CoreXY printer.cfg for EasyThreeD ET4000+ board

# CoreXY printer.cfg for EasyThreeD ET4000+ board

# * CoreXY
# * Sherpa Heavy like extruder

# I use ET4000+ main board for my CoreXY printer project.
# ET4000+ is MKS Robin Lite compatible.
# Motor ampere can be controlled via pwm pins: PB0 (xy), PA7(z) and PA6 (extruder).
# Original file is https://github.com/makerbase-mks/Klipper-for-MKS-Boards/blob/main/MKS%20Robin%20Lite%20V1.1/generic-mks-robin-lite-v1.cfg
# The firmware binary is also in the same GitHub directory.

# To use this config, the firmware should be compiled for the
# STM32F103RCT6. When running "make menuconfig", enable "extra low-level
# configuration setup", select the 28KiB bootloader, and serial (on
# USART1 PA10/PA9) communication.

# Note that the "make flash" command does not work with MKS Robin
# boards. After running "make", run the following command:
#   ./scripts/update_mks_robin.py out/klipper.bin out/mksLite.bin
# Copy the file out/mksLite.bin to an SD card and then restart the
# printer with that SD card.

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

# Beeper
# M300 : Play tone. Beeper support, as commonly found on usual LCD
# displays (i.e. RepRapDiscount 2004 Smart Controller, RepRapDiscount
# 12864 Full Graphic). This defines a custom I/O pin and a custom
# GCODE macro.  Usage:
#   M300 [P<ms>] [S<Hz>]
#   P is the tone duration, S the tone frequency.
# The frequency won't be pitch perfect.

[output_pin BEEPER_pin]
pin: PD2
#   Beeper pin. This parameter must be provided.
pwm: True
#   A piezo beeper needs a PWM signal, a DC buzzer doesn't.

shutdown_value: 0
#   Disable at emergency shutdown (no PWM would be available anyway).
