Question for any and all. First off to explain, I'm trying my hand at converting a photo to a carving.
Question: How does one control the cut depth of the image in this situation. Some of the fine detail is only .010 deep or less, can hardly see anything and the max is only about .065.
No matter what I try in the tool path, like giving it a flat bottom cut depth. I ended up telling the project that the material was .032 more than it actually is. OSHA approved???

Cary can you post the picture so we can see what you are trying to do?

It really depends on what type of picture you have.

Are you using a V-carve toolpath or a profile toolpath? When using a v-carve tool path, the bit can only cut as deep as the outline vectors allow. It's like putting a funnel into the neck of a bottle. The v-shaped funnel can only go in so far before the funnel's sides make it wider than the opening. The vector outlines of your artwork are like the angled sides of the funnel, and the bit can only carve down until it hits the vectors. The only way to control the depth is to either make the vectors of your artwork wider or use a smaller angled bit like 45º or less.

To use a profile toolpath, your artwork will have to be single-line vectors and you can cut on the line to any depth you prefer.

Naa, no picture, I don't want to. lol
Using VCarve Pro 9. something.
The problem I'm having is lack of knowledge and skill in the program.
I have to tell myself, I'm a cnc newbe, remember > baby steps... But I want to do the cool stuff NOW!
No real help needed here I guess other than a knock upside the head as they say.

Is it like the first picture or the second picture?

The first picture is easy, the second picture would be a lot of work and may not be what you want to do.

Yeah, the second one. More like this, one of my family members. Best I could do using photoshop cs5 but when changin to vectors it really looks bad. Maybe too much detail in the image.

Actually Cary that is not too bad but I do see that most of it is very small vectors so you will have the shallow cuts unless you make the project larger.

You might try using photoshop cs5 again and fit the vectors a little looser and see what kind of results you get.

Nice looking dog by the way.

This is a quick vector fit in Aspire (same tools in VCarve). then edit by deleting one vector and offsetting two vectors, deleting the original two to get better definition around the nose. Still needs a little tweaking but that was something I expected. The design is 85 to 90% of most jobs.

Toolpath set for flat depth of 0.06 and highlighted with black.
