Printing from USB with the Pro S

As an alternative to sending print jobs over your network, your SprintRay Pro S is also compatible with USB 3.0 or 3.1 flash drives. 

Note: The printer will not be able to read .STL files from the drive, print jobs must be prepared and saved as an .SPR file in RayWare.

When the USB drive is plugged into SprintRay Pro S, a USB Icon will appear on the left hand menu. Click on the icon to view the SPR files you have previously loaded onto the USB drive


Once selected, you will see any folders on the USB drive. Compatible files will be highlighted with white text, and incompatible files will be greyed out


Click on the desired folder until you find the .SPR file you loaded


Once you have selected a compatible .SPR file, you will see a preview of the files as well as the Print Job Settings, print time, and selected layer thickness


Selecting Add to Queue will add the print job to the list of queued prints


Selecting Print will begin the print job once you have completed the Print Readiness


Once ready, click the Start Printing button


If you're having issues with USB connection on a new printer, ensure that you're using a USB 3.0 drive

How do I tell if a USB Drive is USB 2.0, 3.0, or 3.1?

Unfortunately this is a little trickier than it should be. Manufacturers are supposed to color the internal plastic inside the plug to indicate it is USB 3.0 - but they do not always do so. The picture below details the common colors for each:
