I have started a material library in LightBurn based on the following material settings spreadsheet provided by Elegoo:
Elegoo PHECDA 20W.clb (10.8 KB)
Please note: this only includes the material settings for the 20W version of the laser, with the exception of “A4 Paper” for which I just halved the max power for some initial test cuts. If there’s any interest I will create another library file for the 10W device. Suggestions for further materials to add would be appreciated, and feel free to note any errors or improvements you’d suggest as I am new to laser cutting and engraving.
