Throwing away some scrap cardboard or scratch paper beats a miscut $10 piece of foam any day. If it turns out I want to use a lot more of this material, I plan to try some 3M VHB transfer adhesive. Reducing the laser pulse frequency can also be a useful knob to turn but it's more fussy and can result in perforated cuts. 1 AI File 1 EPS File 1 PDF File 1 JPG File 1 CSH File 1 … I use the Epilog lasers at TechShop SJ for cutting and engraving all sorts of things, but the way I test a new material is pretty much always the same.
