As you are doing I always touch the touch plate to the probe before running the routine to verify that I have a complete circuit.  My touch plate is a 1" thick piece of aluminum and my probe speed is 5 IPM.  When probing my hand is always on the e-stop, just in case.  The aluminum and low feedrate is somewhat forgiving should you have an over run situation.

But my main screen does not have a probe status LED indicator. I'm not sure if it has it but I did purchase a copy of the 2010 screen set a while ago but had some initial problems running it so I saved that project for a rainy day that hasn't come yet.

It's pretty simple to add one.

OK, I'll look into that too!
