I would like to add following end g-code to all my g-code files automatically. This code should allow my creality ender-3 pro to switch itself off after the nozzle is cooled to 40 deg. This is done with some modifications to the machine such as a switch, relay and microswitch. See https://www.thingiverse.com/thing:3744808 Where can I add this end code? In Preferences - Ender-3 - Machine settings the tab for End G-code is empty and can not be modified.
