-Black 'Cermark' etching on a PowerMac G5 side panel.  This was done with standard Cermark settings:  100% power, speed set to the wattage of the laser which was 45 in this case.

+On a 45w Epilog Helix a setting of 100% power and 15% speed achieved the darkest and most uniform black using Cermark spray on the prushed aluminum side panel from a G5 tower.

-Examples of normal white etching and black Cermark etching on a MacBook Pro.  The white was etched at an earlier time and I didn't note the settings.  The black was done on an Epilog Helix 45 watt with standard Cermark settings:  100% power, speed set to the wattage of the laser which was 45 in this case.

+Sadly the wavelength from CO2 Lasers make it really difficult and almost impossible to engrave on polycarbonate. The only solution (so far) to engrave this material is to use a YAG/Fiber laser. A great example of this technology used on a white MacBook is on the following link to the Epilog’s website.

+====External Hard Drive====
+% power, 46% speed (75 Watt helix) works wonders on a Seagate Goflex hard drive.

+==== Titanium metal etching/marking ====
+Having just completed testing of both bare etching and Cermark marking, I was rather surprised with the results.  It appears that titanium will mark under just the power of the laser alone, and the color will vary according to the amount of energy utilized (in this case as a factor of power * speed).  Here is an image of etching titanium bare, and with Cermark:

+=====Glossy Tile Etching=====
+After giving this a shot, I found that a speed of 92 and a power of 80 works pretty dang well (I used a 75 watt helix so your milage may vary). Home made coasters!

+====== Lima Beans ======
+Using a 35W Epilog mini, 60% power 100% speed. The beans should be placed in some sort of soft holding bed both to even them out as well as to stop the air assist from moving them. We used lentils and eventually made a jig with cardstock to mass produce the beans.
