It has to be a problem with your cabinet hinges or the way you have the cradle installed. Are the cabinet hinges freely moving or are they stiff? They should just flop around and be a PITA when trying to get a heavy machine reinstalled in a cabinet. If they are stiff give them a drop of sewing machine oil.
Remove the cradle completely and loosen the screws on the cradle until they are almost out the whole way, re-tighten them just enough to stay in place when you put the cradle back on the hinge pins. Once the hinge pins are inserted in the cradle there should be no excess hinge pin showing. Tighten the screws and see if it will close.
