I see this is a month old already and I suspect you have worked out a solution by now. Going into "over travel" and activating a limit switch can be handled by going into config-ports and pins-inputs-and then turning off the offending activated switch temporarily. Then you should be able to reset and move the axis off of the switch. After that is done, go back into the config menu and reactivate the limit switch. I don't believe there is an override button you can activate/deactivate but it would be a nice feature. On many industrial machine tools I am familiar with, there is a temporary override button that you can depress so you can jog off of the switch. One could wire a normally closed temporary push button switch into the limit switch circuit in order to interrupt the activated limit switch if you wish. Then when you release the push button the switch will become active again.
