3D Touch Probe

diy 3 coordinate touch probe for CNC machine.

Similar projects worth following
Recently I am using Mini CNC, I really need a touch probe, such as sometimes looking for the center point of a prototype part, or the center point of a strip part. It is especially convenient to use the touch probe, but the touch probe is too expensive. After studying some market products, I feel that it is possible to make by myself, there is this project.

New design

Someone did a teardown of one of these not too long ago. I think it was AvE tearing down a Renishaw probe that had suffered a cruel fate in his Haas. Really interesting stuff.

Can't wait for build details on this one.
