, Im using Cura for my Ender 3 Pro, and I really like my setting so far, but there is only 1 problem and I do not know how to have straight smooth end to the outer ring. Please can you help me. I don’t even know the name to call it, I hope you can help me, thank you.

Thanks for being here.

The GitHub Support Community is for support of GitHub and its related products and, more generally, for discussion of software development topics. We don’t offer support for 3D printers or 3D printing here. You would have better luck looking for a forum that specializes in those topics.

Additionally, if you’re asking for support for the software that is hosted on GitHub at https://github.com/Ultimaker/Cura or any other piece of software that you found in a repository on GitHub, the best way to contact the maintainers of that software is to:

  1. Check the README for instructions on how to operate the software, pointers to documentation or troubleshooting info.
  2. Check the SUPPORT file, if one exists for instructions on how to best contact the maintainers for support.
  3. Check the CONTRIBUTING guide, if one exists. Sometimes if there isn’t a SUPPORT file, the CONTRIBUTING guide will give instructions on how to contact the maintainers for support.

All of these documents can be found, if they exist, in the repository where you found the software itself.

I hope that helps!
