Reminds me of "cultured marble", which I thought was a funny way to try and hide the fact that it's just plastic :P
So no ballnose on the V-bits, you're just using a relatively small stepover? Is there any kind of manual cleanup after cutting - sanding or anything? They look really good, and detailed!

Hi Charlie,
Yes just a 30 or 60 deg v-bit. V-bit has is a true v-bit - no round over on the tip. On the penguins I used a 60 deg bit. On the portrait one I used a 30 deg bit as it had some cuts that had close to vertical sides. The 30 deg bit can go deeper when the cut has close to a vertical side. Yes very small stopover (0.0075 inches). The small step over means that even with the deepest cuts (0.20 inches) the bit is not overloaded as it is only taking off 0.0075 inches of material.
The only cleanup I do is to blow off the dust when I take it off the CNC.
I spend more time building the frame and LED light panel (3/8 acrylic surrounded by LED lights) that goes behind the carved panel. For a switch I use an RF remote control in the base.
In PixelCNC the canvas is at 200 ppi - maybe helps with the detail of the carving?? Still playing with PixelCNC settings.
