My CNC router (http://www.gldpages.com/CNCRouter.htm) has 5/8 acme lead screws with acetel anti backlash nuts. The X axis squawks on rapid moves, and sets up a vibration in the machine. My rapids are 60ipm. Haven't ever noticed any indication of lost steps it's just annoying. It's done that ever since I built the machine in 2004. I've used silicone spray but that only last a few minutes. Really shouldn't have to use any lube, the Y axis has never made any sounds.
Suggestions welcome????
