Hello,

I got my first machine recently and I've been trying to figure out what has been causing the z-axis to be fairly noisy. Like it's catching and jumping .005" at a time. Here's a video mainly for the noise.

I've made sure that it has been thoroughly lubricated and I'm fairly certain that it is coming from the spindle shaft (don't know the proper term for it) moving up and down and not the ball screw.

Any ideas on how to fix this problem or will it work it's self out with time?

Thanks,
