What happened?
The printer is displaying the message: Opening the project failed. The file is possibly corrupted. Please re-slice or re-export the project and try again.
Error name: Cannot read the project
Error code: #10539
This message appears when the file that has been requested to be printed cannot be read by the printer.
How to fix it?
Open the project in PrusaSlicer and slice it again. If the error persists, try slicing and printing another project, as it is possible that the model itself is damaged.
It is recommended to always use PrusaSlicer when printing for the Original Prusa SL1 & SL1S SPEED.
