Let me describe the whole story. A Duet 2 Wifi with defective motor driver 1 has appeared in my hands. The driver was really hot even when the printer was idling. There was no reaction when I tried to command it too. I remapped the Y driver to physical driver 4 by M584 X0 Y4 Z2 E3 command to be sure that it works before physical removal of this driver.
Now the driver is desoldered and short-to-ground error on driver 1 appeared. I added M569 P1 R-1 gcode to the config.g file to suppress that error messages and tried G28. Since that time I am receiving warning about motor phases of all 3 motion motors and the motors are not moving at all. I haven't changed wiring of the motors since initial crimping but I've double check phases order and it looks correct.

I am running out of ideas what can be wrong but it should be working at least based on threads:
