What happened?
The printer is displaying the message: Analysis of the project failed.
Error name: Project analysis failed
Error code: #10542
The printer can fail to analyze the project if it has been manually edited, or if the project was sliced in a slicer incompatible with the Original Prusa SL1/SL1S Speed.
How to fix it?
In case you find the error, try slicing the file through PrusaSlicer.
