Thank you for your reply @SandervG. I am running two Ultimaker s5 with material stations. They are grouped (usually) and are hardwired to the network. I am wondering if the number of completed print jobs that are still in the printer's memory is what you are looking for. I bet there's a lot! I am running up to the school to take care of some other items today or tomorrow, but if you share some data dumping instructions maybe I can clear up some memory on them. (Running a CADD lab at a high school virtually is now a totally different monster!) 🙂
