KP3 Positioner question?

  • Hi all,

    I have a bit of a strange issue so was hoping if someone could shed some light to fix the issue I have with a KP3-H2H external axis Positioner.


    The positioner has 3 H2H axis with a self-aligning and length compensating counterbalance with a compensating factor of +/-5mm and +/-0.5° mechanically.


    We have designed our fixtures to suit the application that can only tolerate +/-2mm now recently we have a very strong shift in the mechanical movement of the shaft and can confirm the shaft floats anywhere between 4-6mm and stuffs us to reteach every point by an offset on Y (world coordinates). So my question is how do we lock the shaft in place without length compensation? Why are positioned made with such high tolerances?


    Any help appreciated.
