My metal lathe didn't come with an ID plate on it, and come to find out that the seller can't get them any longer. So I found a pic of what it should look like, and then create an image for my fiber laser to cut. I am using stainless steel in this video, but still have to try mild steel and aluminum to see how they turn out. As you can see, the heat from the laser has actually warped the plate a bit, so I would need to straighten it before I could mount it onto the laser end cover. No big deal, but I might want to try different settings on the laser to reduce the heat and maybe eliminate that warping I am getting.
Been finding that there are lots of settings that even minor changes in them can make a lot of difference in the engraving/marking. So yeah, definitely a learning curve that I am still climbing.....
