Hi,
Having a quick look at this, and I manage to repro it here.
What causes the deformer to move when doing fk-ik blend is the
expression that is driving the position of (chain_C0_1_loc etc..
assuming that the bone will translate) is blending between the local
position of ik bone that has no neutral pose againts the FK chain
controller position that has neutral pose.
To fix this, you could try to set neutral translation on the bones of
the IK chain. (chain_C0_chain_0_bone etc.. when name is default)
considering the deformer parent also has the same neutral pose on it.
The other thing that worth mentioning is that the FK chain doesn't seems
to align to the IK chain by default, but you should be able to match
the rotation easily.
Cheers,
edy

OK, now it seems to be an issue with the chain itself. In a brand new
scene I created a chain with 3 guide elements. I unhide the deformers
group to see the deformers, and when I play with IK/FK blend value, the
deformer seems to move along its local X axis. At blending of 1 the
deformer is double the distance from its parent than originally
Anyone could make me a test?

I’m creating a rig with Gear, but when I use Chain (simple), the
compiled rig has a strange IK behavior. It looks like that the IK chain
is scaled compared to the FK. It is visible when I switch the blending
to IK and the deformers start to offset from their original position…
