I have a Ghost Gunner mill and started to play around with the engraving code this morning. Super easy to use.
The top lower was the 2nd one I did, was able to move the image around and size it bigger and only cut it at .1 mm deep
The bottom was the 1st time engraving, I cut it too deep at .8mm and doesn’t show the detail of the image, luckily it was done on a junk lower.
I used a 60 degree end mill bit, I’m thinking a cutter with a 20 or 30 degree will help with those fine detail images.
