+# This file contains common configurations and pin mappings for the Prusa Buddy
+# board. The LCD is not currently supported by Klipper, so the touchscreen will
+# permanently display the bootloader screen after the Klipper firmware is flashed;
+# use Fluidd, Mainsail, or OctoPrint etc. to control the printer.
+
+# To use this config, the firmware should be compiled for the STM32F407. When
+# running "make menuconfig", enable "extra low-level configuration setup",
+# select the "128KiB + 512 byte offset" bootloader, and USB communication.
+# Connect the printer to your Raspberry Pi using the printer's micro-USB port.
+# If you prefer to remove Prusa's stock bootloader entirely, select the
+# "No bootloader" option.
+
+# When flashing for the first time, you will need to break the "appendix"
+# on the Buddy board, then put the device into DFU mode by moving the jumper
+# on the 3-pin header (older boards) or shorting the 2-pin header (newer boards)
+# and resetting, and finally use "make flash" to install Klipper. Once Klipper is
+# installed, you no longer need the jumper - just use "make flash" which will
+# automatically put the device into DFU mode.
+
+# Note that if you were previously running Prusa firmware, you must fully
+# power cycle the board after flashing. Otherwise, Klipper will be unable to
+# communicate with the TMC2209s due to the abrupt change in the baud rate,
+# and will show this error: "Unable to read tmc uart register IFCNT".
+
+# See docs/Config_Reference.md for a description of parameters.
