ENDER 5 (pro) electronics mounting plate for Raspberry Pi
This mounting plate is designed to be placed inside the electronics case of an Creality Ender 5.
It should hook under the power switch on the left side of the case and has holes to be screwed onto the side of the Meanwell/Landy-PSU using M4 Screws.
It a direct remix but I changed the base plate to hold a shelly which can be powered directly from the printers 24V PSU.
Then I added a "one shot" service to the pi which depends on network and will be triggered on poweroff (shutdown, halt) and just sends an http get request to the shelly to trigger a delayed (10-20 seconds) relay power off. The pi can be powered off via octopi's main menu or gcode (M118 //action:poweroff) interpreted by the octoprint plugin called "action commands". This gcode can then be added to the end gcode segment by the slicer (e.g. Cura) or send to the pi using the ender 5 menu by adding the following lines to the marlin configuration (Configuration_adv.h):
#define CUSTOM_USER_MENUS
#if ENABLED(CUSTOM_USER_MENUS)
#define CUSTOM_USER_MENU_TITLE "Octoprint"
#define USER_DESC_1 "Power Off"
#define USER_GCODE_1 "M118 //action:poweroff"
#define HOST_ACTION_COMMANDS
...
#endif
The configuration produces the following menu:
My installation looks like this:
The model looks like this:
If (and only if) anybody is interested in my version, I would prepare a "thing" with a full description and my remixed stl file...
The shelly is rated for 16A while the Ender 5 PSU is putting out about 14.6A at 24V max... So we are safe to use this kind of relay for the DC side. The cables I used have a diameter of 0.75mm²... which is only just fine...
