it is a good game in all but it seems that whenever I used the gear crafter it gets turn into "Nothing" Whenever I try to bring the gears through a universal conduit it doesn't want to go through. It always says "Input holding 75 Nothing."

Which type of gear are you making? I just tested with iron gears and didn't have any problem. Can you share screenshots of your setup? It should be setup like so: 

extractor -> conduit -> smelter -> conduit -> press -> conduit -> gear cutter -> conduit -> storage container
