No need for a video... I understand now. Thanks for explaining.

I still have many questions about your process and finishing technique.
I have so many that i'm struggling to get them straight.
I guess it starts with the machine settings.
While I understand the cut depth, I don't understand the stepover.
Its called out as and percentage.
But a percentage of what???
Also what is your specific process for the finishing?
After I do a carve, I seal it, then paint it, and when the paint dries I sand it to make the picture appear.
But mine don't even come close to what you're producing.

The finishing process I described in a previous post, "New process 1st attempt" a while back. When I go back and re-read it it kind of rambles on :oops: but it does detail the fill composition pretty well.

As for the machine settings here are the settings I used for the picture of my grandchildren.

The percentage is a function of the tool's cutting diameter. In this case .25 mm radius = 0.020" diameter X 20% = 0.004 line spacing. The slider does not go below 100% so you must type in what you want if you want less than 100%. With these setting you end up with a kind of gray scale bas relief instead of a V-carve. By using these same settings and checking the "Invert light / dark areas" box you get a lithophane if done on white(ish) solid surface. I hope this helps.

I'm currently out of state and won't be back in my shop until next week.
But if you don't mind, I would love to pick you brain further.
Your work is fantastic.

What version of V carve do you have??
You seem to have much more control / information than I have.

I think you are confused.
He is showing the parameters and settings in Photo VCarve and not VCarve Pro.

Jozua is correct in that I am using the stand alone version of Photo VCarve. I am glad that you posted a screen shot of the VCarve 10 version of the Photo VCarve tool set up screen though. To me, the most important feature you are missing is the line spacing calculation. However it is kind of cool that you can project your work onto a 3D model. I have never tried to do that when importing a Photo VCarve file into VCarve desk top but I am not sure it can be done.

One feature the V C 10 version has is the "Start Depth" setting. That would be a nice upgrade for the stand alone version.

I am not sure what the contrast slider accomplishes either. I sometimes set it as kind of a feel good thing but I have never really had anything much improved by using it; neither have I had it cause me any problems with the final product either.

I still believe that if you create a V bit in your tool data base with an included side angle equal to a small radius tapered ball end mill's you could trick the VCarve 10 version of Photo VCarve into making lithophanes and photo reliefs similar to what I am doing with the stand alone version. I'd try a 15-20% line spacing with a .25 mm rtbem and see how it goes.

I didn't realize that there is a difference in the programs.
I kinda thought that photo V carve is ,,well,, photo V carve. (why would it be different?)
However, I must say that after studying the tutorials, and trying different suggestions from the forum, I am still not getting good results.
I find it interesting that the tutorials show great results. (in the simulation)
I show great results in the simulation also, but when it actually cuts, it's nothing but expensive firewood.
So now I'm wondering if anyone on here has actually used the Desktop V10 version and what their results are.
