If your print head on your Sabre Automatic is starting extended to the outside of the machine, you will need to change the setting on your tablet.  You will need to select the print head that needs to be changed so that the settings will appear.  The setting that will need to be changed is labeled Home Position.  If the Outer option is selected the print head will start with the chopper in the fully extended position.  If the inner option is selected the chopper will start closer to the center of the machine.
