Stroke width i use is .002". I usually never play with this after I set it. I do spot check it once in a while or if I am playing around. I then always revert back to .002"

TJ - I tried this again with the line width set to zero and working in Outline mode. Now when I save as dxf all the dimensions match up.
So I think the line width setting was the one that was throwing me off. For most general plasma cut parts these small discrepancies may not matter - as the plasma can only cut so close. I just wanted to find out why the exported dxf was different than the drawing in Inkscape.

I have on occasion cut parts with my table and maintained accuracy to within several thousandths of the specified dimensions on the drawing/dxf. In the example below, this was more of a test to find out how accurately the SheetCam Scanything auto tracing program with digital camera could trace an actual part and create an accurate dxf file from the trace.
I drew the part to be exactly 4.750" OD with a center hole of 0.750" ID. Then I cut and measured the cut part and it was pretty close. Then I used the Scanything auto tracer setup to scan the OD of the cut part and convert to dxf and opened with Design Edge. I was very impressed at how closely the trace matched up the actual part. Perhaps not too practical for most plasma cut applications, but I just wanted to see how well the auto tracer worked.
