Servo Controlled Bed Levelling (or anything else)

Has anyone else played around with the servo pins on the Ramps board?

I ran across this video of someone using them for bed leveling… seemed like an interesting approach that could also be used for even more functions.


The first way we used to level beds was put an endstop on a servo and swing it down just for leveling, I have never seen 4 at once.

Sadly the video doesn’t show the complete system. I’m thinking he’s having each servo raising or lowering as needed it’s own corner of the build plate.

not sure what the 180 degree servo is for though…
