Copper

Hi trying a first attempt at engraveing copper sheet with my shark pro hd, any suggestions. As far as speed and what type of bit? Thanks

I have engraved brass plaques and used the v carve bits. I used the speeds and feeds that were set up in the tool library and they seem to work fine. I always slow the feed rate down and gradually increase it as needed. You may have to trial and error the depth of cut to suit.
