Thank you very much, that was my problem. I kept looking here https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation#Section_Checking_the_trigger_height
It may be worth putting a link or a note there about this.

I looked through similar post and have not been able to fix this. The z probe height does not appear to be set. I assume something is overriding the value. The nozzle is consistently 0.51mm above where it should be. I have tried + and - z probe height values. I have just been setting z baby step to ~0.51mm to make it work.

Thanks,
