downloaded the 1.0.3 version of sheetcam to my linux box which has wine installed.
running the sheetcam .exe file seems to be able to handle it just fine, no problems this far, but I've only tried a very small program.
After saving the post processor file as a .tap, I had to edit somethings out in a text editor and then saved as an .nc file, which EMC is able to read and understand.
For those running linux, this may be another alternative to the lack of CAM out software.
