Just something I tried during the holiday - as opposed to 'inlay' this is 'onlay' or laser marquetry.
This example is rubbish really because it was produced by cutting two identical images from different veneers and then transposing the parts. It has no allowance for tool radius offset so I have filled the kerf just to see the end result.
By thickening the outline of the original .dxf I should be able to produce two toolpaths (one for cutting on the outside of the line and one for cutting on the inside of the line) then, if I get it right, the parts should fit exactly with no visible kerf.
A lot more experimenting before I get it right but it is an interesting technique and eminently suited to lasers.
Tweakie.
