No, switches are working properly.

I have just tested with your xml and a switch connected between pin10 and Gnd and its working fine so not likely a config issue, almost definitely has to be hardware. I know you say the switches are good but can you test by removing the switches and just using a piece of wire connecting pin 10 to gnd and see what happens when you break then reconnect.

I did that.  When closed, I read 0.02 volts.  When open I read 4.99 volts.
Also, when closed, there are no limit or estop LEDs lit in the configuration window.  When opened, they light.
Is it normal for the 3 LEDs to be lit at all times (see before picture)?  Could that be it?

Which LEDs are you meaning?

Looks like the 0.02V is enough to keep it from resetting.  If I bypass all the limit switches (and all the limit switch wiring running in the cable carrier) everything works fine.  I guess I'm getting some bleed from the stepper wiring.

Have you got the wires shielded and the shielding only grounded at one end?

The stepper motor wires are shielded and ground at one end.  I have nowhere to ground the other end.  The limit wires are not shielded.

Should only be grounded at one end anyway and ideally all shielding should be grounded to the same point in your control cabinet.

I think its the cheap wire I used for the limit switch wiring.  Time to rewire them. yuk

Rewired and still the same problem.  Searched the forum more and found I should set debounce to 500 to 2000.  The 500 setting seems to have fixed the problem.  Should have searched better the first time. Would have saved me a lot of time.
