im working on a last action hero and need help with the crane cam the crane will move all the way to the vuk where it picks up the ball and the motor continues to run as it should but the crane just stays there on the vuk side and never returns to the ball lock position, i know that the motor only turns one direction what i dont understand is how this cam thing functions cause it just stops like its stuck on something but i cant physically see anything, whats the trick to this? thanks guys!
