I recently acquired a low watt laser engraver.  It’s an Etcher Laser, about half the price of a GlowForge. Easy to use.  I got it for the primary purpose of making my own embossing dies. I bought some small pieces of Delrin off of Amazon. They worked great. So, i bought a larger piece of Delrin from Professional Plastics.  When I tried to etch it, it didn’t etch deep and melted in the wake of the laser. As Delrin is a brand name, is there a certain type of Delrin I should be using? I’ve looked up information online, but everyone just says ‘Delrin’, as if there’s only one kind. I’ve spent good money on a piece of material I can’t use.  I don’t want to keep spending that much money just to try to find something that will work.
 
	Any suggestions?
