Hello there,
I'm trying to abuse an old and partly defective MAC 250 moving head as a dmx controlled pan- and tilt-motor, holding a ~ 1.5 x 1.5 meters sized and ~ 4.5 kilos heavy reflective surface. However, I noticed that it seems to have kind of a 'safety clutch' or torque limiter feature in order to not hurt people who like to reach for the moving head while it is moving around. As I would need the pan and tilt stepper motors to be more powerful than they are due to the restriction of the 'safety clutch' – in case there actually is such a thing within the MAC 250's at all – I would love to know if it is possible to somehow bypass or remove this clutch while keeping the rest of the functionality. As I have basically no idea about how the mechanical side of the moving head is designed, I wanted to at least give it a try and ask about that before it is being taken apart and cannibalized. In that same sense: Any suggestions on how to keep the pan and tilt movement from doing its 'safety clutch' thing as soon as you hold down the yoke with a fingertip?
That would be greatly appreciated!
Best,
