"i just got my first laser and i bought this based on the reviews. Unfortunately i probably won't even use the file because I didn't realize Lightburn now has the "material test" feature built into it, haha! So, haven't used the file and I probably won't, but I'm sure it would've been great 🤦🏻♂️
**UPDATE**
I tried using the material test feature in Lightburn and it kept stopping mid-burn as if the power gets cut. I tried several times with the same results. So i thought I'd try these files and wouldn't you know?? Success! Very strange, but these material test files worked great. Plus, they're just a better material test in general. Very nice, thanks so much!🙌🏻"
