I’m new to CNC, considering a Nomad for flat inlay work on small boxes (it used to be guitar headstocks and fretboards). Suppose I cut the outlines of the stock (pearl, abalone, silver, ivory-like nut), pockets in the wood, then glue the inlays in place, flush with the surface on the box top.
Now I want to engrave fine lines in the inlay components, probably with a drag engraver. Is it possible to align the completed top so this can be done? Performing the scrimshaw-like engraving before gluing pieces in place typically results in some uneveness when the surface is finish sanded; engraving later is a much better solution for appearance.
I would somehow have to zero the machine on a point that probably wasn’t the zero for the outline cut. I would then also have to rotate the top to the proper angle that the inlay was originally cut. Maybe repeat this process since rotating would probably move the origin somewhat.
I guess this would have to be done with Carbide Motion which, not having a machine yet, is yet a mystery as to its utility. I suspect I would need good reference points on the inlay, with probably two on the same axis, with accurate distances inbetween? Possible?
Edit: I think I would need this: Can Carbide motion move the spindle to a particular area and then have that area assigned a particular non-zero value for a machining reference?
