Hi, i tried your code but after Auto bed-level (BL-Touch) the
M104; Set Extruder temperatur will stay furter at 160° and not at the temperature definded in the slicer

Fixed: the problem was i used it in "Creality Slicer" the original slicer wich come out with my Ender 3 Pro.
With "Ultimaker Cura" it works fine - thx.

sorry about the necro, but this gcode works, thanks! no more dripping in the center of the bed or dragging the nozzle across the bed.

hi, for some reason after finnishing the bed was still being heated, before the line M84 ; Disable stepper motors, you may need to add these:
M106 S0 ; turn off cooling fan
M104 S0 ; turn off extruder
M140 S0 ; turn off bed
