'Machine Width' is the distance between the outside diameters of the left and right sprockets (it might not be mathematically ideal, but it's close enough and most practical).

If using belts, machine.motors.mmPerRev=belt pitch x number of sprockets.

Aye, I think mmPerRev in this case would be the circumference of "Sprocket Pitch Circle". This diagram shows a sprocket with 22 teeth (I think), so belt tooth pitch x 22.

A less mathematical way is to count out 22 teeth on the belt and then measure the length.
