Here is a picture of my first try to engrave a dog tag which I bought from a Chinese shop. I thought it should be silver after the engraving process, but it came out gold - which looks even better :-)
I've used the default setting for aluminium.
What's the base material? Aluminium with some kind of coating?
Oh, and could you share the supplier?
The supplier was from aliexpress:
I've also ordered the mixed color set but wasn't able to test them so far.
I guess there is no choice of color for engraving aluminum because you need full power for that - no matter which color.
I've experienced the same with a blue dog tag. In my opinion it's because Mr. Beam uses a blue laser. which makes it not possible to engrave blue and green eloxed aluminum.
I will try a red one soon.
By the way, I've made a new black with two rounds of engraving, which looks better in the end. I will attach a picture later.
I have testet the colors green, blue, black - no result - only red - but I do not think it's very good and nice - I am disappointed with this laser - no good results and takes a long time
@G.D.: Use the advanced settings. There is a "line" option (don't know exactly the name, because I'm not at home) in the engraving section . The standard setting is 0,15mm -> change it to 0,1! The result is better, but needs much more time!
Sometimes I also make two rounds of engraving. Which needs incredibly much more time ;-)
The Setting is "Line distance"
Of course, this just helps with the "rastered" images, but not for the colors you are able to engrave!
how are the laser settings
