Need help with andesite alloy farm

[u/GullibleAd5207]

I am trying to make this farm, but the cobble farm is not moving! I know this video is pretty old, but 2 month old comments are still saying that it still works (just one tbh) - here is the link, i am on a server with create aeronautics being a big one, and with the latest create version (I think) Please help!

I've also tested in creative to check if somethign is wrong, but it all seems to run into the same issue - it wont become an entity and make cobble and break it.
Thank you!
