I have read all about limit and home switches. I realize Mach3 can use limit for home switches and this is preferred. But I am still somewhat confused.

Here is what I want to do:

(1) I want to use my limit switches as home switches

(2) I want my limit switches NC, so if a wire breaks, the machine will stop.

I have a Bob Campbell breakout board. It has connections for separate X, Y & Z limit switches and separate X, Y & Z home switches.

I have mounted switches for X+ and X-, Y+ and Y- and use a single switch for Z (for both Z- and Z+)

So here is my guess as how I put this all together:

(1) X+ and X- are wired NC in series and connected to the X limit connector on the BOB (ground and signal).

(2) Y+ and Y- are wired NC in series and connected to the Y limit connector on the BOB (ground and signal).

(3) Z is wired NC and connected to the Z limit connector on the BOB (ground and signal).

(4) I dont even use the home connectors on the BOB.

(5) In Mach I set the appropriate ports and pins, and set them to Active High.

Is this OK?
