This box contains a Raspberry Pi running the fabulous OctoPrint / OctoPi, a 5 V power supply and an SSR. It allows you to remotely turn on and off your attached 3D printer, either by using the web interface, by sending G-Code or with a custom system command, which is needed to use the feature through the Telegram plugin. The two hardware buttons are used to power on/off the printer or send a shutdown command to properly power off the Pi.

Next to the hardware setup you will need to install three additional plugins:

• OctoPrint-Enclosure
• PSU Controls
• System Command Editor

All are available in the Octoprint Repository.

SAFETY WARNING: This build works with mains voltage which is dangerous and potentially lethal. Only attempt this build if you know what you are doing. I am no electrician, it's all at your own risk!

HINT: The thumbnail for the PDF schematic somehow does not work with "Show Original". I therefore included a PNG version for quick viewing. Of course you can always download the PDF from the files section for best quality.
