Hello, everyone. In a middle of shooting C-Force mini motor lost control of focus and asked for callibrating. We tryed to callibrate it, but it didn't goes on. Only yellow light blinking and nothing else. I guess motor do not recognize the WCU-4 at all, because gear was freelly to spin by hand, and motor had no pressure on it. Pls help! How can we solve that problem? Does anyone ran into this?
