What exactly do you need to know? The only connection between the two is the post processor. I don't see a UCCNC post included, but the mach3 post will probably work. You might want to ask Vectric support if they have a UCCNC post.Now I need training material for compatibility with UCCNC and Vcarve Desktop
If you need Vectric help, then you need to start watching all the tutorial videos that they have.
Do you have any specific questions?
