| Video Discription | Octoprint can make 3D printing so much better! In this video I have five more great plugins to make your experience more efficient and safer. If using a Raspberry Pi with Octoprint to control the printer’s power supply via relay, we can add a layer of redundancy to cut power in the event of an unplanned and potentially dangerous scenario. This video shows the mod on an Ender 3, but it will work with any almost 3D printer. Important note: set your failsafe max just UNDER the maxtemp in the firmware. If maxtemp is triggered first, the printer will disconnect and Octoprint can't read the temps to trigger the warning. Disclaimer: Just like enabling safety features in Marlin firmware, by completing the steps in this video you can make your 3D printer safer, but never foolproof. Treat it with respect and leave it unattended at your own risk. The relay rating is important. It is generally better to switch the AC live wire rather than the DC 24V+ output as it draws less current. If you still want to switch the DC output wire, make sure the rated power of the relay exceeds the power of the printer. Power = Voltage x Current. For example: Ender 3 PSU supplies 350W. A relay that says 10A x 30V (300W) would be slightly under rated and a safer choice would be 15A x 30A (450W). Simply multiply the V and A rating on the relay to W (power) and make sure this is comfortably above the rated power of your PSU. Thank you to the developers of the Octoprint and the plugins below.
