Doing the final lash inspection on the machine after assembly and I am getting some play in the head stock. I have a dial indicator in the spindle pressed up against the vice baseplate. Checked the play on the X ballscrew by pulling/pushing directly on the screw itself and I get the normal few 10ths of jiggle. However, if I pull/push on the headstock mount casting I get about .0015 of jiggle in both X directions. I have confirmed that all exterior bolts are tight.
Measuring against the ball nut with the indicator on the carriage I get ~.0005 of spring back.
Can someone go and run this test on theirs to see if they get the same results? Is there some internal bolts I need to tighten up to take out this slop?
