This is an auto power off design for the printer after finishing the printing process. Elements used include: 1x SZM-V16-FA-62 Normally Closed Switch https://www.aliexpress.com/item/32705889929.html 1x Connection Socket https://www.aliexpress.com/item/32706948395.html 1x PC Power Cord https://s.click.aliexpress.com/e/rbj1uu7W 1x Set of Printer Parts Some short pieces of wire The most interesting aspect of this mod is that no part of the 3D printer needs to be modified. Simply add this mod and enjoy an auto power off system. When the Z axis reaches the top of the 3D printer, a gcode sends a signal to switch off the motors for a smooth power down. There are two to three seconds between activation of the switch and machine shutdown. Although I have tested this modification and it works perfectly, I am not responsible for any damage that may be caused by this upgrade to your 3D printer or other equipment. Use this modification at your own risk. To make it work, you must add a small piece of gcode in your end code script in the slicer program (slic3r, simplify3D, Cura, Repetier, etc): ;---------------------------------------- ;End GCODE Script M104 S0 ; turn off extruder M140 S0 ; turn off bed M107 ; Turn off fan G91 ; Relative positioning G1 E-3 ; Reduce filament pressure G90 ; Absolute positioning G92 E0 ; Reset extruder position G1 X0 Y200 Z239 ; Get extruder out of the way M84 ; disable motors ;---------------------------------------- Modify the Z value to get the best results in your printer depending on your Z length. The interruptor located next to the power cord connector serves to activate or deactivate the auto power off system, keeping the printer always on or not.
