Frage Machining G10 with STEPCRAFT-2/D.420

Dear friends,

I want to buy STEPCRAFT-2/D.420 for a small scale production of hobby parts made from different composite materials. Mostly G10, Micarta and other plastic parts. Maybe some Aluminum or Titanium.

Few questions i have are:

1. Which software is best for 3d milling of materials, like knife handles and such.
2. Can i machine G10 under water?
3. Is this a good machine for those purposes?

Thanks a lot in advance.
