I was just curious if anybody else had a similiar problem. During a part change, (program ended M30, waiting for cycle start) I noticed that the servos (I'm assuming) tend to make a a noise that is soft at first then increases the longer it sits. If I go into MDI or just move one of the axis it goes away. Granted, I have a very quiet shop at night so it probably would not be noticed in the standard work environment, but I don't recall it did when I bought it...about (3) years ago. Not a big deal, just want to make sure I'm not doing something wrong or making it worse buy ignoring it. Thanks
