Why Is My Silhouette Cutting Random Lines?

Many Silhouette users have experienced a common issue when cutting with their machine: random lines cutting into their project. This issue can be caused by a few different things, so it is important to determine the cause of the random lines before attempting to fix them.

One possible cause of random lines cutting into your project is simply the blade being too deep. If your blade is not set correctly, it can cut too deep and create unwanted lines in your project.

To check if this is the cause of your issue, remove your blade and check that it is correctly adjusted for the material you’re cutting. If it is not, adjust it accordingly and re-insert your blade.

Another possible cause of random lines could be debris or bits of material stuck in the Silhouette machine’s roller bar or in the grooves of your cutting mat. To fix this issue, use a lint roller or sticky tape to clean out any debris that may be stuck in these areas and then try cutting again.

Finally, if you’re using an older model Silhouette machine, there could be an issue with its design that causes random lines to appear on projects. In this case, you may need to contact Silhouette customer service for help troubleshooting and resolving this issue.

No matter what the cause of random lines on your projects is, there are steps you can take to diagnose and fix this problem quickly and easily so that you can get back to creating beautiful projects with your Silhouette machine!


In conclusion, random lines appearing on projects when using a Silhouette machine can have several causes but they can all be fixed by checking that the blade is properly set, cleaning out any debris from its roller bar or grooves of the mat, or contacting customer service for help if using an older model machine. Regardless of what the cause may be, following these simple steps will help ensure that you get back to creating beautiful projects with ease!
