I have done this hundreds of times in the last several months and it works for me. I draw my projects in AutoCAD and save it as both a DWG (for a record) and a DXF (2007).
I am an Adobe Illustrator user and open up the DXF file, be sure to set the scale to 1:1 (important). I do my text and other things in Illustrator and then save it as both an AI and a SVG file. Easel has read 100% of my SVG's and carved them great. I am not an Inkscape user, but I don't see why the same process will not work with Inkscape. I just tried the same thing in Inkscape with excellent results.
I created a rectangle 2" wide and 3" long in AutoCad. I saved the drawing as a 2013 DXF file. I opened up Inkscape and set my drawing to 8 1/2 X 11 and inches as default. Next I imported the DXF, I tried several tomes as a scale of 1 and that did not work. I googled DXF into Inkscape and the answer was to change the scale factor in Inkscape Import to 25.4. Once I used the 25.4, it worked great. I then saved the drawing as an OPTIMIZED SVG. I opened up easel and it imported with no problem. I also verified the size and it was right on. It is possible to at least do the conversion from DXF to SVG with a free program. Those that do not have AutoCAD can opt for a free program called Draftsight. This works just like AutoCAD. This is a free program, but be aware, if you do not have any CAD skills, this program, as any CAD program can be unsetteling.
