@CADavy yeah, as long as the board is otherwise functional you can disable the driver to supress any errors with M569 P0 R-1 (think X is P0) then a Duex board will work just fine.

Not sure if anyone posted https://forum.duet3d.com/post/127089, but is could be one possibility to get help.

@droftarts Still no problems. My g32 usually reported like deviation of -0.150 or so. Now its always below -0.014 or less. So i would think this is a fixed problem now. I appreciate al lthe support and help.
