A lot of people do that. I don't have a Crafty but have other vaporizers that have glass mouthpieces.
You can scape off the resin with a thin tool such as they use with dabbing. Just put the resin inside some cotton and vape away. You can sandwich some bud with some resin too. Often the resin isn't that tasty. The nice tasting cannabis can hide the taste a bit.
Wipe out your unit after you are done while it's still warm to clean.
I actually scraped it all gently out of the crafty and got a glob of stuff that tasted similar from the wax I tried but not as good. I am glad you guys told me though. Good for HOURS.
