Thank you for the answer. I tried out the X Y stepper motor swapping test and it conduced to an object with the error in the X direction! So, unfortunately, as I suspected, it is a Duet board failure due to a movement of the Y by hand. Is it possible some kind of fix on the board or I have to change it with a new one? I do have an Omerod 1; Is the Duet Board currently available compatible?
Pay attention moving the stepper motors by hand because it can result in a Duet board damage! :-(

Let me know whether you manage to change the chip. I have an SMD rework station and a spare A4982, but I haven't needed to replace a driver chip yet. Getting the old one off shouldn't be too hard, but soldering the new one on may be tricky because of the thermal pad. I suspect it would be better to to heat the board from the underside using hot air, rather than heat the new chip from the top.

Dave,
do you apply heat from the big soldering iron on top of IC to be solder or on the back of the p.c.b.?
Thank you.
