I know this is an old post but how big a laser are you guys using. I tried to get one done by a mate with a 40w epilog and he couldn't seem to get any depth. I bought the machine off him second hand the other day and thought i might try a few out but just curious. Would i need to somehow vector cut the design??? still learning this laser stuff, but would love to be able to make custom stamps for my work rather than learning to carve
