Issue: RR3.1.1- homing causes the SBD to disconnect



  • I started having an issue on my toolchanger after updating to the RR3.1.1 - homing stoped working; execution of the macros causes the SBD to loos connection to Duet3
    When pressing the Home All button from the DWC - this happens on homez (sequence is homec, homey, homex, homez)
    When G28 is triggered from the gcode file - it blows up on homec/homey

    The setup is
    RR3.1.1 - Duet 3 + 3HC, rPI SBD - toolchanger

    Checking the logs I get:

    When I downgrade to earlier releases I have no issues.



  • i think you may have to include the config and macros for anyone to have any idea whats going on.

    Is it always during homey.g?



  • Sometimes it crashed home homey, sometimes it crashes on homez....

  • @mkudzia said in Issue: RR3.1.1- homing causes the SBD to disconnect:

    Sometimes it crashed home homey, sometimes it crashes on homez....

    I think I would insert some echo lines around the home files and see if I could narrow it down to a particular axis or type of move being the repeat offender.



  • No need for echo systemctl status shows exactly what is happening and when the disconnect is done.
    Worrying thing is duetcontrolservice at that time complaining about bad chdcksum result on the pins.

    If I'm doing the home all from the GUI crash happens on homez

    When I am triggering home all from a gcode file it happens on homey



  • @mkudzia said in Issue: RR3.1.1- homing causes the SBD to disconnect:

    No need for echo systemctl status shows exactly what is happening and when the disconnect is done.

    there is no line number information

    @mkudzia said in Issue: RR3.1.1- homing causes the SBD to disconnect:

    bad checksum on the first transfer after re-connecting is not the issue



  • Ok, in that case any wya i can increase login for you guys and try to reproduce the issue again?
