Why can't the Precision Base Plate be used with the Big Shot Foldaway or Sizzix Plus Machine?

As we develop new machines we look to enhance the pressure to accommodate the performance required for more intricate designs. As a result, the Big Shot Foldaway has adequate pressure without the need for the Precision Base Plate, so we don't recommend its use with the Big Shot Foldaway. Use of the Precision Base Plate in the Big Shot Plus and Big Shot Foldaway will result in reduced cutting pad and die life. Do NOT use the Precision Base Plate in any machine with steel-rule dies as damage may occur.
