The part I quoted is what I don't understand.
You have to explain exactly what is different to try to find an answer.
And I already answered that part of your question.

Hi Gerry. The dro was showing correctly in all the y movements. About 1 out of 4 x axis movements in the + direction were short about .0025. The z axis was correct.  Kevin

What I am saying is : the coman's are: z - .001 y63 x1.125. It moves to z-001 y63 ok but x only moves 1.1245 approx.. why does it not go to the proper dro because the x axis is only moving in 1 direction so if there is any backlash it shouldn't be a issue. 1 out of 4 x moves are rite.  All the x moves are in the +direction.

Backlash does not display in the DRO. The DRO is the commanded position, not the actual position. Most likely, what you're seeing is that the display is rounded off, due to your steps/unit settings.

So you are saying that my x axis mite not be set too 100%.I set all my calibrated all my axis with a 18 inch Mike and as close as I could get was what I thought was perfect according to the Mike. As for backlash I have to set that. After setting up everything is I go into config go to save will that save all my settings

Mach will move to the nearest step it's capable of, and that is what will be displayed in the DRO.
For example, say you have a step resolution that works out at 0.3mm (very crude, but it's only an example), and you command a move of 1mm, the nearest position Mach can command is 0.9mm. Although you command 1mm, Mach is intelligent enough to know it can't command that exact position, so it rounds to the nearest position it's capable of.

As for your Z problem, if your DRO is showing the axis moving in the correct direction and the machine is physically not, you have either a Mach configuration issue, or an electrical/mechanical fault. If the DRO isn't showing the move in the correct direction, then there is an issue with your g-code. As Rich said, the controller i.e. Mach, only does what you tell it to.

Now that is in plain English I totally understand.  Thanks for spelling it out. I'm new to the cnc world so it is a lot more complex than I first thought.  Thanks you have a good 1 Kevin.

Got it going good set up the backlash just got to fix the home switches thank to everyone for the help
