The Silhouette AutoBlade is specifically designed for use with the Cameo 3 and Portrait 2 models. With the AutoBlade, there's no need to manually adjust the blade.
The Silhouette Studio® software will suggest optimal cut settings for various materials, which you can modify as needed. Once you send the job to your Silhouette machine, the AutoBlade will automatically adjust based on the settings chosen in the software.
