topic_solved How to run gcode commands remotely on a Duet3 + RPi?
TDK last edited by
I have a Duet3 6HC board connected with a Raspberry Pi. It works, I can print files, view the web interface, etc. Is there a way I can programmatically (Python) run commands remotely on this setup? I have it set up where I can telnet into the RPi, but obviously entering gcode commands in the console doesn't work.
I also have a Duet2 Wifi board where I can telnet into the board and just send commands to run them. I'm essentially looking for the same functionality on the Duet3 + SBC setup.

There is a phyton api if you search the forum
and if you just want to run code from the console then on the pi do
/opt/dsf/bin/CodeConsole(sudo if needed?)

sudo /opt/dsf/bin/CodeConsolefrom the console seems to work.
Here's my code to log in using Python with the default user/pass. After this, sending commands works:
tn = telnetlib.Telnet(printer_ip) print(tn.read_until(b"login: ").decode('utf=8', errors='ignore')) tn.write(b'pi\n') print(tn.read_until(b"Password: ").decode('utf=8', errors='ignore')) tn.write(b'raspberry\n') print(tn.read_until(b"$ ").decode('utf=8', errors='ignore')) tn.write(b'sudo /opt/dsf/bin/CodeConsole\n') print(tn.read_until(b"Connected!").decode('utf=8', errors='ignore')) tn.write(b'M114\n') sleep(1.0) print(tn.read_very_eager().decode('utf=8', errors='ignore'))

they've started moving away from running as root so wasn't sure if that applied to CodeConsole or not.
you can also pipe commands for a one off
echo M114 | sudo /opt/dsf/bin/CodeConsole
(edit: you could also run the whole thing securely over ssh from another host as single command
ssh pi@printer_ip "echo M114 | sudo /opt/dsf/bin/CodeConsole"(use with public key in authorized_keys (
ssh-copy-id pi@printer_ip) and specify
ssh -tor set up sudo on the remote host to not require password for the command in question))
