CAM for new 5 axis machine

HI
I am looking for a free or affordable CAM program for an xyzbc router that the fairies have made in my workshop. I have tried the cnc toolkit but can't seem to get it to work. Can anyone suggest a program I can use. I want to try and machine wooden busts from stl files.
Thanks

You may have a long and fruitless search.Can you post a diagram of your machine?There might be a faint chance if you have a 3 axis machine with the enhancement of a rotary table on a tilting base.
