    End Stop to Power Off Printer

    Description

    I use Octoprint to make my printer wireless with a Rapide Lite. But i need a way to shutdown my printer when not at home.


    I created a End Stop holder and bought a End Stop switch and placed it to the side of my Rapide Lite.


    I bought this: http://bit.ly/145eNPy
    Its a microswitch connected through COM and NC. This means, that when the switch is made it cuts the power through the circuit. When i run my X-axis to the max distance of the print bed (~195 mm from the home position) the switches wheel hits the side of the platform on which the printbed is placed - and the switch cuts the power to the printer.

    Since my printer uses Marlin, i havent found a way to use any gcode commands to shut it down. I saw that you can use the M81-command to shut it down, but that didnt work on my printer - so i had to create this.


    You can customize this in Tinkercad:

    This is a great idea, but you can't turn it on if you want.

    I bough a relay to connect to the RaspberryPi and will control from the RPi the power of the printer. Then you can just fire an on or off status to the printer.

    A guide how to control the printers ATX-supply using Octoprint! The creator of Octoprint is amazing. How convenient is that!
    https://github.com/foosel/OctoPrint/...sing-OctoPrint

    I will now rewire the printer because of this and add the PSU Controls to the Octoprint UI using his code.

    Btw, i got the printer on the web!

    Jonatan I only ordered the RPi myself yesterday after your post
    But I already printed the case hehehe
    So when I get the printer completely controlled by the Pi, even its on/off and led lights for the camera, I will post the photos and details.
    I am drawing the bedplate support for the camera and after test it I will share the model if it is good enough.

    Wohoo a support for the camera, this is getting way too exciting already!

    On the RPi+ATX thing, I'm assuming the firmware on the Rapide do have power controls for this embeded?

    My plan is not to use the firmware power controls because it means that the power supply needs to be permanently turned on to keep the circuit board operational.
    What I don't like much is the loud noise of the power supply's fan.

    I am going to use this:

    One relay for printer power and the other for LED lights.
