Thanks so much for the feedback! Difficulty is always hard to get right in jams, what with nobody testing except me and my partner, and it's compounded by my own tendency to err on the side of too difficult. My goal was for everything to be a little hectic - the machine takes just enough time that you can squeeze in another task while it's running, but by then you might have forgotten which blueprint the tube goes to - but only shipping one sign is definitely too hard!
