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...
As a reference to see what it looks like, go half way down the following page and look for the black plates that say "Javier ECV" and "Habanero D". The caption says they are BowlBall font.

Make sure you get an adjustable regulator. 125 psi is going to be too much to feed in directly.
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.
I also notice a lot of them using what seems like a thin...
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.
When you "combine"...
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).
Also, make sure there is nothing that is...
There's a picture here you can test with:

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...
Actually Darren, the "PPI" he was talking about was not "Pixels Per Inch", which is what you are talking about. He's talking about "Pulses Per Inch" also known as "Frequency" in Epilog laser drivers....
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...
Browse through this forum and you'll find a lot of pictures of photos on wood, stone, etc...
His affiliation is that he owns A4dable Woodworking.
Not true. You are thinking about the "Normal" multi-purpose dry chemical fire extinguishers like you would buy at Home Depot. Those leave a coating that is not only hard to remove, but corrodes metal...
Mike, it wasn't quite spelled out in your post, but I gather that what you are saying is that when you raster the image, you are not going all the way through the wood. So you are left with a single...
LOL...
So, how about telling us a bit more about it. You know there's a lot of us sitting on the edge of our chairs waiting for more details so we can give it a shot.
I believe that the Laserbits ones are actually made for them by Chewbarka. They cost more, but you can buy them one at a time. Chewarka doesn't sell one at a time, though he's pretty good about...
