There is a standard Biesse postp in VCarve Pro that appears in the pull-down list on the Save Toolpaths form as - Biesse Rover Arcs (mm) (*.*).
We certainly have customers running Biesse routers with this postp but I know some of the older controllers may not work with this. You can test the output using the Free Trial version or send a note to - support at vectric dot com - and we'll see what can be done.
I hope this helps,
