So, I added the Factorization mod to my Magic World pack and I have been trying to figure out the router. I've read people mention how it can be used as a poor man sorter. I've tried to understand it but I just can't seem to figure out to set them up. If I put them in extract mode, they can't insert into a machine without a wooden pipe with an engine (or autharcic gate)? If anyone has made a sorting room using them, I'd like some tips and tricks.
