Non-trivial kinematics is when moving one axis causes another axis to move. We call these "serial links" For example, if you were to mount one rotary axis "B" cross-wise on another rotary axis "A" such that moving "A" redefines where "B" is pointing to. This is common with robots but uncommon wi

Greetings all; I am about to install this rebuilt rotary drive on my 6040 mill, aligned to rotate stuff on the Y axis, which is the long axis on a 6040. Out of the alphabet of ABCUVW, which is the proper axis to call it? It will for the next job, be turning a 2"x2"x18" on center of its 2x2 end
