I try to print an object which print without problem. When I tried to duplicate this object in chitubox 1.9.0 (8 then 6 time), sliced it, then saved it on the usb key, the file doesnt appear on my Elegoo Mars pro, just like a folder, not an object. If I try to launch the folder icon, it says me file format unknown. The name of the file is short. What can I do?
