Ender 3 Pro Bed Level Test + Calibration Wizard

# This is the *one file* I keep on my local SD card on my Ender 3 Pro to quickly and easily calibrate and validate the print bed level for a critical job.

This GCODE will bring your extruder to the home position, and wait for you to level the bed with a piece of paper. (You should feel very slight friction between the bed, paper, and extruder tip - and it should be able to slide without too much difficulty.)

Once calibrating the first corner, you tap on your Ender 3 Pro console button, it will proceed to do the other three corners. This will happen on all four corners three times. (Please note: each time you tweak a corner it slightly affects the others, hence your last round of calibration should ideally have no changes.)

The printer will then do a test print to help you verify the bed is a) level and b) flat. (Please note: this GCODE uses temperatures specifically for PLA - 210/60 - so modify accordingly for other filament types.)
