      Hi all
      Apologies if this the wrong forum, but I can't find an alternative.
      I am just converting my Wanhao I3 to a duet 0.85. The printer has 2 z axis stepper motors. If I wire them up in parallel I would assume I would run into current problems as the current would be halved
      . Is there anyway to run a master slave setup using E1 ?
      Many thankfully

        Hi!

        You can use the M584 command to map any drive to any axis:
        https://duet3d.com/wiki/G-code#M584:_Set_drive_mapping

        so you could use

        M584 X0 Y1 Z2:4 E3
        
        

        Which would map the "Z" driver (number 2) and the "E1" driver (number 4) to the Z axis, leaving the E0 driver for your extruder.

        I am not sure about the Wanhao i3 but if it is a desktop size 3d printer then for Z axis it is normally fine to wire two stepper motors in series from one driver. See this wiki page:

          …............and don't forget that the Duet Wifi already has two Z motor connectors which are wired in series.
