Dual Y axis and rotary A axis



  • While trying to add a rotary A axis to my WorkBee, any the following command for assigning drivers renders the controller unusable:

    • list item M584 X0 Y1:3 Z2 U9 A4 E5:6 P3
    • list item M584 X0 Y1:3 Z2 A4 U9 E5:6 P3

    The error is also reflected in the DWC, as mentioned here - https://forum.duet3d.com/topic/5501/dwc-1-21-1-dual-y-axis-and-4th-rotary-axis.

    The U axis was used for aligning the gantry during the homing sequence. The only solution for now was to change to W for aligning the gantry and using U as a simulated rotary axis. Is there any proper alternative to this situation?

    Please explain what you mean by "renders the controller unusable". Is it just DWC that won't work, or something else?

    I note that you have used P3 in the M584 command, which will hide both the A axis and the U axis. I understand that you will want to hide the U axis except during homing, but did you really mean to hide the A axis too?



  • Initially I had P4 in the command and DWC kept crashing. For a test, I have added just the A4 to the M584 command to see how it goes. Again DWC crashed, even if the extra axis were hidden. So, based on that, I think the DWC is making the controller unusable in this scenario. For all other issues, consider the other related thread.
