Ok so, im learning so, If I ask stupid questions, they are for reasons that, possibly I cant really answer.

I know that yourr Gcode wont be exactly the same as mine only because my printer and process is going to be different. As far as the auto bed level, i have one mounted to the side of the extruder body. it does extend to find the relative position of the bed to the nozzle. Like an idiot, I copied your code into S3d and, proceeded to start a test rrun, no filament to be extruded only because I manually set the temps to stay at room temp.

Silly me... is there a command that needs to be entered to have the Z probe extend? Orr is this assumed and automatically done? my z probe did not extend and the print head crashed into the build surface. LOL
