Universal Auto-Power-Off (Octoprint controlled), here for Monoprice Select Mini

UPDATE V3 includes "Octoprint PlugIn Temperature Failsafe" support. UPDATE V2 documentation is now available in English, or at least that's what I call English. UPDATE V2 of documentation confirms PSUControl compatibility with CURA 4.4.1. This Auto-Power-Off solution should work for all 3D printers controlled by Octoprint using the PSUControl PlugIn: https://plugins.octoprint.org/plugins/psucontrol/. It is based on this relay switch: https://www.thingiverse.com/thing:3927180. The attached PDF documentation is written in German but I will add an English version by the end of the first week of February 2020. Meanwhile, you can check if you can translate or follow the instructions following the embedded links and pictures. You need Octoprint on a Raspberry Pi to make this work. I used my version on a Monoprice Select Mini but the only specific thing is the mounting plate for all components (RPi and relay enclosure) on the back of the printer. If you like to use the same RPi case, check out: https://www.thingiverse.com/thing:922740. Please follow the instruction attached here as a PDF file.
