Photo Engraving Test Image
Here is a test image that will help new users of PicLaser Lite to get started engraving photos. I chose this GrayScale photo because visually will give you a better idea how to judge the shading when laser engraving. Our PicEngrave Pro 5 program has a GrayScale preview for color images in the image editor and in the program itself.
PicLaser Lite does not have this option, but our PicEdit Lite program does for use with PicLaser Lite. I re-sized this image in PicEdit Lite for the size of Poplar I have. The only editing I did was sharpen the image to 10. The original image was 72DPI and PicEdit Lite saved it at 100DPI after editing. We recommend a minimum of 100DPI resolution when using our image to gcode programs.
Here is the original image I downloaded from Wikipedia Commons. http://upload.wikimedia.org/wikipedia/commons/2/20/Lynne_Roberts-Roy_Rogers_in_Billy_the_Kid_Returns.jpg
Here is a download of the edited image to generate the Gcode yourself with PicLaser Lite. If you duplicate my settings, the engraving size will be 6.678" X 5.25" (169.62mm X 133.35mm)http://www.picengrave.com/downloads/darklylabs/Roy Rogers.bmp
Here are two screenshots of the PicLaser Lite settings to use for generating the gcode. One is for inches and the other for Metric.
With the size of the engraved image, don't expect the dots on Lynne Roberts Dress to show clearly in the engraving. They are smaller then the size of the laser beam's focal point, so they will just be blended into the engraving. The larger your engraving is, more fine detail will be visible.
Here are two Gcodes to run on your EmBlaser I generated from this image if you prefer to take that as your first step. Remember X&Y zero is at the lower left corner and will engrave up and to the right from there.

If your engraving comes out too light, lower your feedrate. If it comes out too dark, increase your feedrate. If you want to edit the gcode to change the feedrate, our PDF explains how to do this.http://www.picengrave.com/Pic Programs Page/PDF Files/misc/Understanding Gcode.pdf
