Thank you for your comments. There are a number of factors to get the results we are getting, first is the quality of the stone you are engraving, the closer the crystalline structure the better the etching, also some of this work you see is done in more than one file. On big images 2 foot or better I may do the face and skin of a person in a separate file (lower power setting), this means running the laser more than once over the stone your putting the image on. If the crystalline structure of the granite is tight (very small) you will need less power. I run my 60 watt co2 at 700 IMP with only 1.5 watt on the power on an average piece of stone. Very little power is required at slow speed of a big laser table. Second is to use corel or photograv to the max, I mean you have to understand the Photograv gray scale and line enhancement like the back of your hand to get perfect results. We are in the stone business, so I have been lucky to have many different products to work with and have experimented with them as it would be very costly for someone to purchase this product and experiment with it. On a new piece of stone the first thing to do is start out at a lowest power setting then increase to get the results you want. Do you still have your laser? I would be happy to show you if your ever in the area.  |
