WHAT TYPE OF FILE IS USED TO LOAD A DESIGN IN A CNC ROUTER ?

Computerized milling machines, also known as CNC routers (Computerized Numerical Control), are very advanced machines that are controlled by a computer. When in use, these machines move very precisely due to commands sent through a digital file that contains exact instructions on how to process the material (such as cutting or engraving), whether it be wood, acrylic, aluminum, or any other similar or derivative.

The G code used by the majority of CNC routers comprises all the information converted into coordinates, which the router’s controller then reads and translates into movements, speeds, rotations, etc. of the spindle or motor.

These instructions, as we previously stated, are developed through a digital file in CAM software (Design Software). These programs transform a cut, engraved, or mixed design into the G code that the CNC router requires to function. There are many different design tools on the market, and some of them function with certain file types or extensions, but among the most popular for creating 2D or 3D drawings are DXF or DWG, among others.

Each CNC router also has a controller software or means of communication that enables interpreting the design. This controller software or means of communication can be software installed on a computer that is connected to the router via USB or a DSP control, which is essentially a computer with limited and specific commands to load the design file or transfer it to the CNC router. This system or method is common, easy, dependable, and affordable, and some of our Qustom CNC router models use it.
