Just a couple of questions. How many layers of fabric were you cutting? If multiples, you might want to try a smaller number of layers. If the die has a straight line cut, you don't want to feed that into the machine where that blade is perfectly parallel to the roller. Most of the dies are placed on the die block on an angle to avoid this. If possible (and it's not always possible) feed the die in at a slight angle. And lastly, how high was the cutter positioned? Too high or too low will cause problems. Also, the GO does seem to loosen up a bit thru use.
