Power off printer after print finishes

maciekish

Hi,

How can i run a shell script after a print job finishes? I want to power off the printer via GPIO.

See manual advanced setup how to define programs you can execute. Define a command you can run with @execute unpower_printer for example. That can be a simply python script toggling the pin.

I saw @execute but where do i put that?

maciekish

Printer settings, g-codes, event dependent?

I think event dependen for print finished event as last command would be a good place. At least if you want it after every print. If it should just be a menu entry just add it to commands.

Cant get it to work

I put @killprinter in Run after job and have the following extcommands.xml:

    <config>

        <command>

            <name>Power on Printer</name>

            <execute>gpio write 8 0</execute>

        </command>

        <command>

            <name>Power off Printer</name>

            <execute>gpio write 8 1</execute>

            <confirm>Really power off the printer?</confirm>

        </command>

        <command>

            <name>Shutdown Server</name>

            <execute>sudo /sbin/shutdown -h now</execute>

            <confirm>Really shut down the server?</confirm>

            true

            true

            true

            true

            true

            true

        </command>

        <command>

            <name>Reboot Server</name>

            <execute>sudo /sbin/shutdown -r now</execute>

            <confirm>Really reboot the server?</confirm>

        </command>

        <execute name="killprinter" allowParams="false">/var/lib/Repetier-Server/killprinter.sh</execute>

    </config>

killprinter.sh (it is executable and readable by the repetier-server daemon user and gpio pins are accessible because the menu commands to power on and off the printer do work):

    #!/bin/bash

    sleep 3

    gpio write 8 1

I also tried sudo -u repetierserver /var/lib/RepetierServer/killprinter.sh manually after finishing a print and it shut the printer down like it should.

You know the command is not @killprinter but

@execute ;killprinter

You say which commands can be executed with @execute not the names itself.

maciekish

Still not working with that command..

Just saw there is a semicolon in my example which is of course wrong an only a type.
