On the Prusa CORE One/+ and Prusa CORE One L, communication with the xBuddy extension board is achieved using the MODBUS protocol. In MODBUS, there are two types of devices: the master and the slave, also known, respectively, as client and server. On the firmware, the master is the xBuddy, and each slave is called puppy.
The CORE One firmware includes all the needed files for xBuddy and puppies, including bootloaders. In case an incompatible bootloader is flashed, the printer will show the message: "Puppy uses incompatible bootloader protocol #, Buddy FW requires #".
Error name: Puppy incompatible bootloader
Error code: #31515 (CORE One) #35515 (CORE One L)
The error indicates most likely a configuration problem that might have stemmed from the firmware, or a faulty connection of the xBuddy extension board.
Access the xBuddy and xBuddy extension boards by loosening six M3x4bT bolts to remove the cover. Once visible, check the boards for visible damage on their surface, and check the connection between xBuddy and xBuddy extension for any irregularities.

To access the CORE One L electronics, the first step is locating the Wi-Fi module on the rear panel of the printer. Using a 2.5 mm Allen key, remove the M3x14 screw. Gently pull the Wi-Fi module straight downward to remove it from the printer.

From the inside of the printer, locate on the rear side the highlighted M3x4bT bolts.
Using a T10 Torx key, remove two M3x4rT bolts to release the rear xBuddy box cover. Lift the cover to expose the xBuddy and xBuddy extension boards.
Once visible, check the boards for visible damage on their surface, and check the connection between xBuddy and xBuddy extension for any irregularities.
