Need Help Thinking Through 3D Carving

[iantyndall]

All,

I am having some trouble applying my understanding of 3D carving with Carbide Create Pro.
I am trying to create a carving in a 0.75" board that is has a cove, but a embossed like image in the cove, like this:

Here are my steps:

1. Setup project with 0.75" stock thickness
2. create a rectangle for the base
3. create a circle for the cove
4. On the model screen, create 1st model with “Add 0.75” for the base
5. create 2nd model with a 4 degree angle for the cove and “subtract”
6. create 3rd model from PNG and “Add” it back in with a height of 0.2

This is the model view I get which is pretty good but not centered:

When I add toolpaths it gets really wonky:

I am clicking on the circle to create the 3D Roughing Pass, and then adding in the 3D Finish Toolpath.

I am clearly doing something wrong, but I can’t seem to figure it out. Any help is greatly appreciated!

Post the .c2d file as well as the source files?

this is kind of similar to something I did before with CC pro:

I did this as one layer in CC (in gimp I did the “bowl” mixed with, in my case, the STL of the spindle turning it into one single image)

[fenrus (Arjan van de Ven)]

one key thing to decide is if you want the bug to “follow” the hollow area, or if it should just come out of it “flat”… how you approach this depends on the answer to that question

bee-example.c2d (1.7 MB)

Those are my files.

I see what Fenrus did, and that seems like the best way to center the bee on the cove.

Thank you for this example. I was going for the bee coming out of the hollow area, but it ended up looking like it was following it because I couldn’t precisely align the bee image.

the magic in gimp is to make 2 layers, and make the upper layer have the “max” operation to blend the two layers…

[iantyndall]

Is there a setting to determine the depth of the colors in Gimp or on the PNG file?

[fenrus (Arjan van de Ven)]

ok so the whole range from black to white is the height you set in CC

in gimp, in the colors menu there is a “Levels” submenu that allows you to scale the range of your active layer to exact values… with that you can control the Z range of each of your layers
