    i don't know that anything other than a harmonic drive can offer as much torque with as little backlash in the same volume.

    a 570 oz-in stepper coupled to a 50:1 harmonic drive would be overkill unless the harmonic drive is the size of a phone book.

    I'm not really looking to "high speed machine" with the thing - just worried that if I run a little fast by accident that I'll destroy it. Looking like the harmonic will be in the budget - Eldon, what gear ratio would you suggest?

    I'm also thinking of using the 570s for everything but the Z, mostly to just keep things simple...
