The most common cause for the Silhouette CAMEO 3 not cutting or not cutting through is a problem with the blade - specifically the Autoblade.
If you are using the Autoblade in your CAMEO 3 it's important to make sure it's loaded into the blade carriage correctly to ensure it cuts. The Autoblade can only be used in the left carriage in the Silhouette CAMEO 3. The grooves on the back of the Automatic Blade should line up with the grooves on the left/red carriage on the CAMEO 3. Press the blade completely down and then lock it into place by pressing the tab all the way in. Here's a picture of the autoblade correctly positioned in the carriage.
If it looks like either of these two pictures, it won't cut correctly.
|Autoblade is not fully into the carriage and therefore will not cut|
|Silhouette CAMEO 3 Automatic blade is not fully pressed down into the carriage and therefore won't cut|
If the blade is correctly positioned in the Silhouette cutting machine, but the CAMEO 3 still isn't cutting correctly the next thing to check to make sure you have the correct blade selected in Silhouette Studio. When the CAMEO 3 is found, the Cut Settings window will include the AutoBlade in the Blade Type drop down menu. However, it's not the default. If you don't change the setting to the Autoblade the machine will think you are using the manually adjusted ratchet blade and will not adjust the Autoblade's blade depth resulting in no cut or a partial cut.
If the Autoblade is correctly in the carriage and you have it selected in Silhouette Studio, but the machine is not cutting anything - check your cut lines. If the machine appears like it's going to cut and then says "Job Complete" without cutting anything, the cut lines are not on.
Go to the Cut Settings window and with the designs you want to cut selected, pick "Cut" or "Cut Edge".
If you are using the ratchet blade in your Silhouette CAMEO 3 you can use it in either blade carriage. If the Autoblade isn't cutting correctly I always suggest testing with the ratchet blade as well.
If the ratchet blade isn't cutting in your Silhouette CAMEO 3 there are several things to check. First, make sure you have the blade press down into the carriage, with the fin facing directly toward you and that it's locked into place.
You'll also want to make sure the white cap is screwed on completely. If the white cap on the very end of the blade is not completely screwed on it will prevent the blade from reaching the material and therefore it can not cut. Twist it until it's hand tight.
Finally, you'll want to check to make sure that nothing is obstructing the blade such as dust from paper cuts or a small piece of vinyl.
