What happened?
The printer is showing the message: "Puppy # firmware not found".
Error name: Puppy FW not found
Error code: #31518
The error message includes the name of the puppy board where the firmware was not found. The firmware for all puppies is part of the Original Prusa CORE One firmware file. The error is triggered when the indicated puppy firmware is not found as part of the firmware file.
How to fix it?
Ensure the printer is cold, switched off, and disconnected from the mains before accessing its electronics.
