SKR 1.4 turbo + TMC2209 CoreXY with T8-2-2 Z screws Z-Align problem G34 #548

Hi, we 've got a problem on 2 CoreXY same machines .. we have SKR 1.4 turbo (1.4 standard on the other) + 5x TMC2209 . It's a BLV Cube CoreXY built by ourselves with double Z T8-2-2 screws : so our Z steps/mm are 3200 with 1.8 Nema steppers.

Z- Align (G34) does not work. It reads the measures but it does not correct the differenze...

I.e if error is Z1-Z2 = 0.135 .. it can go to 0.130 , then 0.141 then 0.134 but never decrease as one would expect

Cna you help ?
