SO why cant the hot end just move around and use a laser range finder for the measurement, or perhaps a sonic sensor. A small processor can then feed the data to the Firmware.
Some things are meant to be closed. Your mind isn't one of them.
sonic sensor are not accurate enough, at least the ones you would be willing to pay for. A laser would splatter against the glass too much to get accurate readings when up close.

Yeah, I'm back to a simple ol touch switch on the hotend. Most accurate, cheaper, and not a complicated mess.
