There is Auto Limit override, think its on Settings page. When you have that enabled you just press the reset and you can jog off a limit, be aware though that you can jog either direction so make sure you go the right way.
You say you have uncontrolled plunges, this seems to tie in with your problems with limits on the other thread. It would seem maybe you are suffering from very bad noise issues and to me it would be better to cure them than try to use limit switches to bandage up the problem.

Yes I know about the Limit Override I just was not sure the purpose of it, now I get it and thanks.
In 6 months I have operated my CNC router, the Z axis plunged uncontrolled to the stock I was working on ONLY 3 times and always at the middle or towards the end of the gcode. All the other times my CNC has been working perfectly. I have tried to find the source of the problem and the only thing I found was a bad connection in my XLR connector for the Z axis. So I fixed that plus I now have grounded the three motor cables to the DC ground bar to eliminate any noise.
In addition and following your advice I have now set the Debounce Interval parameter to 2000.
The limit switch on the Z axis is an extra safety and it is not intended to fix the problem of the uncontrolled plunges. Since the machine is working well most of the time, it will take some time of work to assure me that this problem is gone.
I have started another thread in another forum to find out of curiosity why when I ground the limit switch cable I get too much noise that even the Debounce Interval is not working
Thank you Hood for your excellent help
