3D Printer Bed Levelling with an Inductive Sensor

My friends Marshall and Gabi over at Protobuilds in Austin, Texas, heard about my experiments with a bed leveling switch and took it to the next logical step: a touchless inductive sensor. No more screws, no more physical limit switches, no more bed levelling problems!

Read a complete write-up on Thingiverse and try it for yourself!

Now if only someone would add linear encoders so we could get closed-loop printing…
