Schott, Are you insuring the the bit shaft is not inserted to where the cove begins the bit. This certainly allows for slippage and the collet will not tighten onto the shaft securely allowing the bit to fall out even. Leave the shaft protruding about 1/16-1/8 ’ at least and tighten securly. if you have sone scrap test that for a few cuts with either router you are most comfortable with. See if this cures your problem. MLCS bits are quality bits and probably not your culprit. Russell
