G30 - noise issue, no return to starting point

I have the latest firmware loaded and I have been using the Smoothieboard for quite some time on my ordbot. I have an inductive z-probe. When I run a G30 command I get the proper read out of the distance traveled however when the probe triggers I get a loud noise like the steppers locked up and then it stops. The probe never returns to the starting point the way I think it is supposed to. I have adjust the debounce number high, low, and NC - to no avail. Anyone else have this issue or can you tell me why this happens?

It’s going back up too fast.

You need to lower the slow probing speed, or set the return feedrate to the slow homing feedrate’s value or lower

Thank you!!! Much appreciated - wish I had asked months ago.
