      @Alva Looks like there was a mistake in the 3.6.0.beta2 release and David updated the new one today. I will try out that one.

        @Alva here are a couple of clarifications:

        • When you select a tool (which becomes the current tool for the current motion system), the axes that X and Y are mapped to for that tool become owned by the current motion system.
        • It's fine to drive the two motion systems from different GCode streams.

          @Alva I just noticed this in your mini(1).gcode file:

          G4 P0 S0.5

          You should use either P or S in G4, not both. Similarly in daemon.g. However, this doesn't explain the error.

            @Alva my best guess is that the move G1 X0 Y0 U0 in mini(1).gcode hasn't completed when daemon.g starts commanding U axis motion. This shouldn't be possible, because if U hasn't finished moving then U should still be owned by MS0, so the attempt to move it in daemon.g should fail with the "axis already owned by another MS" message. I'll check the M400 code.

              @dc42 I have edited the code and logic a bit. Found different cases:

              ; File Name: 		/sys/daemon.g
              if(!exists(global.daemonStop))
              	global daemonStop = false	; Set to 1 to stop the daemon.g, it can be use to upload a new daemon.g file
              
              while( global.daemonStop == false )
                  if(state.status== "processing")
                      G91
                      M596 P1
                      G1 U5 F300      
                      M596
                  G4 P0
              M99; Exit
              

              test_2nd_MS.gcode
              7add628d-3f09-4e4c-ac6e-54d79d08056d-image.png .
              This happened when i activated the daemon before the move to X0 Y0. But if i activate the daemon after that then it works perfectly. Cannot relate whats going on.

              set global.daemonStop = true ; stopped the daemon
              M118 S{"starting to move"}
              G90
              G1 X0 Y0
              M400 S1
              G91
              set global.daemonStop = false ; activated the daemon which only use U axis
              G1 X100 Y100 F200
              M400 S1
              G90
              M118 S{"move done"}
              M99

                  @Alva Looks like it is a timing problem or something.

                          @Alva I created https://github.com/Duet3D/RepRapFirmware/issues/1064 and I am testing a fix.

                          dc42 created this issue in Duet3D/RepRapFirmware

                          closed Use of multiple motion systems causes Code 3 halts in 3.6 beta1 and beta2 releases #1064

                              @dc42 It seems to be working. I have tried all the above conditions and works as intended. Can i expect the same fix for Duet3 6HC board as well, as i observed the same behavior in it as well. Thank you 🙂

                                @Alva I have just put a 6HC build at the same location.

                                      @T3P3Tony Hello sorry, i haven't checked it out. The 6HC board i have is bit different from the original version. So i need to build it differently. I am actually waiting for the beta 3 version of the firmware now.

                                        @Alva you could try 3.6.0-beta.2+5 at https://www.dropbox.com/scl/fo/1l1t3h52jkapaszdpcruz/AOWakD9qTwZ2HRnV7N3vVvQ?rlkey=42ehcpbas7rwgz6z1318mbceh&dl=0 if you like. Use it with care because the changes in it are quite substantial. You may wish to reduce motors currents until you are happy that it behaves correctly. See https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-Beta#reprapfirmware-360-beta3-in-preparation for important changes.
