I have the Refine MH 721. I'm very happy with the cutter but I have a problem with not knowing where it will start cutting and I am wasting lots of material. When I click on "Cutter", I fisrt click "Home Position" then click on "Tile". Sometimes it cuts the Tile first, sometimes the design first, sometimes it will advance a few inches of vinyl before starting to cut, sometimes it starts cutting from where it is. I'm having to cut my work with 6-8 inches of vinyl hanging out the front of the cutter to asure a good cut without running off. Can anyone tell me what I'm doing wrong? Thanks for any help..... I moved up from a Dr. Stika 12" to the Refine 24", what took me so long? This thing is a Cutting MONSTER........ I love it..
