HI, thanks for the response. I cannot locate the buckle switch. I flipped through the Arriflex 35 book and there was nothing called a "buckle switch" in there. There is an inching button but when the camera has power nothing happens when I press it.
The inching knob moves free and smooth when the movement is open or closed.
When the door is open and I flip on the switch. Everything seems to have movement and nothing seems to be getting in the way. I hear no grinding, no scratching, nothing. The belt and inching knob move for a split second then stop.
My initial guess was there wasn't enough amps to run 23.976 but even down at 5fps the same thing happens. The battery has been charging for 12 hours now so I would think that would be enough to get a steady frame rate.
