Error name: Internal memory full
Error code: #10516
Projects are copied from the USB flash drive to the internal storage, before the print (allowing to unplug the USB). Also, projects are uploaded to internal storage when sent directly from PrusaSlicer. This error is displayed when there is not enough internal space to complete the operation.
Delete files from the internal storage by swiping right on the file title and selecting Delete.
