Material is not level or is warped

Check if material is level

• Lay your material on a flat surface and press down on each corner to see if it wobbles.

• Alternatively you can measure the material thickness (using a pair of calipers) on each corner or side.

• If the material is wood, and you have a planer, you can even it out. Make sure to re-measure the material thickness
