Hi, Thanks for the reply. Cameo doesn't have a clue as to what settings to use since styrene is not on their list of materials to use. I know others have used styrene with the Cameo with good results so I'm hoping to hear from them. The first time I used it on .015 styrene it worked great but didn't cut thru so I had to snap it but they were very clean snaps. I tried the deep cutter and more pressure (recommendations from Cameo) but that just made things worse.
