I've set up my AE system today and read on here that the best way to 'load balance' when handing big batches of, say, dusts from a grinder, is to export them to a router to a line of furnaces. My setup is an export to a router with 4 induction furnaces to the right of it and a router on the end to extract. It initially works but I'm guessing it gets to the end of the line, tries to put into that second router and creates an infinite feedback loop. The machine filter just doesn't work (with induction furnaces, despite detecting them perfectly fine) and even so I'm guessing it'd just get to the end of the line and stall out.
