This is a customizable test pattern for testing and calibrating mesh bed leveling.

There are quite a few test patterns out there already, but I found most to be too complex and many are just static STL files that aren't customizable. So, I created this.

Download OpenSCAD and use it to open the SCAD file.

Mesh Settings

• Test Circle Radius: this is the size of the test circles
• Mesh Points: Select the mesh size. If you use a different size you can just enter it directly in the OpenSCAD editor

Printer Settings

• Layer Height: the height of the test circles, this should match your printing layer height
• Bed Width & Length: this should be set to the bed width and length you have configured in your slicer
• X & Y Inset: this is how much distance there is between the edge of the bed and the center of the test patterns. This should be at least twice the value of Test Circle Radius
