I have been trying to cut coasters out of cork with a backing I got from lasersketch. I can engrave it perfectly but I can't cut through the 1/8" thick backing. Lasersketch said the use a 50w laser at 100% power and 5% speed with no problem. I try to cut it, no matter what power and EXTREMELY SLOW SPEED and all it does is pulverize the cork. They have no suggestions and neither do the tech guys from the laser dealer! Any ideas??
I'm a newbie but I'm getting the hang of everything pretty well but this has me very frustrated.
