This is a gcode for the Creality CR 10 Mini.
Since it uses coordinates specifically for the CR 10 Mini glass heat bed, use on other printers might cause problems.
The file to use is the Bed_Leveling.gcode, the .stl file is just there in order to let me upload the gcode.
While traveling across the heat bed the hot end elevates a bit to let you slide in a piece of printer paper (or whatever you use to measure the correct height).
It stops above each of the heat bed screws for measuring.
Check the height and adjust accordingly, then press the button on the controller box to proceed to the next point.
Put the file on your sd-card and choose "Print from SD card" when you want to use it.
(Works like an ordinary print)
It does not heat the bed or nozzle.
Requires no printer settings at all.
