As an alternative to sending print jobs over your network, your SprintRay PRO is also compatible with USB 3.0 flash drives.
The printer will not be able to read .STL files from the drive, they must first be converted to .SPR files in Rayware 2.0 or later.
When the USB drive is plugged into SprintRay PRO a new tab labeled 'external' should pop up on the screen and display all .SPR files on that drive.
If you're having issues with USB connection on a new printer, ensure that your printer is on firmware 5.176 or later, and that you're using a USB 3.0 drive
How do I tell if a USB Drive is USB 3.0?
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. In the picture below the two drives on the left are USB 3 and the one on the right is USB 2.
If you're still having any issues printing with your SprintRay PRO, don't hesitate to reach out to our customer support team for additional assistance.
