If all you need to do is profiling, then the free version of Autodesk ArtCAM should be all that you need: http://www.artcam.com/free/download/index.asp
Otherwise you should be able to complete the job using the free 30-day trial version of Autodesk ArtCAM Standard: http://trial2.autodesk.com/NET18SWDLD/2018/ARTCS/4489FD30-345A-4589-A593-9DD157E50426/SFX/ArtCAM_Standard_2018_ML_Win_64bit_dlm.sfx.exe
