I recently purchased and received (3 days ago) my first 3D printer, a CR10S Pro and Im having issues already. Im downloading print files from thingiverse and slicing them with Cura. I have printed 5 or 6 simple prints but my printer wont recognize anything I really want to print. Ive tried deleting them and reloading and reslicing; tried restarting PC, printer and programs; checked to make sure I have the recent firmware for the printer (1.60.3); tried plugging the printer into my PC via the supplied USB cord but Cura will not recognize the printer is connected. Im lost and not very sharp with this sort of thing. Any help would be greatly appreciated!
