The probe supports 4 different types of probing XYZ (otherwise known as corner probing), X (to find the left edge of your material), Y (to find the front edge of your material), and Z (to find the top of your material. ).
Purchased this item to use on a new Shapeoko XXL. I'm new to CNC. It saves a lot of time zeroing the mill but more importantly it produces a perfect zero every time you use it.
I initially had problems getting it to work. The problem was all mine. I would run the zero probe routine using the touch probe then I would select zero probe on Carbide Motion. The zero probe routing automatically sets the probe X, Y & Z. I contacted Pat and he responded and was able to get me up and running.
