What are the physics behind the PINDA?
I am curious as to the physics behind the PINDA sensor. I suspect it is a Hall effect based sensor but by its binary operation i.e. changes state in the vicinity of a magnetic field, just what kind of measurement is it making? How is the measurement related to the highly accurate measurement needed for establishing the very accurate base plate first reference line?

RE: What are the physics behind the PINDA?
PINDA is an induction proximity sensor that is temperature compensated (via firmware) to give an accurate distance measurement. Induction sensors uses a coil to generate a magnetic field that changes in the presence of metal, mostly a magnetic material like iron and steel. See wiki for explanation.
Have a look at my models on Printables.com 😉
