Its just the left Y axis and worse at slower jog speeds. I thought it was the ballscrew so I replaced the ball screw bearing/ rod as an assembly. Exchange of parts was really straight and easy, all looked good. After replacement the noise is even more pronounced. I’ve never uploaded a video here, so hopefully it uploaded just fine…Working with support, but wanted to share and pull from the crowd as well.
After working with support, it was determined that the M2 port signal was causing the noise, using the same motor cable and swapping between the M1 and M2 ports, the noise followed the port. Driving the screws of each Y axis, individually, on the M1 port, with the same cable sounds as good as new. I have to say the level of support, even on a weekend is pretty amazing.
