Bought a Redsail X700 off eBay. Trying to swap the TL-403CB Topwisdom controller it came with to a Ruida RDC6442S and I came across a problem. The TL only had one line for X origin limit and another for Y origin limit (IN-5 & IN-3). The Ruida has an Y+ And Y- and X+ and X- (two input slots for each). Which ones do I plug into?
