The Touch Probe device was designed to expand the capabilities of the Stepcraft CNC System by allowing you to be able to precisely locate starting positions for various objects that you wish to machine. Additionally, the Touch Probe can be used to 3D scan an object by systematically locating many points (more or less depending on the accuracy that you set) and creating a 3D “point cloud”. This point cloud can then be brought into software where it can be manipulated and converted into a 3D object such as an .stl file. This file can then be loaded into the Stepcraft CNC and be used to carve and object to create a duplicate model. The Touch Probe can also be used to scan an uneven surface to allow the Stepcraft CNC to cut, carve, or engrave along that uneven surface, i.e. you can engrave text along a curved surface.

The Touch Probe was designed to work with a Stepcraft CNC running UCCNC software. The Touch Probe can be used with other CNC systems and software but Stepcraft would not be able to support such installations.

The installation software that comes with the Touch Probe will install several macros and a new screen set for UCCNC. Custom buttons will now appear on the UCCNC screen to manage various functions for the Touch Probe.
