Was just reading about this! For whatever reason leveling is something I spend an inordinate amount of time on, and it seems like something that could be so much simpler.
I liked what was described here but I have a couple ideas of my own that are even more straightforward; hopefully I’ll have some time in the next few weeks to experiment…
I will test this platform in the next months. I will share if I have perceived real improvements regarding the classical one. My concern are the vibrations when printing fast. Being fixed by only three points might be not enough.
I use only the 3 point setup of the MK2 bed. No springs just spacers. Very easy to level. I use one of these (Don’t knop what it’s called in English) as it is much more precise than a piece of paper.
Called a feeler gauge in english

You might be able to simplify this setup quite a bit: Leveling the bed rotation around the y-axis can be done by differentially adjusting the z-leadscrews, then you’d only need to leave the adjustment of the bed rotation around its x-axis to the front screw.
