I know this is an old topic, but I'm running into exactly the same issue. Did you find a solution to this??
My bad, it turns out my coordinates for the leadscrews were way off, I honestly don't even know what I was doing!

@deckingman Nope, but after some more searching I've found my anwer in an older post: https://forum.duet3d.com/topic/15761/duet-web-control-2-1-1-showing-wrong-job-height/5
My gcode also has a command to lower the bed (100mm) after the print is finished.
@jens55 nope, fixed 0.3mm layer height. Even previous models would also be reported as 100mm (/333layers), even when they're smaller.
Where does the duet web control read the job information from? The print height reported there is incorrect, and I'm trying to narrow down if it a duet or cura issue. Also in the progress window its reporting the incorrect total number of layers
@SignPostMan a plane is defined by 3 points. 4 points make it overconstrained. Bed leveling will try to even out any deviations, but that simply isn't possible when the interfaces aren't mounted to the z axis. The only thing I can imagine is that you'd have the leveling algorithm only take 3 points into account, and then calculate where to move the 4th axis, just for additional support. I don't think the firmware is currently capable of doing that.
What is your purpose for the 4th axis? Why not follow the ratrig/hevort triple z setup?
Small side note; you have to make sure the 'leadscrew coordinates' are actually the coordinates of the center of the balls that support the bed, otherwise the calculation will be off even more.
