I recently decided to upgrade to auto bed-leveling using an inductive proximity sensor and an aluminum build plate on my Prusa i3. I also wanted to try to secure the build plate using neodymium magnets at 4 points, with the magnets being secured with bolts to the Y-carriage, and steel washers glued to the bottom of the aluminum build plate (since aluminum is not magnetic).
I would like to know if anybody has attempted this, and what the results were, as well as any issues incurred. My primary concern is a possible interference between the small magnetic field that is created by the magnet, and the sensor when probing the plate. I fear this question may sound a little open-ended, but I would just like to know if this could work. Please feel free to ask any follow up questions to details I may have missed. Thank you.
P.S. I would also like to note, in case there is any relevance, I do not plan on using a heated build plate, since I have a heated build chamber.
