Bucket looks empty to me

It uses the lava bucket then is meant to put the empty bucket into the thing above but isn't I've connected it all properly.

What mode is the mechanical arm on?

If you have it forced round robin then it won't work

I fixed it now thanks

Do you have any idea on how I can take power out of the tank and use it on other machines?
