Loosely connected segments and vibration
This limitation does not come up too often, but it is worth keeping in mind, particularly if you are making signs with lettering or logos. If your part has an “island” connected to the main part by a single, very thin segment (also called a bridge), the island area will often vibrate as it is being cut, ruining the smooth cut line. For this reason, we suggest making connectors at least 1/8 inch (3 mm) thick, and placing at least 3 on each island area.

Similarly, connecting segments themselves can vibrate, causing the segment to be destroyed during cutting. Again, make sure that the bridge is at least 1/8 inch (3 mm) wide.
