klipper/config/printer-sunlu-t3-2022.cfg

# This file contains common pin mappings for the SUNLU Terminator T3 board

# To use this config, the firmware should be compiled for the
# STM32F103 with a "28KiB bootloader" and USB communication.
# Select "Disable SWD at startup (for GigaDevice stmf32f103 clones)"
# Also, select "Enable extra low-level configuration options" and configure
# "GPIO pins to set at micro-controller startup" to "!PA14".

# The "make flash" command does not work on the SUNLU Terminator T3 board. Instead,
# after running "make", copy the generated "out/klipper.bin" file to a
# file named "firmware.bin" on an SD card and then restart the board with that SD card.

# See docs/Config_Reference.md for a description of parameters.

# Rename the file to printer.cfg
