    I would consider the photocopy and graphic pen as pre-processing, or image enhancements. But the conversion to diffusion dither, if done correctly, is the final step and will let you engrave exactly...

    Before you save your image from Photoshop, go to Image > Image Resize. Uncheck the "Resample" checkbox and then change the dpi to 300. Now save it. This won't change the number of pixels of the...

    Next time clean the image up a bit more to get rid of a lot of the noise/random pixels in the large open areas. Then in Photoshop convert the image to "Bitmap" mode (1 bit). Use "Diffusion Dither" in...

    Perhaps blast through the paint down to the metal underneath and then color fill with a contrasting paint color?

    Yeah, my understanding is that material is not for use with a laser. If you want a black mark on clear aluminum, use CerMark. If you want a grayish white mark on black or colored anodized aluminum...

    It does sound like you have a bit more control over 3D mode than with an Epilog engraver. I have done a lot of 3D laser engraving, and have used Photoshop and Corel to adjust the shades of gray to...

    I've never done it. All I know is what I've read. That it is applied to freshly cut mechanical engraving to darken the raw metal.

    3D engraving can give a decent photo, but I would expect it to be better on materials like wood that change color with power levels (higher the power, the darker the wood gets). It just doesn't...

    Technically, engraving any kind of plastic puts out poisonous fumes. People in industrial parks or the countryside that vent directly outside are just relying on the fact that the air dissipates and...

    The time it takes is going to be based on the speed and dpi settings you use. I'm surprised to hear you using 3D mode with stone. It's meant for softer materials like wood, where you can get a...

    I notice on Finch feeder pictures I see on the web that a lot of them use some bright yellow on them to attract the birds from a distance.

    A grouped object is a set of individual, separate objects that are treated as a group. But they are still separate objects, so each can have it's own fill and outline color.

    No idea if this is it, but in Corel make sure that you don't have layers turn off that are still set to print (look in the object manager palette).

    It looks like the two wires are different length, and the connectors they plug into are in different positions. I would mount the laser and see where the wires run naturally. It may be that the two...

    The 20,000, 30,000, or 50,000 hour figures thrown around have very little to do with how long a tube is going to last in your laser engraver.

    Those numbers are put out by tube manufacturers, not...
