Please Help - Need sample file ASAP

Hello:

I have a 3 axis CNC machine. Honestly I just never learned to use the software due to moving and medical problems. Have to
move again but this time into a small apartment. My CNC machine is all configured with Mach3. I have a guy coming over to
take a look at it but I need a simple file such as a square just to show him that the machine runs. I informed him that the machine
probably needs fine tuning but even when I run one of the sample files the machine sounds rough. Even though I've informed
him of this I'd like to run a program that shows the X, Y axis accepting commands from file. I can control each axis through Mach3
but I would really like to run a simple program for him.

If someone could point me in the direction of downloading a simple square pattern I would appreciate it greatly.

Thanks
David
