# This file contains common pin mappings for the Monoprice
|
||
|
|
# Select Mini v1. To use this config, the firmware should be compiled for the
|
||
|
|
# STM32F103 microcontroller with an 8MHz crystal and USB for communication.
|
||
|
|
#
|
||
|
|
# Use the following settings in make menuconfig:
|
||
|
|
#
|
||
|
|
# * Enable extra low-level configuration options: Enable
|
||
|
|
# * Microcontroller architecture: STM32
|
||
|
|
# * Processor: STM32F103
|
||
|
|
# * Bootloader offset: 8KiB bootloader
|
||
|
|
# * Clockspeed: 8 Mhz crystal
|
||
|
|
# * Communication interface: USB (on PA11/PA12)
|
||
|
|
# * GPIO pins to set: PA8, PB1, PB11, PB9
|
||
|
|
#
|
||
|
|
# IMPORTANT: A bootloader offset of 8KiB will preserver the stock bootloader
|
||
|
|
# and allows easy flashing via SDCard without additional hardware.
|
||
|
|
#
|
||
|
|
# IMPORTANT: Setting PB9 in the the GPIO pins to set at micro-controller
|
||
|
|
# startup is required for the USB port to function.
|
||
|
|
#
|
||
|
|
# PA8, PB1, PB11 in the GPIO pins deactivates the steppers until klippy
|
||
|
|
# takes over.
|
||
|
|
#
|
||
|
|
# Note 1: Prior to flashing klipper, if possible, make a copy of the default
|
||
|
|
# or current configuration values for the printer. Running an M503 command
|
||
|
|
# will output these values.
|
||
|
|
#
|
||
|
|
# Note 2: Klipper can be flashed by copying out/klipper.bin to the MPSMv1's
|
||
|
|
# SDCard, renaming it to update.bin, and creating an empty file on the SD card
|
||
|
|
# named fcupdate.flg. Insert the SDCard while the printer is off it on. After
|
||
|
|
# klipper is flashed, remove the SDCard and delete update.bin and fcupdate.flg
|
||
|
|
# to prevent the firmware from flashing on every subsequent power-on.
|
||
|
|
# Returning to stock firmware without a programmer is possible as long as the
|
||
|
|
# bootloader is not overwritten.
|
||
|
|
#
|
||
|
|
# Note 3: Stepper directions are not consistent in MSPMv1 printers. Check the
|
||
|
|
# directions of the printer with M503 in the stock firmware and adjust the
|
||
|
|
# dir_pins below accordingly.
|
||
|
|
#
|
||
|
|
# Note 4: Klipper currently does not support the LCD-UI of this
|
||
|
|
# printer, which is connected via serial interface and controlled by an
|
||
|
|
# esp8266 using a custom protocol.
|
||
|
|
#
|
||
|
|
# See ../docs/Config_Reference.md file for a description of all parameters.
