long time lurker. finally have something I need to ask the more experienced users.
I own a 60watt hurricane laser-co2 one. acrylic and such is no problem for me. I have been asked by someone to do a photo on black granite. I went down to HD and picked up a pc of black granite 12" x 12" to do some trials on.
Checked the recommended settings and such. I am using photoshop to edit the photo. and then importing into laser cut.
speed of 200 power of 65, scan gap of .05 roughly 500dpi.
No matter what combinations I try, I really don't get anything except a blob of etched granite. All it looks like I am doing is exposing more of the grain.
What am I doing wrong? do I need a different editing software? scan gap too much?
Any help would be appreciated.
