Volt tilt bump on button press

[Andrew Brinkhaus]

Hey all, been using my new Volt recently, absolutely love it. I do have an issue though, if I tilt to a specific frame, and then press the volt button, the tilt motor bumps or 'knocks' upwards slightly, which disturbs the frame. It seems that if I press the button and then only tilt a small amount before pressing it again it doesn't always bump. But if I go from looking straight forward (0° tilt) to 45° and press the button, it bumps before settling back to the position where I pressed the button. 

Using on an M-1, double and triple checked dynamic and neutral balance, Volt is on firmware 1.7. Any insights?

There is an instructional video on the Tiffen website as to how best to avoid the bump. I still prefer to use it in "Sticky" mode where it locks in perfectly with no bump wherever I leave it.

Thanks Lawrence, so you've experienced this as well? I've watched the videos, other than the 'click as you go' method I didn't see anything that addressed this particular issue but maybe I missed it.

One of the changes to the firmware that Steve Wagner made to v1.7 was to briefly switch into sticky mode before returning to normal mode. I suggested that because sticky mode dampened problems with timing when releasing the tilt pressure after hitting the button. What I have found now is that if there is a "bump" up after hitting the button it is likely caused by a very slight error in static balance - the sled being slightly back heavy ; if there is a bump down, the reverse is true. I test it and make a slight fore/aft adjustment if there is a bump...

I've found that pressing the button literally .2 seconds before your hand releases pressure off gimbal handle, it locks off pretty nice. Kinda tricky to get the timing down, but once you get it it's kind of muscle memory

Andrew, and Adam, and anyone else...

2 questions:

1 - have you tested changing fore/aft balance as I suggested above and then trying to hit the button after a tilt?  I would love to know if this is generally true that a slight error in fore/aft balance contributes to this “bump” or if it is just on my Volt.
2 - I have been thinking about increasing the length of time the Volt stays in sticky mode after hitting the button in normal mode.  It is a very short time now.  That might remove the .2 second anticipation you are using.  Any thoughts?
