I've been using the scraper tool that's provided with the Flux printer to both remove the printed model from the base and to remove the raft from the printed model afterwards. I don't know how it happened, but the scraper tool has developed a chink, or a chip. In trying to remove old glue from the baseplate, I have put a terrible gouge in the metal. It will work still, but it's ugly. If you run your finger along the edge of the scraper tool, you can feel the chip in it… Or you might call it a burr. So be careful out there!
