3D Cutout

Postby GervRich » Sun Jun 10, 2018 8:02 pm

Hello All,

I am very green to the CNC world and only been using VCP for the last 2 weeks. My questions is how can I take a eagle 3D model that I have and make it raised on the material instead of having it below the material. Any help would be greatly appreciated.

Create a pocket that is the same depth as your eagle model is thick.

Place the eagle model in the pocket and it will be raised above the surrounding pocket floor.

Made a 3.5 minute video of the process for you. here is the link:

(Note: I mistakenly narrated that I used a .125" BN for the pocket. Actually, I had a .125" EM for the pocket and a .125" BN for the Finish Pass for this quick-n-dirty example.)

Thank You so much. This amazes me how willing and helpful people are on here. Thank You for taking the time to make a video.

If you don't mind me asking, what is the boundary offset and why would that be adjusted? Would it be adjusted based of the bit that i am using.

Thanks

You are very welcome.

The bit Offset of 0.07" is slightly more than the radius of the 0.125" BN carving Bit. If that Offset wasn't specified, the center of the bit would stop at the vector boundary, thus not fully carving the edges of the model. It's common practice to specify a tad more than the bit radius for "insurance".

Many of the tutorial videos mention this, albeit sometimes not emphasized except in a few of them. Since you are new to the software, watching the tutorials will be helpful I'm sure. Try to watch at least two a day (or more, if you have time and don't get brain freeze too easily!).

Hey Mike,

Not sure if this will get back to you but I have been having a little issue with the 3d image. I do everything like your video to a T. For The project I am trying to do is a 3d model of a american flag with a eagle. I got this from design and make. I am doing it on a small 6x6 and i am using a 1/8 BN. The issue I am having is when i go to do the finishing pass on the imagine it drives the BN all the way to the bottom of the wood.

Now how i setup is the XY is in the middle of the board and this is because i am using a touch plate for virtual zeroing. I virtual zero to start the job and once the pocketing is done i do the same for the finish pass. Now I save two separate files on my USB. One being the pocket cut and the second being the finish cut.

I'm sorry if i'm not making any sense but I cant figure out why the BN is plunging all the way to the bottom on the finish pass. The Pocket pass works just fine.

Thanks
Ric

Would it be possible for you to post a copy of the .crv file here on the forum? By reviewing your file we here can solve your mystery problem without having to go through a bunch of wild guesses!

There is a size limit on the files that be uploaded directly to the forum. Sometimes you can ZIP the file to get it under the 3MB limit.

Otherwise you can upload it to a Google Drive, or a site like dropbox, and then just post the link to the large file.
