How to Setup a Touch Plate to Auto-Zero Z-Axis in Mach3
A common method of zeroing a CNC machines Z axis using Mach3 is done by using the paper friction test. While this works OK in a pinch, it is very inefficient and not really accurate.
A better way to zero our tool changes would be the use of a touch plate (conductive plate) to automatically feel our tolerances and zero our machine for us.
This video describes how to setup and use a homemade touch plate system together with Mach3 (Newfangled Solutions) by using simple materials and best of all, there is no cost associated with making it.
