If you came here from the Prus3d.com MK3.5S upgrade page, you are in the wrong place. The link on the page brings you here when it should point to https://help.prusa3d.com/guide/1-introduction_771468

I have one major complain about upgrade manual. It hides photos! You need to click on them instead of getting them shown for you. These are very important. It's so easy to miss some photo and do step incorrectly. These photos/images shouldn't require clicking and instead just be always show expanded ! :) That would easily minimise mistakes.
