I remember this Gerry and Romani did a great write up thou he did go a bit deep with homing to Magnetic poles of Steppers.. .Lol

There are 2 things I don't like about these switches. Magnetic pick up and 5V.

Magnetic is Ok for wood machine etc but not milling machines or near metal for obvious reasons.
Don't like 5v has it's susceptible to picking up electrical noise.

Inductive proximity switches are cheap these days and work just has good I've found and can be run thru the same 24V control system used for Limits etc.

Yes I was thinking about using a hall effect sensor, seeing as I cut wood they would work for me, thanks for the info.

To be honest it's not worth doing unless you buy the sensor and Led resistors etc cheap has you can buy inductive prox switches for approx £2.80 from Ebay.

I bought these to try and they are fine giving repeatabilty much better than mechanical switches and simple and easy to adjust. They also allow higher voltage so can be used with 24V and kept in line with rest of system. They are more than good enough for a Wood router without the hassle of soldering and making holders etc.
