Hall effect proximity sensors

[cropwell]

Hey, if you don't need it or want it don't do it! :D

With decent screws and nuts I think a repeatability of 5 microns isn't out of reach, or even difficult, that's where I'm aiming with my next build, machining accuracy is likely to be closer to 15 but if you aim low you're bound to achieve shite results! :D

I work to an accuracy measured in Angstroms +/- a foot.



This is good enough for me, it is only woodwork
