Flashforge finder bed level checker

When the output was made to the maximum possible size, a contraction occurred at a specific location.

The printer says that level is right, but it didn’t fit.

Contraction occurred in areas where bed was not closely attached.

So I made it.

140mm in width, 140mm in length, and 0.2mm in height.

It is the size that can output 1 layer to the maximum allowable range of my printer.

Whether or not the level is right can be seen from the output.

The areas where bed is not closely attached are different in density.
