I finally figured out how to change that Box Transport Mechanism from my previous post into a Linkage mechanism that works. All I needed to do was get rid of one of the links and then add a link to do the same thing using connectors that are already there. I just needed a connection from B to G to make it work. Then the link that I removed from the original wasn’t needed. Look at the video and it should become clear what I did. If it’s not clear, look for the yellow link 5 that is new and notice that there is no link further down in the mechanism, like in the original.
