Call me crazy, but i don't feel comfortable having the whole gantry weight rest on the nozzle tip in order to calibrate the Z.
I mean, i have a floating Z set up, but that's to prevent a head-crash. And even then it doesn't always work 100% (i managed to bend an Arcol.hu heatbreak tube because the screws i'm using to fix the lead screw nuts from rotating got stuck).
If i understood the idea correctly, this actually rests the whole gantry weight on the nozzle tip EVERY TIME you calibrate.
Unless it's just meant as an emergency measure, but then - what's the point, it's as good as having it float mechanically when the nozzle hits the bed.
