Finally almost finished with configuration but something is strange not sure why.  When I auto zero Z the DRO registers correctly 2" where I set it to be after zeroing but when I look at machine coordinates I see a crazy number like .485 I am not sure why it is not agreeing with my work coordinates.  Any help is greatly appreciated.  <a href="http://" target="_blank" rel="noopener noreferrer" class="bbc_link bbc_flash_disabled new_win">http://</a>

i think you have to read a Little bit about machine coordinates and work coordinates.

machine coordinates will only be set to Zero by doing a reference with reference Switches.
