IIRC that is how it did work in a previous version.  I might even have an 
old config tree laying around that shows that.  Probably about 2.2.8, so 
its old.  I took my table apart and milled an air groove so that I could 
inject air to reduce the turning friction of pulling it down tight enough 
to stop the backlash, but got stuck looking for a method to get an air hose 
actually connected, and an emc controlled air valve that I could energize 
when emc wanted to move the table, and its been sitting there, waiting for 
inspiration for about 2 years now.  Very cheap 4" grizzly table.  I'd like 
to find a better one and throw money at it.  This one doesn't even have a 
#2 morse socket in the center.

Cheers, Gene
