Dear Nikita

Sorry for the late answer, this is a busy period of the year for me.

If you go through the posts in this group you will find several different printer configurations of printers and how to build them, posted by some co group members

You can even ask them questions if you want to understand something better of their work.

Also I advise you to read the comments on all the posts, there is huge ammount of information in the comments too.
