What happened?
The printer is displaying the message: The internal memory is full, the project cannot be copied. You can continue printing - however, you must not remove the USB drive mid-print, otherwise, the process will fail.
Error name: Can't copy project
Error code: #10704
How to fix it?
Usually, once a model is loaded to the printer by a USB drive, you do not need to keep the USB connected to finish the print, as the SL1 will copy the model to its memory. When the Printing directly error message appears, it means that the printer cannot copy the file to its internal memory due to it being full. In order to print, you have two options:
- Printing directly from the USB drive, and not removing the USB from the SL1 during the whole print.
- Deleting some files from the printer. You can do that by going to the printer menu in the LCD menu -> Print and swiping the file to the left. It will display the trash bin icon which can be tapped to delete a file.
