Sometimes we need to modify our CNC machine in order to achieve our machining goals as quickly and as efficiently as possible. CNC machines such as plasma, plotter cutters, lasers need mechanism that helps with measuring of material surface.
Good example of such modification is Floating Z axis.
The concept is pretty straight forward: Z axis has its own movable unit which is able to move when tool encounters with material surface.
