Would you mind posting a link to the info Bill?
The thread on the Vectric forum I found most useful is
this one.
I copied and printed the following from it:
Stacked Text Process
1. Create 2 Layers (Upper and Lower). Leave both visible.
2. Create your upper text on the upper layer. Create another vector as a border, one that will be large enough to encompass both the upper and lower text. At this point convert the text to curves. You can now node edit the text to eliminate loops/artifacts, and 'weld' the touching letters together (if required). Group the entire text (but not the border), and hide the upper layer.
3. Create bottom text on the lower layer. Convert to curves, edit and group the entire bottom text as you did for the upper text.
4. Show the upper layer, then right click on the upper text vectors and border and select the copy to lower Layer option. This will send a copy to your bottom layer for welding. Once again hide the upper layer.
5. Now select both grouped words on the lower layer (but not the border), and click the "Weld Selected Vectors" button (right below the mouse pointer button on the left side under "Edit Objects").
6. Success! Now continue on to machining.
7. Show the upper layer (hide the lower) and select the upper grouped text and the border. Create a V-carve toolpath. I usually cut the first layer to a depth of 0.05 with a 60º bit (tip ground down slightly (0.037) to pocket cleanly between the letters), and a 1/4" end mill for the large area clearance.
8. Now show the lower layer (hide the upper layer) select your welded vectors and the border. Create a V-carve toolpath to a flat depth of 0.1 with the same bits.
