How to run single command on 3D printer using picocom
In our previous post How to connect to your 3D printer using picocom we showed how to open an interactive serial session on the command line using picocom
. But you can also use picocom
to run just a single command such as the M997
firmware update command:
echo "M997" | picocom -b 115200 /dev/ttyACM0 --imap lfcrlf --echo
If your USB serial device is named /dev/ttyUSB0
instead of /dev/ttyACM0
you can use this alternative version:
echo "M997" | picocom -b 115200 /dev/ttyUSB0 --imap lfcrlf --echo
