Hi folks, I got some samples from Rowmark and don't quite know what to do with them? Can I etch photos on them? I've got a 80watt Trotec Speedy 300 and am trying to learn every thing I can, but don't know much about the plastics. I know cast, and Extruded from what I've read. This seems like an altogether to big of a question for this forum. So can anyone point me in the right direction for a crash course in Me, Plastic, and my amazing machine. I'm getting the wood down, The Granite and Marble, still working on glass. My rotary is all kinds of fun. But I have yet to touch the plastic end of things.When I finale go into business this spring I can't help but think plastics will be a big part of it. Any suggestions would be much appreciated. Thanks, this site has been a big help to me....Jeff...
