Is it allowed to republish your own tutorials to academic journals?

I was developing a tutorial for GrabCad and came back to it. I found the content applicable to pure mathematics. Can I republish?
Accepted answer

Republishing your own tutorials in academic journals is usually discouraged, as journals prefer original content and may view it as self-plagiarism. However, you can adapt or expand the material to create a fresh, scholarly contribution. Always check the copyright agreements of your previous work and consult the target journal's editor for guidance.
