Audio quality on phones is not the best but it definitely does sound gritty.

Like you said, I may as well get them to send me another but in the meantime it seems sensible to explore other options. This machine was a bit of a headache on the shoot. It was really good, software worked well, the camera moves I was able to accomplish were great but the vibrations ruined shots. Everything would look fine until I got into the edit and noticed these violent vibrations which would cause the lettering on the pen we were shooting to almost buzz for a moment.

In other words, still really interested in what you can put together Dean.

Shall I ask them to send another ball screw and ball nut? From what I understand it's hard to put those two elements together so I'd be a little concerned if I needed to put the new ball screw on the old ball nut.
