How to check if your top surfaces are printing properly with this test print?

• Check to see if there are any gaps in the top surface
• Look at the dome and see if it was printed properly
• Look at the slope and make shore there are no pockets or rips in the slope
• Make shore that the infill inside the rectangle doesn't penetrate the top surface 

If any of these things happen increase the top layers by an increment of 1 until it stops happening and looks like a perfect print.

Enjoy
