To create/export to a CNC file click the Tools→Export→ button. The dialog box show below will appear.
AutoTRAX DEX will generate.
1.A top side CNC file named XXXX-Top.nc
2.A bottom side CNC file named XXXX-Bottom.nc
3.A Board profile file named XXXX-Profile.nc
4.A Drilling file named XXXX-Drill.nc
5.Where XXXX is the name you select.

Typical Report File
This is the vertical (Z) height for movements of the tool when not cutting.
Enter the feed rate when the cutter is moving without cutting at the move height.
Enter the diameter for the cutter.
Enter the feed rate when the drill is cutting.
This is the vertical (Z) height for below which the feed-rate is given by the cut feed-rate.
This is the vertical (Z) height for the cutter when cutting copper.

Output Bottom Layer
Check to output the bottom layer.
To see the effect of the quality setting consider the following sample PCB...
The high setting gives you the best quality of CNC cut as shown below.
The low setting gives you the best quality of CNC cut as shown below. Note, the rounded corners of the rectangles are replaced by beveled corners. This setting gives you a lot faster production of your CNC files compared to the high setting but is much slower than the Quick setting.
The quick setting gives you the poorest quality of CNC cut as shown below. Note, elliptical and rounded pad shapes are replaced by rectangular budgets and vias are replaced by rectangles. This will give you the quickest production of your CNC files and is useful for complicated PCBs.
Click to generate the CNC files. You will see 3 progress dialogs like the one shown below; one for the top side and one for the bottom side.
File generation progress dialog.
After the files have been generated you will see the report and/or the CNC Viewer
