What happened?

On the Original Prusa XL, communication with the peripheral boards (e.g. Dwarf 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 Original Prusa XL firmware, the master is the XLBuddy, and each slave is called puppy.

To be able to establish communication with the puppies, each puppy is assigned a unique address that is used by the XLBuddy. If the XLBuddy finds a puppy without an assigned address, the printer will show the message: "Unassigned puppy found".

Error name: Puppy no addr

Error code: #17512

How to fix it?

Re-flash firmware

Download the firmware and if necessary the bootloader, and transfer it to your USB drive. Make sure to unmount the drive from your operating system before physically removing it.

Insert the USB drive back into the printer and reboot the printer using the reset button directly next to the knob to initiate the flashing procedure. In case the procedure does not start, reboot the printer again by pressing the same reset button, and while the printer is booting up, press once the rotating knob.

A visual inspection

Before accessing any of the electronic boards, ensure that the printer is fully cooled down, and switched off for at least 10 minutes

Inspect the wiring on the Sandwich board for a cable positioned into an incorrect port, a loose connection, or a broken cable.
