# 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
#   PWM frequency : 0.001 = 1ms will give a base tone of 1kHz
scale: 1000
#   PWM parameter will be in the range of (0-1000 Hz).
#   Although not pitch perfect.

[gcode_macro M300]
default_parameter_S: 1000
#   Use a default 1kHz tone if S is omitted.
default_parameter_P: 100
#   Use a 10ms duration is P is omitted.
gcode:
    SET_PIN PIN=BEEPER_pin VALUE={S}
    G4 P{P}
    SET_PIN PIN=BEEPER_pin VALUE=0

# 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.
