Well mine had no problem at all, there is at least 5 mm space all around in the home position, after all I designed it that way. On reason may be that Wanhao changed the position of their limit switches or they have less space in the top frame. Now there are those white plastic sleeves which extend outward of the carriers. They are responsible for activating the switches. If you now move the printhead by hand until it reaches the physical limit, you can see how much space is left between the switch and the white thing. If it's like 1mm try adding O-Rings. I have a row of them on my Y-axis because of the bondtech extruder. But I installed that after the fanmount so there should actually be enough space.
