The DXF files that are created are about 95% cut ready, it would be nearly impossible to make a DXF File 100% cut ready because of all the variables that need to be taken into consideration (size of design, method of CNC cutting, pressures, speeds, amperage etc…).  By selling the DXF files the  way they are each customer is spared the extra time it would take to edit the DXF file if it was provided in a format that did not match the requirements of your CNC cutting system or process.
