# 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: ar37
#   Beeper pin. This parameter must be provided.
#   ar37 is the default RAMPS/MKS pin.
pwm: True
#   A piezo beeper needs a PWM signal, a DC buzzer doesn't.
value: 0
#   Silent at power on, set to 1 if active low.
shutdown_value: 0
#   Disable at emergency shutdown (no PWM would be available anyway).
cycle_time: 0.001
#   Default PWM frequency : 0.001 = 1ms will give a tone of 1kHz
#   Although not pitch perfect.

[gcode_macro M300]
gcode:
    # Use a default 1kHz tone if S is omitted.
    {% set S = params.S|default(1000)|int %}

# Filament Change
######################################################################

# M600: Filament Change. This macro will pause the printer, move the
# tool to the change position, and retract the filament 50mm. Adjust
# the retraction settings for your own extruder. After filament has
# been changed, the print can be resumed from its previous position
# with the "RESUME" gcode.

#
# Note the format of the parameter SENSOR in the macro below.  The BME280
# sensor status can be accessed using the format "bme280 <section_name>".
# The example section above is named "my_sensor", thus the bme280 can be
# queried as follows:
#
# QUERY_BME280 SENSOR='bme280 my_sensor'
#
# Since a default parameter is defined one could simply enter QUERY_BME280
# as well.

# Override M117 command with rawparams
######################################################################

#
# It uses the rawparams pseudo-variable that contains the full unparsed
# parameters that was passed to the M117 command.

# As this can include comments, we are trimming the text when a `;` or `#` is
# found, and escaping any existing `"`
