Got it figured out... I was going off the Material loading guide from the USCutter website, which uses the same "U" shaped stickers in the guide photos. The meaning for the stickers, however, is the exact opposite on the Titans, since apparently the guide photo has a huge grit roller, with a small dead space, and the Titans have a huge dead space, and a smaller grit roller. I figured it out while waiting for Technical Support, which were really nice by the way.
Chalk it up to my excessive "noobie-ness". I've never even seen a cutter before, so all I had to go off of was the photos. Doh!
Thanks for the tip on giving extra on the roll. I probably would have let the cutter do all the work.
Here' the guide that caused me problems...
