Hey Ryan,
you need something like the leveling feet anyway (fortunately they’re included with the QCW frame now) since otherwise you would not be able to get the machine coplanar. As this machine is of gantry-type, which means it has two Y axes with a considerable distance one from the other, you need to adjust it for coplanarity (=absence of twisting, for explanation please see here and here). A twisted machine can only produce twisted workpieces, starting with a twisted wasteboard
