No worries! Glad to help whenever and wherever I can on these sorts of things. It’s because of other forum members that I’m where I’m at, so it feels good to give back.
Alright, so first and foremost, when working with anything that is non-proofgrade material, you’ll want to manually enter the material height. This can be done by uploading your design, and on the glowforge interface clicking the “unknown” (or in some cases, changing the last used proofgrade option) and selecting the option use uncertified materials found towards the top right of the dialogue. In my case these tiles are about .3 inches.
After choosing that, you’ll have to manually change your layer settings by clicking on each individual layer and changing the settings. So the very top slider is speed which can vary between 1-1000 the next slider is power which can vary between 1-100-full power which can be confusing, but those are the options The LPI or lines per inch is how many times the laser will etch a line within a square inch, in my case 450 lines within that inch.
Ah, I see that @rbtdanforth was also able to help answer!
