I also noticed that the fuses say 1 amp. Is that correct? If not what size should they be? 30A?
I placed te 1A fuses so that you can use smaller wire to set up the circuits involved. Re: the E-Stop circuit - That fuse is placed so that any wiring error would prevent a problem. If the circuit is accurately wired the fuse is not needed. I was trying my best to provide a diagram that would be of use to everyone.
