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.

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

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.

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

Why does the same gcode run good for me for 6 or 7 times but no for the next time I run it

What I am trying to say is I can run the program 6 or 7 times it works fine but when I run it again it doesn't

Thanks Rich, it's all new to me. 1 of me home switch wires broke so I disabled them. What I was doing with the original gcode run was just milling my bed top flat. I had run the codes several times with no problems. On my very last run at the end of the program instead of the cutter coming up .100 it started to cut down into the table. This was for no reason as my gcode was telling it to come up +1.00. And I had noticed throughout the entire x movement  every 3rd x dro was a litter off in the minus for no reason as the x was only traveling in the + so backlash should not have be a issue. What are your thoughts.
Cheers Kevin

This still doesn't explain why my machine, when I run a gcode run the y axis goes to the proper dro and the x axis dro is short by approximately -.0025. At the first of my run when I start the gcode run you don't know where the z is going to go. The y is fine the x is out a bit. At the end of the run the z axis mite go to zero or try to cut away down into my table. You have to baby sit it all the time and it is inaccurate to say the least. I am just about to take the cutting torch to it and send it for scrap I am pulling my hair out. Help Help.
