# This file contains common configurations and pin mappings for the Prusa
|
|
|
|
|
# Mini+, which uses the Prusa Buddy board. The printer's 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".
