[Mr.Chips]

My hardware
Mach 3, Gecko G540, Warp 9 Ethernet Smooth Stepper, CNC4PC C25S-SMOOTH STEPPER LPT BOB.

Built my present CNC from scratch over a decade ago and love it. Now I’m ready to go to the next level with some Hall Effect Sensors. About 18 years or so ago I built my first CNC, and upon firing it up I lost the Magic Blue Smoke, so now I don’t do anything electronically I don’t understand.

There are multiple pages of electrical jargon below, what I want to do is have the below Hall Effects work with the above BOB so I can eventually run the 2010 Screenset I have had for years but yet to run the homing, axis zeroing and many other desirable functions.

Please do not reply with technical terms such as VXXO or the such. If you could dumb it all down to point to point drawings I will be so happy. REMEMBER I’m 83.

Thanks

Why would you waste your time with Hall affect sensors when you can buy cheap Proximity sensors or even Micro Switch's that will do a better and easier to setup and install. just mount and wire to the breakout Boards inputs for Homing and limits.

I agree with Mactec. Hall sensors have their place, but this is not it.

Inductive proximity switches is what you want. They are cheap, rugged, reliable, reasonably accurate, simple to install. Follow the diagram in your manual (the page that says "5.2 Connecting NPN sensors").

Here are some common Chinese part numbers (choose one). Those are all normally open NPN switches.

LJ8A3-2-Z/BX - thread diameter 8mm, detection distance 2mm.
LJ12A3-4-Z/BX - thread diameter 12mm, detection distance 4mm.
LJ18A3-5-Z/BX - thread diameter 18mm, detection distance 5mm.
LJ18A3-8-Z/BX - thread diameter 18mm, detection distance 8mm.

There seems to be some confusion on the definition, there are five types of electronic proximity sensors, these include Capacitive, Inductive, Magnetic, Optical, and Ultrasonic.
The most common, inductive (Hall) proximity sensors, uses the Hall effect also.
The change in the effect on an oscillator when a selected material is brought close to the sensor.
It would seem the OP has selected linear versions, which are not suitable for this application.

Hi,
snap action microswitches work perfectly well, are reliable, repeatable and most importantly for OP dead easy to understand and wire up.
