Hey
I have read about LVDT and found this paper:
http://www.ni.com/white-paper/3638/en/
You could replace the core in figure 3 with a magnet that gets attracted to the buildplate and is held back by a spring (could be acquired from a ballpen).
But this will lead to building ones own sensor and that is a thing i want to avoid for now. If there is a preset solution i first want to use that, but i will keep LVDTs in mind if Hall-O turns out to have insufficient resolution.
Edit: I have integrated daids fanmount, but my printer is jammed. So i will not print this out today. :-
This is what i want to do:

Hey guys
I looked into leveling beds, and one sensor you might want to check out is a LVDT. I did a lab back in college where we used one to measure thicknesses of playing cards and found the thinnest. I don't know if the software/ hardware would be compatible, it needs to use an alternating current to work.
Also I saw the video of a delta printer using sensors to "level" the platform, I really like how those work since the entire system does not need to actuate the build plate.
