      @dc42 , @T3P3Tony

      i have 11 axes in total configured on 1 x Duet3 6XD + 4 x 3HC expansion boards

      • X & Y are driver by external drivers each using Nema 34 closed loop Motors ( DC Max Current = 6A )

      • Z , U, V are Shared Z-Axis driven by Duet3 3HC Drivers (3HC Board 1 ) using Nema 17 Stepper Motors (DC Max Current = 1.7A )

      • W, A, B, C , D, 'G  are Rotational axis driven by Duet3 3HC Drivers (3HC Board 2 & 3 ) using Nema 11 Stepper Motors ( DC Max Current = 0.8A )

      Below is my config.g file and i have disabled the idle configs but still have the same issue. am i missing something ? Any quick help. When i look at the Duet DWC it says status is idle even though no idle commands are configured . The Stepper motors on all other axes (Z,U,V,W,A,B,C,D & 'G ) apart from X & Y that are externally driven seem to shut off after about 6 or 7 mins. When i send M17 command it does nothing. The Stepper motors are ok , no overheating or anything like that, they are cool to luke warm on touch

        since the rated current for my Nema 17 motors is 1.7A and for Nema 11 is 0.8A . I will test with M906 @ 80% of the rated Current by just sending peak current but no idle time i.e 100% (always on = No idle timeout ) . This is only when the PnP Machine is running which is about 20 to 30 mins per complete job

          @developeralgo222 I’d think it was more likely the default behaviour of M84. You have commented that out in your config.g.

            By commenting out M84 command and using the above modication , seems to work but has issues. i think i spoke too soon. it will shut off the motors after a while and i am not sure why

            M906 Z1360  U1360  V1360  W560  A560 B560  C560 D560 'G560  I100

            then just use openPnP commands

            ENABLE_COMMAND  to send  M17  to Duet3 6XD Controller 

DISABLE_COMMAND to send  M18  to Duet3 6XD Controller

            This way if the PNP machine is started and operational it will have the axes and motors enabled and as soon as all jobs are done and PnP machine is disabled in openPnP it will send a command to Duet3 6XD to disable all axes and motors
