Cody,
As always, experiment with it a bit, but I recommend telling PhotoGrav the dot size is at least 50% larger than it really is. On your TT (and the Mini18) the dot size is between .0055 -.006" so tell it .008 or .009. The Mini24 and all larger/newer Epilog's spot size is just below .004" (with the new Radiance Optics) so I use .006 or .007 for "kissing" marble and a little more if I'm hitting marble hard or doing granite.
HTH,
Edited missed question: Your TT is faster than the Mini; I might recommend dropping your speed to 65-70% as a conservative starting place ---- as we all know, we can go over it again if the properties of the marble (or granite) dictate, but espcially on marble if you "wash it out," you throw it away.

Roy,
I will definitely try that.
What about the dpi settings...would you use 200 dpi on marble (will it have the same effect)?

Cody,
Again, you'll hear many who do more engraving than I, say to use 500/600dpi, but like the effect and the speed of 200dpi.

Thanks again, Roy.
I'll make it a point this next week to play with those settings.
By the way, we'll be exhibiting at the Hopkins County Fall Festival this next Friday and Saturday. If you happen to find yourself on the east side of the metroplex either of those days, stop by the Civic Center and visit with us.
As you know, we'll be taking the Epilog out there this time to do on-the-spot engraving. This is our first time to do something like this, so we're VERY excited!

Cody,
Take notes and give us a play-by-play observation of your experience. We will all be waiting with baited breath.
