I sometimes use cones of regular thread (not serger) but I let it feed from the side as it is cross wound. In cross wound threads, it needs to feed so the thread curls off the top of the cone. You need to put it in a cup behind the machine, put it side ways as I do or buy a thread adaptor.
Serger thread I have found has imperfections that will prevent it from feeding smoothly through a sewing machine.
