My old home switches (cheap $3 switches) were starting to give me problems so I decided to change them out. I upgraded to some very nice industrial grade micro switches. The problem I am having is when I home an axis, the switch stops the axis, reverses the axis to open the switch. However I think my new switches are experiencing bounce. On Mach3 I see the switch turn green and the axis reverses direction. All is good but the axis stops and the switch is still green and that stops the other axes from homing. I can jog the axis a little and the switches go white. I have tried increasing the de-bounce time to 800 and I see no change. Suggestions? If I increase the de-bounce time, what else does the de-bounce time affect. My old cheap switches has a de-bounce time of 0 and they worked OK. Suggestions.  

Thanks for your help
