Rounded Corners

Frist, I want to thank everyone on this forum for the all the help I have gotten to help me get started with Linuxcnc. 
I got the machine running and cut so test parts and everything was fine, so I set up to cut my first parts on the machine and now everything I load to Linuxcnc  it rounds the corners. I was using G64 P0.001 and was working. But when I loaded the inlay Gcode It rounded the corners and everything else I put in. I have tried G64, G64P0.001, G64 P0.001, G61, G61.1, G90, and get the same results. I have no idea what happend.
I can't use it if I can't fix this.
Here are some pictures and the Gcode.
Hope someone can help with this It has been a very long road for me with this project.
Thanks

This ^^^

Tommy is 100% right: It is the g-code.  Just put your file here to see: ncviewer.com/

Did you actually see the rounded corners in the final "cut" material?

This looks a lot like ordinary "pivot around the corner" that most g-code generators use.

It looks rounded, but the end result will be perfectly square corners.
