14W J-Tech vs Pmag

Just curious if anyone has attempted to engrave Magpul/Pmag using the J-Tech 14W. If so, how did it go? Willing to share settings?

I’ve done several and it works pretty well for “burning”polymer. Not on the Jtech though. It etches easily and they are cheap enough to have one or 10 to practice on.

Kydex does well too.
