Look for the Chipp Walters KitOps youtube instruction vids, and with KitOps Free and Pro is also a comprehensive online documentation available. All if not most answers will be there.

Obviously you can use the inserts as they are, but f.e. especially the cutters can be mangeld to your hearts desire (scale, rotate, stretch, etc)
