After you've saved a print job, you can preview your sliced .SSJ files using the "View Print Job" function in RayWare under the file menu.
On this screen, you can load in your sliced .SSJ files and RayWare will preview layer-by-layer how it intends to print your design. This is incredibly valuable to check that all overhangs are supported and no unusual file glitches have made it through to the print job.
