    I have been using my LED Smart Controller to print with a full sized SD card. The print works as intended, but though the extruder returns to 0 degrees when the print is finished, the bed remains at the temperature it was at during the print. That means if I print through the SD card while I'm away from the printer, when it finishes it keeps heating the bed, running electricity unnecessarily. As far as I can tell from the settings, I have selected the option that says "Return to 0 when finished" or something to that effect. I'm exporting the GCode fine, so why is the bed not returning to 0 degrees? Do I need to add a line of GCode before exporting to the SD card?

    Add this to the ENDING GCODE section of your slicer:

    M104 S0 ; make sure the extuder is turned off.
    M140 S0 ; make sure the bed is turned off.
    M84 ; shut down motors.

    If your bed remains at the same print temp then you have a problem, but if it simply is just not going to 0, it probably won't unless your room temp is 0 degrees

    You might also consider raising the nozzle 5 mm then moving the nozzle to one side and then front or back. Here is a copy of what I do in end gcode:
    Code:
    G1 E-5 F300  ;Retract the filament to release some of the pressure
M104 S0  ;Turn off extruder
M140 S0  ;Turn off bed
G1 Z5  ;Raise nozzle up
G1 X10 Y220  ;Move bed over & forward
M84  ;Disable motors
M117 Print Complete  ;Display message on LCD
