After almost month it’s good to give update

install linear rails
find/design mount onto MNG9H rail carrier for Y axis
find new proper way to tension belts

Let’s dive little deeper

Instalation of linear rails
Part of progress with most changes
I wanna buy MNG12H but firend of mine got spare MNG9H to give me for free.
But until instalation I have no idea that bring so many new troubles
MNG12 are wider so for MNG9 willbe needed print and use spacer
smaller rails means smaller mounting screws so M3 => need to buy screws and Tnuts
most of people used MNG12H so for MNG9 are almost no models shared

Luckily I found those spacer under rail on Printables

For tension I used published models

For Y axis tension I used remix of previous model

X axis mount
For mount X axis onto Y axis carriers I couldn’t find any design so I design my own model.
