I've got a sheet of ALUM354 from JDS Industries here. Been trying to get it to engrave to a good gold color on my 100watt laser, but having no such luck. I can either blow through the gold and expose the underlying silver color of the aluminum, or the black doesn't come off. Can't seem to get anything in between. I did the same job on my smaller 40 watt laser, and can get a decent result however. But, working on a job that's bigger than the table on my 40 watt. Has anyone had any luck with this material, and if so, what settings, etc. did you use to get it to actually look gold when done?
Thanks.
