I have seen this done before, but this normally involves more money and because the motor/gearing that is associated to this type is moving with the ball nut, the moving mass is higher.

Didnt think of that . Ist the main problem in this case the actual torque needed to spin the screw? Although the extra weight wouldnt be ideal surley it is a lesser evil ? wouldnt it be possilble to also use a smaller screw which would make it cheaper?

Sorry to hijack your tread :naughty:

I have customers who uses this method to get faster motion, but normally would use a servo motor and specific gearing that is only for this type of application.
Unless you get the parts on ebay, it will cost a few hundred just for the gearing.
Also fixing both ends of the ball screw offer similar results (Within about 25%)
