4. Homeall problem with Independent Z motors and endstop switches

Homeall problem with Independent Z motors and endstop switches


  • My first post; I'm doing things i can't, but trying to learn ....Total newbie

    Duet2 Eth.
    Firmware Version: 2.01(RTOS) (2018-07-26b2)
    Web Interface Version: 1.21.2-dc42

    I have set up my CoreXY with independent Z motors and endstop switches using this guide:

    https://duet3d.dozuki.com/Guide/Independent+Z+motors+and+endstop+switches/

    When I use "homeall" I get this message "!Error: G0/G1: insufficent axes homed"
    But when i home x, y and z individually and then use homeall it is ok.
    When I move x, y and z away from endstop, the same error occurs.
    What am I missing?
    BTW - It prints ok!

  • Look at this: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Homing_files

    For CoreXY homing is abit different, so follow link above and fix your homeall.g
