The printer is displaying the message: The project must have at least one layer.
Error name: Not enough layers
Error code: #10540
This error happens when the project to be printed does not have enough layers to be printed.
The project must have at least one layer. Open the project in PrusaSlicer and re-slice it to make surer that it is not corrupted. In case the project was manually edited, make sure to add more layers to it.
