Getting the beeper on the SV07 to work by using a shell-script takes two files:

1. `macro_beep-beep.sh`

```bash
#!/bin/bash
# usage: beep.sh [BEEPCOUNT] [BEEPDURATION] [PAUSEDURATION]

# Output raw passed parameters
echo "Raw parameters: $@"

# Default values
BEEPCOUNT=${1:-3}
BEEPDURATION=${2:-0.1}
PAUSEDURATION=${3:-0.5}

# Output all passed parameters
echo "Beep count: $BEEPCOUNT, beep duration: $BEEPDURATION, pause duration: $PAUSEDURATION"

# Function to play a beep
play_beep() {
    echo 1 > /sys/class/gpio/gpio82/value
    sleep $BEEPDURATION
    echo 0 > /sys/class/gpio/gpio82/value
}

# Play the beep for the specified count
for (( i=0; i<BEEPCOUNT; i++ )); do
    play_beep
    sleep $PAUSEDURATION
done

```

1. `macro_beep.cfg`

```auto
[gcode_macro BEEP]
gcode:
  {% set beep_count = params.BC|default("3") %}
  {% set beep_duration = params.BD|default("0.2") %}
  {% set pause_duration = params.PD|default("1") %}
  RUN_SHELL_COMMAND CMD=beep PARAMS='{beep_count} {beep_duration} {pause_duration}'

[gcode_shell_command beep]
command: bash /home/mks/printer_data/config/macro/macro_beep-beep.sh
timeout: 10
verbose: False

```

- adapt the path to the script-file in `macro_beep.cfg` (third line from the bottom)
- include `macro_beep.cfg` in your `printer.cfg`
- then, you may use e.g. `BEEP BC=5 BD=0.1 PD=0.5` in other macros (PAUSE, PRINT\_END, …)
