This is the script I use to print something on my 3D printer via TRIGGERcmd. It turns the printer on, prints the object, then turns it off again.
#!/bin/bash -v
tcmd --computer "octopi" --trigger "3d printer smart plug on"
sleep 10 # wait for the printer to boot
octoprint-cli connection connect
octoprint-cli print select $1.gcode
octoprint-cli print start
# Loop until print job is finished
while true; do
# Retrieve job status
job_state=$(octoprint-cli print status | head -n 1)
# Check if the job is finished
if [[ $job_state == "Printer Operational" ]]; then
echo "Print job finished."
break
fi
# Wait for the next check
sleep 10
done
tcmd --computer "octopi" --trigger "3d printer smart plug off"
My /root/.TRIGGERcmdData/commands.json file looks like this:
[
{"trigger":"Reboot","command":"shutdown -r","ground":"background","voice":"reboot","allowParams": "false"},
{"trigger":"3d printer smart plug on","command":"echo","ground":"background","voice":"plug on","allowParams": "false"},
{"trigger":"3d printer smart plug off","command":"echo","ground":"background","voice":"plug off","allowParams": "false"},
{"trigger":"Start 3d print","command":"su - pi /home/pi/print.sh","ground":"background","voice":"print","allowParams": "true"},
{"trigger":"apt update","command":"apt-get -y update","ground":"background","voice":"update","allowParams": "false"}
]
It uses two Alexa routines - one to turn my Wyze smart plug on, and one to turn it off (to turn the 3D printer on/off). This is a screenshot of the "off" routine:

This article explains how to setup the Alexa routine.
