I have to do some outdoor trail maps so I carving them on King Color Core. All their "tips" are for folks using big industrial CNC machines. Just wondering if anybody has experience doing this with Vcarve / desktop CNC machine. For example in their video http://www.kingplastic.com/video/video-route-engrave-king-colorcore/
they are showing flat bottom letters carved with a very small v engraving bit. Never done this is Varve. The letters were always actual V or raised letters in a pocket. This is almost like every letter is a pocket.
(the rationale is this is layered product where you machine away the top layer revealing a different color "core")
