Lagun HD V-2/Crusader II CNC

Vertical Knee Mill

I am purchasing this machine and need to do free form machining from solidworks models for mold cavities. has any one upgraded this machine, do i even need to?? i am an engineer and was a toolmaked for many years and took smartcam many years ago.. where to start can this controller do this type of machining? do i need a drip feed? what is the most inexpensive cam software that will take solidworks models?

thank's for any help or guidence...
