I am just going thru the tutorials and evrything seems to work but when I run the sample files the X & Y DRO read outs change as expected but the Z axis DRO stays at OOOOOOO and never changes even when there is a new z position in the command line.    The white outline showing the tool position changes as the file is run thru but  the DRO. stays at zero.  I am upgrading from an old DOS based system and these screens seem great!
any help?
Thank you

Could you post a small example of your GCode ?? (Additional Options : Choose File)

Tweakie.

Do you have the Z motor enabled?

Thank you both, I went thru the configuation instructions again and it now works
Thank you!!!
