Doing the Crane arm rigging exercise near the end, my Close bone was causing issues. The action constraints on the clamps were working fine, but when moving the CTRL bone the Close bone was moving weirdly and activating the animation.
I thought to ask someone for help, but I instead went into debugging mode.
I looked at global/local space of the bones, relations and constraints.
First I tried to figure what the Close bone was doing when moving the parent.
So I added a copy transforms constraint but that was overriding the limit location constraint. (And I know that Wayne didn't add such a constraint, but I wanted to solve it by trying to fix it myself)
Add I remembered that the control widget was made to point at a certain direction when moving the CTRL bone.
I removed the Clone bone relationship to the CTRL bone and parented it to the widget control instead.
Problem fixed😁💪
Man it feels great😁.
Like when first starting to code and you spend half a day trying to fix a bug and quitting for the day. Then finding out after 5 minutes the next dag that it was a typo (a lowercase letter that should have been uppercase🤪🫣)
