Turning off bed and Extruder at end of print

Hi folks, I want to run my Mendel 90 overnight but want it to all shut down at the end of a print.
How do I set up in Pronterface to turn the bed and Extruder off when it finishes?
Thanks
Steve

Ive only been at this for a month but I think M1 could be put in your end G-code. M1 = sleep. It turns off all motors and heaters.

you would do it with gcode.

something like the following as your final code.

M104 S0 ; turn off temperature
M140 S0 ; turn off bed
M84 ; disable motors


if you use an atx supply you could also add M81 to turn of the power supply.

Bear with me .... How do I actualy do this.
If I load my file onto Pronterface using Kisl3r do I just type the code at the end?
Or what else do I do?

Kisslicer had a postfix section in the prt G-code tab. Any code you put there is added at the end of the generated g-code

Thanks folks
