Could anyone help with this 3D Carve?

[latenightdesigns (Tamara Marrero)]

Good morning all, can anyone help and walk me through the process of carving out the attached STL? I am basically putting the attached design on a tray, carving out the STL attached and then I will fill it with epoxy. The material thickness its going on is 1".

I have not messed around much with 3D carving much, but I have been trying to find videos to follow and every time I try to follow steps it doesn’t end up looking right on my end. When I do the tool paths I try to use different bits that I have but nothing ends up looking right.

Any help would be appreciated.

It won’t let me attached the STL File, so here is the download link. marijuana.zip - Google Drive

If you’re still stuck, upload your .c2d file and describe in what way the 3D preview isn’t appropriate to how you wish to cut things out.

Hi Will, thank you for the response. Here is the Carbide Create file I am working with right now. I am trying to start smaller and do an ashtray first. I have changed the tool for the 3d roughing and 3d finish from 60/90 angle bits to 1/16" so its smaller and get the details. But whatever I do, it still isn’t showing up correctly in the preview.

Update to current/supported v8:

Either re-create your 3D model by reimporting, or, convert per:

Is this what you’re after?

Assuming so, here show I would proceed:

Something I’ve figured out this last couple weeks is to use the 3D rough pass and the first finish pass for the field as well as the model. When you use a very fine stepover for that first finish pass the field is very uniform versus doing it as a separate pocketing operation.

You may want to adjust some of the parameters I’ve used. Say, make your base 0.50" high versus 0.75" so that your leaf lies deeper and can be covered with more epoxy. You would then adjust the rim and leaf height accordingly.

I didn’t include any bit recommendations, all my bits are specified in metric. Although I like my freedom, I avoid “freedom units”!

[latenightdesigns (Tamara Marrero)]

Thank you so much for the reply this helps a lot! Would you be willing to suggest bits for the tool paths? I’m newer to CNC so I am always open to suggestions.

[bpedit (Byrne Pedit)]

For the rough pass maybe between 2mm and 3 mm. You might decrease the DOC (depth of cut) a bit which will leave less material for the finish passes. Set Stock to Leave at 0.2 mm or so.

For the first finish I start by trying something close to 2 mm. Be sure to use a small stepover for a smooth field.

For the second finish pass, try a 0.8 mm or so. This one’s tricky because you need a bit long enough to clear the sides where the 3D meets the field. This is dependent on how much relief your leaf has relative to the field. All my carvings in this size range have a maximum relief of 4.0 mm. If you find you’re breaking bits here you can shrink the boundary of the leaf a bit so that the bit doesn’t travel all the way down to the field, this is where it is is most likely to break.

I’ll leave it to you to find appropriate bits in Imperial Units. 1.00" = 25.4 mm

Hope this works for you. I’m relatively new to 3D carving, still finding things out.
