A print to assist with leveling your bed.

Directions

1. Open in customizer and set layerHeight and layerWidth to match your current setup.
2. Set distanceFromCenter to a number around 20% of your print bed size. On a 200x200mm bed, use around 40.
3. Adjust the other settings if you wish.
4. Create the STL and download it, and prepare it for printing.
5. Check that the printer is ready and build platform is mostly level.
6. Print the test you created.
7. Examine the result and adjust the level. See the tips below.
8. If the print was perfect, print your model. Otherwise go back to step 6.

Tips

• Issues which could mean the bed is too low:
  • Gaps in the first layer.
  • Corners or edges peeling up.
  • Complete failure to stick to bed.
• Issues which could mean the bed is too high:
  • No filament extruded/missing peices.
  • Layer is not smooth/has bumps and lines.
  • Leaves a trail of filament between pieces.
• Also compare the thickness of the pieces from side to side and corner to corner. You want them to be as close as possible.
• Remember that when you adjust a screw, it changes the whole bed. Make sure to counter balance as you adjust. For example, if one side is high and the opposite side is perfect, I will adjust the high side down and then the opposite side up about 1/2 the amount I adjusted the high side.
• Always use small adjustments. If you have a long print ahead of you, it is worth getting the leveling perfect.
• Note down on your printer which way to adjust your screws. Trust me, it's worth the tiny effort
• Make sure everything else is set before you try to level. Leveling should be the last step before a print.
