post your gcode file. That might help for others to troubleshoot.

Did yopu write the gcode with the linuxcnc post or just try and run it from the arduino post?

I did not check the G-code.
I will post the gcode tomorrow as the machine is in a separate location now
But I saved the post process as linux as you see in the picture.
Tomorrow I will post the G-code
Many nthanks for the reply

You can test this by creating a small program to move the Z-axis up and down at rapid speed.
You don't need to move far... just an inch or two, but far enough for the axis to reach top speed (depends on your axis acceleration).
Start with the head/tool at a known distance above the table, perhaps using a 1-2-3 block or a steel rule. Repeat the up-down move a number of times with the program ending at the start point. Make sure your reference height device is not in the way - nothing close ot the head in case you lose steps and the head is lower than you expect.
Once complete, check if the tool is in the same position. If it's not, then you've lost some steps. There are a number of fixes, but reducing top speed, acceleration, head weight, or friction all will help.
Or get bigger motors. That's my go-to solution

I placed order for a closed loop stepper,
Actualy I have a 34 stepper motor (long body) but I have no driver. So I will swap the z-x because the x has the larger motor.
I under estimated the Z requirments.
This stuff is adictive and enjoiable. I am enjoying every nano second.
