First off - I’m a newbie.
I would like to engrave some black powder coated aluminum flasks. Below is the result of my first attempt using the “Silver MacBook Pro” setting that I had seen mentioned. The flask is slightly rounded.
I cleaned the flask with acetone after engraving hoping the aluminum will shine through, but it hasn’t helped much. I would like a slightly deeper cut to see if that helps. The laser made 1 pass on this setting.
Any suggestions on settings that will allow the aluminum to shine through??
First picture is before cleaning, second is after acetone cleaning.
Hey @epconrad, I went ahead and moved this to the “Beyond the Manual” section as it deals with non proof grade materials. It looks pretty good to me honestly…I will go back on a post I made to see what settings I used on a similar flask
It said powder coated… but I really wouldn’t know the difference. I’m trying it again with 100 power, speed 500 and 400 lpi. 1 pass. We’ll see what happens.
Hope the new setting worked out for you. Just in case you didn’t know, as long as you don’t move the material on the tray or the file in the GUI, you can run it again it will line up perfectly. (Even if it looks slightly off on the preview.) It makes it easier to start off conservatively and just do multiple runs if need be.
