It make me crazy,I check it many time and I get
in X axis 22mm instead 25,while in the Y direction
I get the right value.
It's not step skipping (I have spare of the motor power)
and all settings is a same to the both axis.
The screw drives of X and Y axis is construct from
the same screw 0.1 inch...
I am beginning think that my screw decrease
one revolution = 2.5mm,but why!!!
