Thanks Jay...... ( Happy New Year !! )
As with the Vectric family of programs, the process could not be easier, as they really walk you through the process.
Looking at the attached, the "full_shell" is the file from my Roland PICZA, which is a bit rough, but provided the design,
from the end of a small sea shell, about 3/4" in dia.
I knew I was going to use 3/4" MDF, so I scaled the "Z" to fit the heigth.
In "slice_setup", I set the material to my 3/4" size, and 'checked' the box, telling the program to use the minimum size
material for each slice, as I knew my model was cone shaped.
In the "3-view", you can see the the result of this process, showing the first and sixth slice, of the seven used to produce
I used two bits, a 1/4", end mill, and a 1/8" ball nose, on each slice, so there were a few tool swaps before I got done, but
all worked out just great.
Oh yes, you can also see that, each 'slice' had tabs to hold the completed part.
I'm ready for the bigger task !!
