    Hi there,

    i´m using Duet 2 Wifi FW 3.5.3 on my hypercube setup.
    now when i home x axis (i drive first z a little bit down) become a warning: Driver 2 warning: phase B may be disconnected
    the bed doesn´t move and it´s very load on the z steppers, they are shaking...
    few hours ago it´s run normal. then i put the stepper out from the printer, change against other stepper, change back to the old stepper, and everything looks fine. i put the stepper back in the printer, and then works.
    after few hours with power off from the printer, i want to test something, first start G28 X and same again.

    i don´t know what can i do....

      @Woody78 that's usually a wiring issue. Check the crimps between the board and the motor and maybe install a new cable if the motor allows

      Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
