Turn off printer power using end script

This project will enable you to use an entry in the end script to remove mains power from the printer when the print is completed.

I created this for my Geeetech A10 using a GT2560_v3 board running marlin 2.0 Bug_Fix but should work with many other printers that run marlin and have a free ADC output pin that you can use.

The hardware I used is a BIGTREETECH Relay V1.2 Module Power Monitoring Module For SKR V1.4 PRO E3 current cost £10 on ebay in June 2020. A single push to make switch to act as the reset button, I printed a housing for it and will include the stls but its part of the fun to design your own .

Two Marlin files require editing, as I said this was done on a GT2560_v3 board, you will have to locate another pin if using a different board, but here are my changes.
In the pins_GT2560_V3.h file you have to Rem the command that previously used the pin.

Edit the following lines to disable runout sensor 2 by adding //
//#ifndef FIL_RUNOUT2_PIN
//#define FIL_RUNOUT
