Well if you are using 24V then noise should not be an issue unless it is being picked up in the BOB.
So you are ok with the debounce set to 400?
Would be interesting to see where the problem is, if you set the debounce back to zero and do a home move and trigger the switch with your finger and keep it pressed to see if the axis reverses for a bit before you release that would let you know if its noise in the BOB or just very twitchy switches. If it doesnt reverse then I suppose it could still be the switch but it would have to be fairly bad switches but to be sure if you could take the wires off the switch and touch them together, do the home and open them and see if it reverses, if it does then its the switch, if not its noise at the BOB.
Do you have a scope? If so would be fairly easy to see if there is noise from the BOB.
