Hello, I've been working on a metal additive manufacturing machine for a while now and I'm still trying to figure out if there are any real drawbacks to using a chain drive to turn 4 screws. My weight capacity on the bed is around 350 lb which is why I was considering using a chain opposed to a belt. I'm not sure of the limitations of using chain and now this might affect accuracies.
Any advice or information is greatly appreciated.
