Talk:Sorting Machine/@comment-2.221.152.15-20121011185432

I have everything set up fine. Timer on. Power on. Machines the right way. Pipes connected. It works fine. However, every now and again the sorting machines go off on their own and to fix it I have to rotate it using a screwdriver. I'm not using buffers or chests, I'm using pneumatic tubes. PLEAS HELP. Thanks.
