If you mean that it's not advancing, then I think it may be the roller needs adjusted. I did two things, but not quite sure which helped it. The first thing I did was loosened the middle support screw for the roller. You might be able to adjust it without taking the bottom off, on mine it's located just above the fan. The other thing I did was took the stepper motor end off of the cutter and noticed the belt was off a little. So I adjusted it to where it should be. So, if it's just sitting there cutting a straight line across the vinyl and making a buzzing, grinding type noise, then that may be it.
