Hi
I've been doing some engravings in aluminium using a spare piece I has lying around.
I've used a V-bit 0,1mm tip, 45º. 0'05 machining depth in just one pass. Highest possible spindle RPM(about 20000), cutting feed: 75, plunge feed: 20 (mm/min)
In 3mm letters everything looks fine, but when doing 2'5mm or less, the holes inside the letters dissapear.
Also, I'm not sure if the tip was broken, the traces look much wider than I calculated (those tiny tips are hard to see clearly for me after some hours working).
Any suggestion is welcome
