I found a really nice grayscale image on the web that I would love to make a 3Dengraving on a box . the image is 16" x 7" with the fingers starting just beyond that all around and the front of the box also fits in the cutting area as well.
I started with 400 LPI and after a bit the GFUI just started laughing so I have been stepping down the LPI first with and then without the cutting out but I have not achieved a setting it will accept. It takes quite a while for each case and I was wondering if someone had worked out a formula.
