Ok this one took a while to cut (nearly 5 hours).
So I looked at the submissions, and noticed a distinct lack of Carbide3D logos in the designs.
Or hexagons.
So I set out to solve that.
Picture to show the modeled round-upwards toolpaths
But I also wanted to show the STL2PNG tool I’ve been building…
(https://fenrus75.github.io/FenrusCNCtools/javascript/stl2png.html)
…but I didn’t want to do the traditional horse or eagle in a bowl. Had to be CNC thing…
On thingiverse I found an STL model of a simple spindle: https://www.thingiverse.com/thing:3790264
I had to add 2 features to STL2PNG to be able to use this model, so that took some time, but I’m happy with the result:
even the tool nut came out quite nice.
And then @Julien asked in How would you mill this? how to do 3D carving in CCPro with a round design… so obviously I had to have a spontaneous volcano (Mt St Helens) in 3 hexagons:
Long cutting time short, the overall came out ok, had some warping issues with the stock near the end:
Now to the digital side:
I used a 1/4" downcut endmill for the major roughing, then a 1/8" inch downcut to make the points in the hexagons relatively sharp (this takes forever) and to do the roughing for the 3D models.
Then I used a 2mm endmill to refine the text, and a 1mm tapered ballnose endmill to do all the 3D carving.
While no animals were harmed in the creation of this, Carbide Create PRO did not fare so well. I’m at 3 bugs at this point (will need to file tickets with support)
- The left top and left bottom hexagons are not getting cut out… but they should be (you can see this in the file)
- If you delete a layer in the model view with my file, instead of 1, TWO layers get deleted
- When doing a 3D roughing pass within a box, the center of the endmill stays in this box, but the radius is not taken into account so the cut veers outside of the box you gave it…
