Hi @mrsrosenberg , [br]
You copy the file onto the SD card that came with your JellyBOX and plug in into the SD card slot on the top left of the printer. Then you Select ‘Print from SD’ using the rotary selection button. [br]
In general, printing from a ‘local’ storage like an SD card is more reliable than printing over USB, even though that’s possible as well using Cura Imade3d Edition. [br]
/ I recommend posting to forum.imade3d.com for general questions - it’s a more responsive place.
