(I have tried four different thread titles already but its sorta impossible to try and summarize the issue in a title and have it sound logical).
This is a natural extension of the issues i had in this Rigging Mechanical Objects/Objects with Rigid Parts only Designed to Rotate one direction
Currently im trying to Rig a Wooden puppet arm, Being somewhat mechanical in nature the arm lacks proper ball joints per say and instead, similar to a mechanical arm it has individual components designed to function to only rotate on certain Axises,
Image to sorta visualize it.
Now I have managed to get a a IK Rig that works somewhat for this, it has everything constrained the right way, none of the objects move to contradict the mechanical joints, but there is one issue im still running into. I cant set a pole target without the thing breaking, and as such i cant easily or really at all control the direction the elbows are going to point.
This was my Rig, the second upper arm bone allow a tiny amount of control in the elbow direction when i rotate said upper arm, but its hardly any control and the Rig snaps alot aswell.

I also have another Rig, provided by the eternally helpful https://blenderartists.org/u/ajcdfin . There one is far better with less snapping and less bones, and while it has a bit more control of the elbow by dragging the IK controller up the arm and what not, its still not as elegant as having a Pole Target.

So the Question i wanted to is between these two rigs, or perhaps another im not familiar with, is their anyway to have a Constrained Robotic IK Rig like these and still be able to use Poles and Pole Targets correctly?
