Engraving brass rifle casings

Welp with the help I recieved yesterday I was able to get through 8 different test case scenarios that allowed me to find the right settings for engraving brass with LazerBond 100 coating.

Happy camper!!!

Would you share your machine power settings and speeds for this success? My attempt with the same product resulted in a coating which abraded too easily, which resulted in my surrender.

Sure Fred.

Brass cleaned with acetone.
Good coat of coating.
Speed 1mm/sec
21mA for power
Fill only.

It looks like it came out pretty nice, but I’m having a hard time with the “1mm/sec” part…

That’s about 2.36 inch / minute

If that text is 1 inch long and 1/8" high, and you scan at 500 lines/inch, that’s 1524 seconds or more than 25 minutes to complete the job and that’s not even including the overscan distance/time which probably adds 50%.

Is that correct? Is it really taking more than 30 minutes to do that job? Or do you have something mixed up in the units setup?
1mm/sec is just dead slow.

edit to add: The settings in your video in the other thread also show 1mm/sec, but the laser head is quite clearly moving MUCH faster than that.

I noticed that as well. Is the controller ignoring your speed setting? Does it show the 1mm/sec on the controller panel when it’s running?

You know guys let me check that. Could I have made a setting change that would ignore the input?

I took a video this morning of the settings and show the speed on the controller.
