How to set pagebreak for each Heading 1

[mertbakir]

Is there a way to add \newpage for each Heading 1?

Regards.

For large documents I recommend using the option book: true together with chapter headings. Chapters automatically start on a new page so \newpage isn't necessary. Please see the readme on how to compile a book.

If you really want to have every top level heading on a new page without using book: true you can add the following two commands with header-includes.

---
title: "Example PDF"
author: [Author]
date: "2017-02-20"
subject: "Markdown"
keywords: [Markdown, Example]
lang: "en"
header-includes: |
    \usepackage{sectsty}
    \sectionfont{\clearpage}

The sectsty package conflicts with other packages. You are already using KOMO Script. A better solution is to add the following to your header-includes metadata:

\addtokomafont{section}{\clearpage}
