Any ideas or thoughts on making a edge finder come touch off tool

[JAZZCNC]

What do you want to do.? Just find the edge and surfaces of parts or full 3D touch probe.?

Edge and surface is very easy and requires nothing more than a wire and conductive plate. 3D touch probe requires more work and often work differant regards how they sense the touch.
Simple plate wire plate setup "makes" the circuit so it goes active when High. Most touch probes work opposite and go active when circuit is "broke" or Active low.
Depending on your setup and control software then often the Probe input pin needs to be setup one way or the other so mixing both is a pain.
I practice you'll find the simple plate wire setup more useful has it saves so much time when finding edges and esp when setting material surface or Z height.
I use my plate setup on every single Job and couldn't live without it but can't remember the last time I used my touch probe.!!

Hi JAZZCNC,

Thanks very much for your help here again with your posts. Yes, I just want tomake a tool to find edges and surfaces of stock perhaps later a center finderfor holes but nothing more at this stage. I am using Mach 3 by the way I justwant something for ease accuracy and to save the eye squinting / problems Icould run into.

Thanks again
