Rot table with non-parallel axes

Hello,
Trying to create a mechanism of a rotary table that has a smaller satellite rotary table on top of it. If I set the axis of both joints perfectly parallel to the world csys the mechanism creates without any trouble. If I set the axis for each joint as it is in actual machine, slightly off from perfectly parallel, Robot studio crashes when I try to compile the mechanism. This happens on RS 5.14.03 and 5.15.00.01. What exactly is the limitation here?

    Hi Jeff,

    What you are trying to do should work. If you mail me (anders.spaak@se.abb.com) your geometries, I can take a look at it.

    Thanks Anders. I will send them on Monday when I return to work. I have narrowed the problem down to a situation where both axes in the mechanism are nearly parallel to each other, but not exactly, and are nearly parallel to one of the world axes, but not exactly. I can compile a mechanism where both axes in the mechanism are parallel to each other but slightly off from world without error. Luckily this is good enough for my application.

    Thanks,
    Jeff
