I've been having a lot of fun working on the new chinese laser. Much different than the US ones. One thing I've noticed is the Chinese laser has little lines in it in between each row, and/or where they overlap (in my limited testing). See my attached photo, this is what I was able to get it after some tweaking. If you look very closely you can see the little lines where each row of the beam meets. **NOTE: The built in camera of my phone smooths some of them out so they are harder to see in the photo than in person.** Using a 2" lens at 800 speed here.
The best results I've gotten so far at with X direction engraving (tired x_unilateralism but took 2x as long and didn't look much better) 800 speed and 0.08 interval @ 30 power (about 45% of max power) seemed to be the best looking setting so far. 0.09 interval also looked very comparable on larger letters and saved 20% on the time over 0.08 interval.
Here are my tests and notes. I hope by comparing notes we can all help each other get better. Any other settings you've tried which helps you get better engravings than these on your Chinese laser?
