Duet 3 Setup



  • Ok I have the x, y, and z all homing correctly. Now after the z homes it moves the bed to the furthest point away from the nozzle that it will go. Also does then during a bedmesh so it comes up to the nozzle and then dives away from it at each point to around 400mm away.

  • ;G90 ; absolute positioning

    you probaly want to un-comment that in your homez.g file as you first switch to relative positioning without switching back to absolute.

    depending on what happens after homez.g it may fix the issue at hand



  • @bearer That worked lol Thank you.
