The circuit below is for the STB4100 - Mach3 USB Motion Card. My question is whether the E-Stop switch, the different limiting switches and the homing switches must be normally open switches (as indicated) or whether they can be normally closed switches?
I also want to use 3 LJ12a3-4-z/bx Inductive probes for the homing switches. Can anybody advise me how they must be connected please.
