######################################################################
# 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]

# Use a default 1kHz tone if S is omitted.

# Filament Change
######################################################################
# M600: Filament Change. This macro will pause the printer, move the

# been changed, the print can be resumed from its previous position
# with the "RESUME" gcode.
