Because aluminum structure which supports the board misconstrued the bend, so I crack the aluminum to make machine shop, bending the back and clean the board ready to bring a return.
The aluminum frame that supports the board to bend. I remove the aluminum frame to machine. The shop has a curved track. Clean and ready to be returned to the board.
