CK build complete but with homing issues

[prod316]

Got finished with the build yesterday and happy with it. I'm having issues with the homing cycle though, X and Y home fine but Z is only working sometimes. I'm guessing it is due to electrical noise as it does seem to work sometimes. It has been homing the majority of the time if I jog it about 10mm away from the switch before I run the homing cycle which is not a big deal if that's what I have to do. My current set up is with my computer tower directly behind the CK separated by a 3/4" wood flag I made. I plan on moving it when I can pick up a long USB cable. Could it be anything other than noise? I have run a couple of test cuts though and so far everything is looking good!

Make sure the capacitor wires or any of the main wire connections on the switch are not broken. Check the "Show Verbose Output" to see if you are seeing the Z limit switch by manually closing the switch. Make sure it is a stable signal.

berogers hit the nail on the head. Congrats on the build by the way.
