Gcode for auto shut off?

Hello,

I was wondering if there is a way to have the printer auto shut off the heated bed when finished with a print; the hot end shuts off but the bed does not. Would I need to add custom gcode into slic3r? I once tried putting an "M" code before but It did not do anything. Sorry if this has been addressed before, I did search this forum prior to me asking but did not find anything.

Thanks

M140 S0

should work I guess.

Thanks. I'll give that a try.

Hey DrMacZed, which printer do you have?

I have a 8inch i3v that does not have a heating bed relay. Mine has always shut both the hot end and bed down after printing.

I have an i3v 8" and a Pegasus 10" both with heated bed relay.

This is my end gcode for shutting everything down-

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