The board is mounted where it's shown in all the documentation and assembly videos I've seen of this thing. I don't understand how things should all of a sudden be different now.

The only thing I did to it was make a new bracket to hold the RAMPS. That positioned it perhaps 3-5 millimeters higher than where it originally sat. The only thing it got "closer" to was the heatbed. I might could try shielding that with a piece of foil. I insulated it with a thick piece of cardboard so I do have a nice surface to attach the foil to.
