The V-Carve will likely be your first CNC created file. The software does a great deal of the work and creates beautiful carves from fairly complicated designs. Once your design is in vector form, you are ready to create a V-Carve toolpath. It is important to understand what the software is doing for you and how it decides the depths of cut that were made. In the simplest mathematical terms:
The depth of cut is a function of the distance between vectors and angle of chosen V-Bit.
Lets break that down a bit…
This design is what I am bringing into aspire. This could be a font, design, scan, shapes, etc.
This drawing is trying to depict the distance between vectors. You can see that the larger parts of the “K” have larger amounts of red. The center of the K has to also meet up all distances between the “K”
Imagine the “K” design on its side. The larger parts of the K design will get deeper carves. The thinner parts of the K will get shallower carves. This drawing depicts two parts of the “K” and also shows what happens when you choose different bits. Generally we will always use a 60 degree bit, but there are 90 degree bits, 30 degree bits, etc.

Here is what happens when you try to carve too thick.
If you override the thickness, this is what would happen to your wood.
One solution for this is to find thicker wood. For this example that is what I did. You could make the vectors smaller as well.
This is the same file, but I changed it to a 90 degree bit. It is a minor difference, but it also carves shallower.
Another solution is to add designs to the middle of your vectors. This makes the distance between vectors smaller
