Just purchased this mill and have no experience with Tree or Dynapath 40m control. I do have the manuals which are helpful and I’m kind of learning things as I go. I’ve found that when I jog the X axis in fast or rapid mode I’m getting a rather annoying high pitched squeal. I’m concerned it may be due to a dry ball nut. This machine of course has the automatic lube system but I don’t know of any way to confirm if the nut is receiving lube? Any ideas what could be causing the noise and what I can check? I thought it may also be the screw end bearings but haven’t had time to investigate.

The spindle likewise is making a rattle noise occasionally when decelerating. I’m guessing bearings are likely the culprit there.

Thanks for any insight offered!
