printer.cfg
# This file contains common pin mappings for the BIGTREETECH SKR
# MINI 2.0. To use this config, the firmware should be compiled for
# the STM32F103 with a "28KiB bootloader". 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 SKR mini. 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 SKR
# mini with that SD card.

## *** THINGS TO CHANGE/CHECK: ***
## MCU path [mcu] section
## Z and Extruder motor currents [tmc2209 stepper_*] sections. Uncomment the stepper motor you have
## Full steps per rotation for Extruder [extruder] section
## Thermistor types [extruder] and [heater_bed] sections - See 'sensor types' list at end of file
## Extruder motor currents [extruder] section
## PID tune [extruder] and [heater_bed] sections
