I set everything up right but it isn't working. The beginning location is the opposite of the locator position for some reason (only in the animation tab) and I've alreafy tried remaking it and deleting the other ik stuff (which had the same problem).

Not an IK expert but have you tried looking at the following guide?

# radiant minnow The model follows all of those steps

I think your null Object is nested somewhere under the root of the arm you're moving?

The second step of the tutorial says a "parent bone of the chain". That means the null object should be on the same level as the group "RootL" or higher, not under it.
Else, as you animate with IK the arm, the null object itself will be moved by the groups it animated, it feesd on itself. I believe that is why Blockbench only moves the end group in the chain in that case, the movement for the other bones is impossible to compute.

I say proably put the null object directly under "Securiton".

Do you mind sending your model then? I can try on my end

Scratch what I said about the last group in the chain being the only animated one, I found the issue

#

Although you do have to put the null object at the same nesting level or higher than the root group of the chain, the problem was the pivot points. They were completly off
