4 motor IDEX configuration problems



  • Dear all,
    I ran into several problems during the setup, but now its working. The machine is about 550x590x800 build size. 0,51 nm 2A NEMA17, dual head, 4 independent Z motors.
    The problem is, G32 not start autotune my Z rods. It does the probing and the web interface shows the correct map, but then its not start the autotune. Config file, bed and heightmap included.
    And photo attached from the board. And I didnt understand why motor mapping works like this. And the Zprobe was moved to the Zprobe input from the E endstop, because it dont want to work neither of the E endstop connectors.

    I don't see a M671 command in your config.g file. See Bed_levelling_using_multiple_independent_Z_motors.

    Its after the Drives section and just before the Heaters.



  • Problem solved after a firmware update. The Gcode page doesn't tell it, but its seems not working with 1.8.1. Updated to 1.9.2/1.9 and workinf beautifully.
    I have some wifi problems now, but I can live with that(duet doesnt really want to connect automatically to my router, and I have to start the wifi module manually)

    Thanks, I've updated the wiki to mention that you need firmware 1.19.
