Use the settings in software to set whether in NC or NO configuration. If the NC is used, then the the switch is constantly connected until the switch is pushed (engaged) then the connection from the pin to gnd is broken (open). The COM would generally go to GND and the NC or the NO would go to the pin. These connections consist of COM (common), NC (normally closed) and NO (normally open). A typical limit switch has three connections on it. The software configurations for the limits switches are under File -> Settings -> Limit.

Note that you can have more than one switch on each pin where the NC is connected in serial fashion and the NO is connected in parallel fashion (this can be seen on the diagram in the multiple limits switch section). If the origin is in the middle, the negative would be at a little more than the -4 foot end and the positive would be at a bit more than the +4 foot end. The negative end would be the limit switch behind the 0 foot location behind the origin. The positive end would be the limit switch at the end of the machine that, say the machine has a 4'x8' area, reaches a bit after the 8 foot mark. Each axis can have two limit switches: one for the ++ (positive) end and one for the - (negative) end. Sure, the USB interface has a place for 4 axes of limit switches. Could you please give me the correct wiring configuration for tool prob? If the plate comes in contact to the end mill, then the circuit is closed and mach3 will sense an active low on the input pin.Д¬lick the link to add information to this solution: Mach3 USB interface board. If your probe is used as a Z-Axis zero plate, then the concept is the same, but the end mill is connected to V- and the plate is connected to the input pin. When Mach3 senses an active low on the input pin, mach3 knows that the probe has made contact (closed the circuit). The way the probe works is when the probe is in contact with an object, a specific spring mechanism will cause the input pin to be connected to the V- (close the circuit). Please make sure that you have 24V connected to the V- and V+ on that side of the Mach3 USB board. One of those two wires will need to be connect to an input pin as shown in this wiring diagram (the diagram show the probe connected to pin I4): The other pin is connected to V. Depending on the probe that you have, you should have two wires coming from the probe.
