In case you were wondering...

After a bunch of attempts, I've probably just re-created the wheel.
But, just in case you were wondering, it is possible to create Lithophanes using Vcarve Pro 10. I had already used Photo Vcarve to create a litho from a photograph of our daughter. I wanted to use the same picture and see if it could be done using Vcarve Pro 10. I did use Gimp to remove background distractions from the picture. All other procedures were done with VCP.
Here is the original picture:

Here are the lithos. I put them in the window on an overcast day, so they aren't as bright as I would have liked for this view,

YES! I thought it could be done in VC10. Can you share your setting?

Here's the recipe that I used:

Photo Vcarve toolpath in VCP
I used .125" translucent white Poly carbonate about 5"X 6"
Start depth 0
Max carve depth .11
Stepover retract .12
60V .25 dia bit
Tool setting: pass depth=.115, finish path step over=4%,clearance step over= 24%,Speed was high but producing chips without any welding, feed=200 ipm, plunge=40
Raster spacing 7% line angle 30 degrees
I used double sided interior carpet tape to hold the plastic to a 1 inch thick block. This kept the surface flat, since there was not much room for error.
Cutting time= 24 min. 43 sec.

The whole process was about the same as using Photo VCarve.

There were a whole lot of trials before this worked the way I hoped.

And...Don't forget to use the Picture Editor tool to invert the picture for a litho, and convert to grey scale.

Thats awesome Bob! Thank you for the tips! I really want to try this! May I ask where you got the .125" translucent white Poly carbonate?

A friend gave it to me...big help, huh?
Some have used solid surface material with success.
If you search this forum under lithophanes, or lithos, you will get more information about materials that work.
