Is it normal for the z-motor to make any noise when idle? Noticed when it's quiet in the shop, the z-motor is giving a high-pitched noise, when it's just powered on, not moving though. Wondering if my z is acting up, possibly causing the ridges I noticed. Ridges are worst after z-move for 1/2" or so along the y-axis, raster cutting along the x axis. Earlier post showed the ridges.
