Delta Calibration

RAyWB

Hi, as I´m a newbie on Deltas , just a simple question.

printing a calibration cube shows that angles are ok , z-height difference is <0.1mm but x and y dimensions difference is around 0.4 mm,. but symmetric (yes ,extruder is calibrated )

what parameter do i have to change to get x/y aligned?

Don´t want to change models x/y scale, what might be easiest solution

solved , had to change rod_radius
