PanelDue C Axis Homing



  • Hello,

    I created a C Axis for my tool changer coupler. On the Paneldue it appears as U axis.
    But if I press the homing button, it always homes all axis, not only the C axis.

    Is there a solutions?



  • Can you post your config.g file to see how the drives are mapped, and what's visible? Does it work correctly in DWC?

  • The PanelDue currently only enumerates (or alphabetises) axes and hot ends in the order they are created; it ignores the definitions you have given it in the config. So it sees your axes as XYZU. My guess is that you're pressing home, and it's getting a tad confused (technical term), and not finding the specific homing file for U, so does home all instead. Probably the first thing to try is to set all settings that refer to the C axis in config.g to the U axis, with associated homing file. Then the PanelDue should at least call the correct homing file. If you must use the C axis for gcode generation, perhaps try having a duplicate of your homec.g file called homeu.g. I have no idea if this would work!

    I believe in the upcoming RepRapFirmware 3 this will have been resolved, as RRF 3 uses pin names instead of logical pin numbers; see dc42's post here (though that is about heaters) https://forum.duet3d.com/topic/12223/7inch-paneldue-showing-only-6-heaters-doesn-t-show-7th/7

  • @droftarts

    I renamed the C axis to U axis.
    Now it seems to work. PanelDue only supports U axis as third axis

    Just copying the homec to homeu have not worked.
