Creality Ender 3 bed leveling gcode

As many of you know, the Ender 3 doesn't come with a built in Bed Leveling program. So I wrote this one to do a simple double round of checks around the bed with pauses to adjust the bed screws. If you want a single pass, just edit the file in Notepad or other text only software and remove the lines I've indicated in the comments. I have it go around twice because I've found with the 4 leveling screws that you often need the second pass to fine tune it.

There is no bed heating or extrusion with this gcode, which saves a lot of time compared to a couple I tried that other folks had.

I also made sure to move the extruder up and out of the way at the end.

Give it a like/thumbs up if you find it useful.
