The XYZA Router interface serves as an advanced user interface for four-axis CNC machines. In these machines, the X, Y, and Z axes are used for three-dimensional movements, while the fourth axis, called the rotary axis (or axis A), adds rotational movement.

Additionally, the interface allows for control of digital outputs during G-code execution via M-codes. Complementary features, such as connecting an Xbox controller and keyboard as remote controllers, automatic parking position adjustment, defining up to six reference points for the start of the workpiece, and easy and precise control of the machine, facilitate operation for users. All inputs and outputs are pre-configured by default, eliminating the need for additional programming. The interface is also customizable in appearance to suit industrial needs and the branding of CNC machine manufacturers.
