If the Silhouette is making loud noises and appearing to cut off track, or the motor appears to get stuck during the cutting process and throws off the proper alignment of the cut, this may represent that the motor is off track.

To correct this, you may attempt to manually move the motor to ensure it is on the track properly. To do this, please turn the Silhouette off and manually push the motor all the way to the left of the machine, and then all the way back to the right. It is possible the motor was slightly off track and was therefore making louder noises. After doing this, please turn the machine back on. Once turned on, the motor will travel back into place and should be ready to cut normally as before.  You may also seek to put a small bit of oil (such as WD40) or a graphite lubricant on the metal bar that holds the motor of the Silhouette in order to ensure the motor is able to travel back and forth without further concern.

Another concern which may display similar results and cause a noise and misalignment during the cutting process is if you have an older cutting mat where the edges are curling upward and thus catching on the motor as it travels along near the edge of the mat. If such is the case, you may simply need to replace your cutting mat as the edges become compacted and warped over time.

Finally, this issue can also be the result of your blade being overexposed where it is extended too far and catching during the cutting process. If you remove the blade and re-perform the job to have the Silhouette just go through all of the cutting motions without cutting and find that the issue disappears, then this would confirm a blade setting issue. If such is the case, please adjust the blade to a lower setting for your material.
