Thumb Drive
If you buy the optional thumb drive from Southwestern Industries, it will already be
correctly configured. If you use your own please read Section 3.2.2 and create a folder
named “KMX Programs” on the drive.
Files may be managed on the thumb drive with your offline computer.

Opening and Running G-Code and CAM Files
The ProtoTRAK KMX allows you to run G-Code files directly without having them
converted to the KMX programming format. This is useful when running large or
complex programs. These programs must have a .GCD extension.
The ProtoTRAK KMX will also allow you to bring in a G-Code program and automatically
convert it into the KMX programming format. This is useful if you want the simplicity of
editing in the KMX format instead of editing G-Codes. It is not useful for large complex
G-Code programs. These programs must have a .CAM extension.
Both .GCD and .CAM programs will only operate with a limited set of G-Codes and M-
Codes. These are listed below.
