You need to choose one of the valid kinematics types. As far as I know
there is no documentation on them, and you have to guess.

A kinematics routine defines a translation from joint positions to
cartesian location, and the inverse transformation. Both pieces of
code have to match, so that if you pass the same numbers through one
way, then back through the other, you should get exactly the same
numbers back.
This can mean having to find alternative formulations of the equations
if floating point arithmetic gives subtly different answers, as that
will lead to the joints drifting.

This isn't a problem with Gantrykins, there is no maths in there.

The idea that there is no such thing as objective truth is, quite simply, wrong.
