That is due to backlash - http://cncsnw.com/LashHowTo.htm

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

Thank you both.

Sure I have measured backlash, it is 0,02mm (0,00078") on X and Y and corrected in the wizard.

Could be the cause, the mark is only visible, but I can't feel a step there.

Will replace the cheap Chinese ball screws with better ones in the future.

Kind regards

Uwe
