What's up Creeker's? Long time no see.

I am working on the finishing touches on my DIY CNC machine. However, I am having some bugs in the software that I cannot figure out. As you can see in the attached screenshot of Mach3, I have a gcode file that I created with Fusion 360. I did the modeling in SAE units, but the post processes apparently default to Metric. It seems that Mach3 cannot detect that the gcode is metric even though there is a G21 code in there. When I start the machine, the spindle drops 6 inches and tries to go to X-216.812 Y35.293 in SAE units. Can someone tell me what is going on here?
