3 * RM1610 ballscrews, 780mm & 660mm

So what's the rationale for using pulleys to drive a ballscrew rather than connecting the stepper motor directly inline via a flexible coupling?

Couple reasons really.
Easy to gear for extra speed or resolution/torque. It also helps reduce resonance that affects the motors.

Many thanks - I hadn't considered the potential flexibility offered by interchangeable gearing.

That raises the question: What brand/source of pulleys/belts are currently in fashion/recommended?

{Presumably, belt manufacturers/suppliers provide tensioning guidance?}


Thanks
