Im still getting the hang of things. I have 2d experience so thats the only thing ive done so far. I would love to learn how to do 3d with this xxl

Nice work John - Hows the learning curve been? Any stumbles yet? How long did that pocket for the pistol take to route?

Ditto on the 3D - I think the cad part of 3D will be the tricky part for me…

For 3D one needs to work up a 3D model, then use a 3D CAM program to develop toolpaths.

Thus far, I’ve used OpenSCAD for 3D CAD, and either pyCAM (free/opensource) or MeshCAM (bundled with my Nomad) for 3D CAM, and this has suited my (mostly mechanical) design needs.

See https://www.shapeoko.com/wiki/index.php/CAD#3D and https://www.shapeoko.com/wiki/index.php/CAM#3D and https://www.shapeoko.com/wiki/index.php/Commercial_Software#3D_CAD

You can use a careful bit of V carving, and use a ball-nosed endmill to get some contouring which can provide needed 3D features for some projects.

Example of using OpenSCAD: https://www.shapeoko.com/forum/viewtopic.php?t=1756

which when cut resulted in:

I took a picture with my phone and traced the outline with the pen tool on adobe illustrator. It was under 10 min.

I want to put a book around the box and make it like a hide a glock

Which would be a good cad program to make my 2d art into 3d looking? A skull for example. If i wanted to bring out the bones and teeth or something. Is that what you meant with the ball mill, Will?

My suggestion on V carving and ball-nosed endmill is to use Carbide Create and add the features there — using a ball-nosed to add a rounded bottom to a pocket is shown in: https://www.shapeoko.com/wiki/index.php/Carbide_Create_Photo_Tracing

These preview pretty well in Carbide Create, so you can experiment in the program to get stuff right.

I will give it a try, thanks!
Is there a certain way that v carving is intended to be used with carbide 3d? I tried it a couple of times but it seems like there must be a better way yhan what i tried. Luckily i have a borrowed planer so i was able to start over

V carving in Carbide Create ought to be straight-forward — if you’re not getting the expected results, please post the file and we’ll try to look into it.


(John Nicolosi) #10

Maybe i communicated that wrong. It carves fine, and the function works fine, i guess i am not sure of what a v carved job is suppposed to look like. Like what kind of work does it accent best or maybe whats the application for it… Im a total noob so chances are i ask questions without doing much research before asking… Sorry.

Well, we have a video tutorial at: http://docs.carbide3d.com/assembly/carbidecreate/video-tutorials/#v-carving

and some relevant posts here:
