Monkey- you are correct. They have the patent on closed-loop control but have not achieved it yet (unless that is what they modified the EOS machine to be). In order to properly work the closed loop would have to communicate with the printer controls. As it is now, Inspect just gives feedback to the engineers- which doesn't sound like much except when you think about a production setting the difference between having to flag and inspect just one part vs the whole build. Some of these printers are quite large and multiple parts are printed at once; so it might be the difference between one and twenty parts wasted.
