Perhaps you could cut the mask on the stone with a router then blast it .
Havent tried that yet , but need to try it for more detail ,weeding small stuff is a pain.
What are you making ?

it can be done but it is also a pain and generally ruins the mask although i have used my laser to cut through mask that has been applied to the stone and then i blast it , also just some info 3m just relaeasd a new mask that is a high tack baking it works awesome if you experiance blow off while blasting (but duck tape really is the trick...phht for maski material ive tried it and it lasts about 2 seconds.) i have also cncd lexan to use as a mask on some flat stones the laser will cut way more detailed stuff ont he mask than the router
