      I just installed a new hotend / extruder, and when I try to jog to the bed to set z0, it will not let me go that far.. I've homed, I've tried every setting I can find, but cannot go past the soft end stop.. in marlin I can M211 s0, but duet does not like that gcode.. Thoughts?

        If you can't get the nozzle to go low enough, you can tell the firmware that you're z height is higher than it actually is with G92 Z10 (which would make the firmware think the nozzle is 10mm above the bed.) That should let you get it to touch the bed, then you can send G92 Z0 to tell it that it's actually touching the bed.

          You can send M564 S0 to turn off axis limit checking.
