Help with V Carve boundaries and settings

Post by tjop92 »

Hello,

I am trying to figure out how to make a carving using the v carve option but haven't been able to learn how to set up boundaries. I attached what I am trying to carve. Basically the red areas I an trying to carve out with a v bit, while leaving the surrounding non red ares uncarved. How should I go about doing this? Any help or direction is greatly appreciated! :)

Have you watched any of the tutorials on how v carving works?

Hello,

Yes, I did watch through them. I don't recall one going over this, but I did it over a few months. If there is one that addresses it could you let me know which one and I will happily watch it. :) Thanks for your help. :)

Well, the first step would be make sure they're vectors importable into Aspire. The second step would be to actually import them into Aspire. From then on it should be a snap to do this.

Simply put, you select the vectors you want to carve in between.

Terminology here may be playing a part, the vcarve toolpath is quite specific on what it does & from looking at the picture you have attached I don't think that is what you are trying to do.
Are you just trying to clear out where the red markings are & if so is there a particular reason why you want to just machine those areas ?

Sorry but I am not 100% clear on what you are trying to achieve & why :lol:

As I engraved it some weeks ago on PMMA, giving v-carving a try was very quick (it's reverted because I engraved the back of the PMMA).

As Martin wrote, I'm not sure V-Carving is what you want.

Ted has summed up V-carve principle in a few words.

Search the forum for more explanations. I remember somebody posted a very good schematic diagram.

Here is the result with a pocket toolpath.

It's straightforward if you have clean vectors: closed and without overlaps.

Basically the red areas I an trying to carve out with a v bit, while leaving the surrounding non red ares uncarved.
If it is carving the wrong areas, select the outermost vector and offset it outward, so you have a new outer bounding vector (but keeping the original vector). Select all your vectors and V-carve. With that new outer vector added to your selection, your carve will reverse what is cut.

BTW, you probably need a cleaner original. Your vectors look a little crude.
