CNC metal machinists (for Stax amp cases) unite?

Diamond drag engraving is surprisingly fun and easy.

I decided to buy a spring loaded diamond drag engraver and do some experimentation on feeds, cutting depth, stepover etc.

I ended up. 90 degree drag bit. tip flat estimated at 0.128mm, 0.1mm step over, fill crosshatch at 0 degree, 700mm/min feed speed.

Far better results than using a V bit, much less sensitive to the material not being totally flat and far far faster.

Nice James. 

Now change the face from Times to Arial and it will look even better.
