g code

hello

for the extruder and the bed heaters at the same time I must put everything in slic3r / printer setting / custon g-code?

at the end of work I would like the bed back to 0 that is to say all down with the bed and the extruder stops complement to heat.

thank you

my actuel code

start

G28 ; home all axes

G1 Z5 F5000 ; lift nozzle

end

M104 S0 ; turn off temperature

G28 X0 ; home X axis

M84 ; disable motors

Disable bed

M140 S0

<blockquote rel="Repetier">Disable bed

M140 S0

this code end or start?

sorry I am novice!

Wherever you want to disable the bed, so normally at the end. Normally slicer will add these codes on it's own.
