Just something that bothers me slightly, Xtool would have an extensive amount of testing data on their products and modules. So why is material reference so incredibly limited ?

I can't find a decent reference for plywood 10mm thick on a 40w laser for instance. Or glass engraving settings on that same module, or mirror engraving settings for a 2w IR laser module. I have started to create my own material reference in excel, but it just feels inadequate for Xtool to provide so little support or reference here.

Maybe a community based reference (with for instance EAN codes of used materials as reference) could be a good starting point ?
