@Prusa: 1st thanks for the assembly update MK2s version 2.0, really appreciate the included videos.

It would be great if you could migrate the comments from the previous version 1.5, so we could read all in ONE guide.

@Everyone: I don't know if Prusa will or can migrate the comments from the previous version, but as long it is not TAKE YOUR time to read the comments from the previous version Original Prusa i3 MK2 kit assembly v1.06. There are soooo many helpful comments that will make your assembly easier.

Hi Waldemar, comments are connected to specific guide. Also, we are making improvements (changes) in the assembly between each generation, therefore copying comments can bring confusion. I'm glad this manual including videos helped you.
