    Adding a slaved X axis

    Hi all,
    I've built a gantry router which is up and running and i want to improve it by adding another ballscrew and motor etc. slaved to the existing x axis.
    The problem i've got is that the existing x axis (from ebay ) seems to be an odd size ( 18x8 ) and i cant find the equivalent new.
    Can my new axis be a different diameter and pitch and still be slaved to the existing one ?
    I almost dont want a reply as i suspect it will be bad news !
    Cheers,
    Nick

    No, the two axis need to be identical, with identical settings.

    i know you may not like this but you could swap out the thread for a chain or pully.
    with two chains or pully, one on either side.

    i've heard they are an improvement.
