Question HD Solver Pivot Problem

Hi People,

I'm working on a 4 piece robot leg - with hip/upper leg, knee, lower leg and ankle.

The knee is on a 25 degree angle, and I have set its pivot so that the Z axis is also 25 degrees. The problem is that when I try to set the Z axis limits on the knee in the IK rollout, the solver is using the world Z axis rather than the knees local Z axis (set at 25 degrees). I checked the bone position, and I'm confident its in the right place. I changed the reference coordinate system to local just to see if that would change anything, but nothing seems to work. Turning rotational joint boxes on and off (active on/off), doesn't affect anything either.

What am I doing wrong?

Thanks for any help!
