My son is just getting into Solidworks and 3D printing, he's 12. He claims he can't send his SW files to the Da Vinci 1.0 jr printer...only uses SD Card? Yet it's hooked up to the computer and on wireless. This doesn't sound correct to me. We have to buy an USB SD adapter, hook it the desktop (most don't have SD slots anymore), and then transfer the SD back to the printer. Does this sound correct? Again, we're just beginning with Solidworks and 3D printing.
