I have either an Instone printer,or an Aladdin Skycube 3d printer,it is an unbranded version but looks like them. Anyway,I can only print the files that came on the SD card. I have tried 3 different slicers but still the prints I download all look horrible. I do not have a data cable to hook it up to the printer. I am frustrated and disappointed. What to do? Any help would be appreciated.
