What happened?
The Prusa CORE One is a CoreXY printer with a chamber. In some particular GCodes, especially customized commands, an upward movement after a downward printer movement might be programmed, but this carries the risk of a collision between a printed model and the chamber ceiling.
In that case, the printer shows the warning message "The printer queued a move that may crash the model into the ceiling" before printing.
Error name: Ceiling clearance violation
Error code: #31112
How to fix it?
Before proceeding with printing the file, it is recommended that you double-check your printable file to ensure that no upward movements are programmed or expected after a downward print movement.
