There is nothing like running a batch of tests to find out (without ruining parts). If you have mechanical dials to check the travel with, that would make it easy to determine whether your position display gets out of sync with your actual table position when you hit a limit and then back off.
Can you perform a return to home procedure after hitting the limit? Does it return to the correct home position?
First you get good, then you get fast. Then grouchiness sets in.
