Babystepping/Z-offset problem squeeched first Layers

  • Hi,

    i often use the Feature "z-Offset" in duet web control to lower the nozzle by 0.05 steps.
    I am using a core xy machine where postive z is going downwards (to earth)

    If i control the machine with duet web control the print bed will going downwards if i press a +X Value button. So it works the right way.

    If i move to bed with -0.005 closer to the nozzle (negative z) it will do this. But at z height it will Show this amount as a positive value, why??

    If i move the bed to -0.4 for example the second layer will be extremly squeeched because the second layer will not go to 0.6 (for 0.2 layer height) it will stay at -0.4, why?? Because of this Problem the function is not really useful 😞

    Thank you for your help
