<p>Hi</p><p>I design a Mechanical “auto” power off for the Anycubic Kobra. The project needs a little of Electrical knowledge to know how to connect the cables. The cover Picture is my prototype, on the download files is one that I designed afterwards and tested.&nbsp;</p><blockquote><p><i>Maybe the button that you buy have some plastic holders on the sided, mine had too and I cut it off.&nbsp;</i></p></blockquote><p><strong>Print data:</strong></p><ul><li>Quality 0,3</li><li>Infill 45%</li><li>ABS/PLA</li><li>50mm/s</li></ul><p>I used<i> <strong>one pole </strong></i>switch with back light, he can be installed on the blue or brown cable <strong>BEFORE the DC power supply</strong> using the cables coming from the main switch on the side of the machine.&nbsp;</p><p>You will need to open the lid under the printer in order to install the cables. That can be easily done. <strong>PLEASE WORK WITH THE MACHINE DISCONNECT FROM THE CURRENT. </strong>After installing, you can check if the buttons cut off the main switch from the machine. I would advise to disconect the DC power supply (Red and Black cables) while testing too.&nbsp;</p><p>You will also need to change your end codes. I use this sequence at the end.<strong> </strong><i><strong>Do not copy what is in bracket.&nbsp;</strong></i></p><p>G28 X0 - (The printer head will go to the side)</p><p>G4 S300; Machine waits 5 minutes</p><p>G28 Y-5 (The bed will retracts further as normal)</p><p>M84</p><p>When the machine starts, she goes a little further in the Y axis, that is why the button hast to be placed in position after the machine starts printing. When The machine goes back to 0 she will not press the button. In that way you can still use the entire surface of your bed.&nbsp;</p><figure class="media"><oembed url="https://youtu.be/gV8N-6Q-hQ8"></oembed></figure><p>&nbsp;</p>
