Xeno calibrate sometime, and failed sometime, sometime it bite the tongue after "try" to calibrate.

Root to the issue was:
"I have found a problem on the new machine. The gear is spinning on the axle of the stepper motor"

After tighten the 2mm umbraco lock bolt it works!

This was solved with help from Jesper Graver Jensen  @ Sis Enterprise ApS (Retroarkaden.dk)
