The common method that I use for setting my Z Height is to use a 0.020"
feeler gauge. I normally use the fast jog function to get close
to the feeler gauge and then I switch to jogging by 0.010" until I can no
longer slide the feeler gauge under the toolbit. If I want to be at the
bottom of the backlash, then I'll change to 0.001" and jog the toolbit
up until the feeler gauge can fit under the toolbit. If I want to be at the
top of the backlash, then I'll jog up twice and down once while still at
the 0.010" setting and then switch to the 0.001" setting and continue to
jog down until the the feller gauge just starts to "catch".
NOTE: While jogging, I pull back on feeler gauge so that the toolbit
won't run into it accidentally.
