    Granite from Lowes

    I am sure some of you have used granite tiles from Lowes.
    My question is what are your settings for this.
    I have an Epilog 45 watt mini.
    Thanks.

    Ross,

    my settings for my mini 45 are
    600 dpi
    75 speed
    40 power

    I use one tile for testing. I crop the face around the eyes of a photo into a 1 inch square and make sure it comes out good.

    I run granite at 600 dpi for photos, and 300 for text @ 80-97 sp and 100 power on my EpiogTT which is somewhere between 35 and 45 watts. The speed varies with the granite source..
    Epilog 24TT(somewhere between 35-45 watts), CorelX4, Photograv(the old one, it works!), HotStamping, Pantograph, Vulcanizer, PolymerPlatemaker, Sandblasting Cabinet, and a 30 year collection of Assorted 'Junque'

    Every time you make a typo, the errorists win

    I Have to think outside the box.. I don't fit in it anymore


    Experience is a wonderful thing.
    It enables you to recognize a mistake when you make it again.

    Is this the 'absolute black' Chinese stuff? (I get mine from Home Depot, but I suspect they have similar stuff at Lowes.)

    Those settings sound insanely high: I normally use 100% speed and 25% power on a 25W ULS machine. I started with the "recommended" setting (which I suspect is actually for marble, 60% speed, 100% power IIRC), but a bunch of experimenting convinced me that "less is more" where power is concerned: higher power just seems to blow out the detail on photos.
    Yoga class makes me feel like a total stud, mostly because I'm about as flexible as a 2x4.
    "Design"? Possibly. "Intelligent"? Sure doesn't look like it from this angle.

    I'm with Lee on this. I just did one on a 60 watt Universal, 40 speed, 9 power, 300 ppi.

    Thank you guys.
    I had tried one before posting this at the recommended setting for marble, which was power 100 and speed 20. This turned out way to washed out to even tell what the picture was.
    I will try Mark's setting and go from there since he has a 45 watt also.
    THANKS EVERYONE!

    100% with Lee. The laser fractures a chip of granite, and marble for that matter. However, the granite chip is generally much larger than marble. If you fire too close to the last fire then there will be little or no contrast because the chips overlap. Also, the more power you are pushing the larger the chip will be. So back off the dpi and the power. A slow speed will also give more detail.

    With that said I never run granite over 200 dpi and often run large pieces at 100 dpi. Marble is run at 300 to 400 dpi. Because of the difference in laser power I'm not sure you can use anyone else's except for a starting point.

    By the way, I have used Lowes absolute black granite for about a year now. Can't hardly beat it for less than $8 a square foot.

    (cough) I've never paid more than $6 each at HD...then again I haven't bought any since I loaded up the last time it was on sale for $4.

    All I have locally is Lowe's. I ordered 2 cases, 10 per case. With shipping it was $79.60 per case. Oh well, maybe I'll get to Home Depot soon and check them out. When you live in Corbin, KY, you just do what you can.

    Key word there being "shipping": these things weigh about 6lbs each.
