This is a program (gcode) to level your Ender 3 print bed.
Take the Thumbdrive that came with your printer and insert the memory card.
Put it in your computer.
Download this file.
Unzip this download.
In the "files" folder, copy the "LEVELERv2.gcode" file to your Thumbdrive.
Remove the memory card from the Thumbdrive and put it in your printer.
Select "Print from SD" on the printer display, then refresh.
The bed and nozzle will heat up and the program will then start.
The nozzle will go to the front left of you print bed and pause.
Insert a piece of paper such as a post-it note under it and move it around while turning the adjusting knobs underneath until the paper catches slightly.
Press the button to move to the next position and repeat.
The nozzle will move to all four corners and the middle, then all four corners again.
When the program has finished, your printer will cool down and the print head will move to the home position and your bed is now level!
Select a file on your memory card, such as the dog and do a test print.
Press LIKE if I helped you or even give a TIP if I made you really really happy :)
Thanks to Chuck Hellebuyck for the original.
This program will work with all 3D printers that have a print bed of similar size as the Ender 3 or Ender 3 Pro.
