I had to hit it more than once I think you hit the glowing particles up near the machine and then it will open and deposit the dust.
My problem with the engine was because I hit this puzzle when I was in the demo and after 4 tries I couldn't figure out the keys I skipped it so the door magically opened I don't understand the key puzzle to open the door. I know it has something to do with a clock and I'm to read the notebook but that less than fruitful information wasn't helping me very much. I'm about to replay the game and hoped someone may have some guidance on this puzzle, it was the only one I couldn't figure out.
