      @neetspeed If E1 is going the wrong way, change direction with M569 P4 'S' parameter.

      For the Markforged kinematics, can you post a diagram of your belt layout? You say that it is CoreXY + Markforge U, is that correct? Or do you have two motors for U and V, like a second CoreXY?

      If you are running CoreXYUV, use M669 K8. See https://duet3d.dozuki.com/Wiki/Gcode#Section_M669_Set_kinematics_type_and_kinematics_parameters

      If you are running CoreXY + Markforge U, you have to work out the transformation matrix. This is how one axis moving affects the others. It's also M669, but with additional parameters for X, Y and U. To do this, you need to work out how each axis moves when the others move. X and Y should be the same as a normal CoreXY, but with an additional value for U. Send M669 to see the current matrix; in CoreXY mode, I get (I have added the comments):

      Kinematics is CoreXY, matrix:
      1.00 1.00 0 ; This how X, Y and Z motors move when there is a positive X move
      1.00 -1.00 0 ; This how X, Y and Z motors move when there is a positive Y move
      0 0 1.00 ; This how X, Y and Z motors move when there is a positive Z move
      

      U needs to move when X and Y move. It will probably be something like:

      1.00 1.00 0 0 ; This how X, Y, U and Z motors move when there is a positive X move
      1.00 -1.00 -1.00 0 ; This how X, Y, U and Z motors move when there is a positive Y move
      0 0 1.00 0 ; This how X, Y, U and Z motors move when there is a positive U move
      0 0 0 1.00 ; This how X, Y, U and Z motors move when there is a positive Z move
      

      A positive X move shouldn't move the U axis (even though the X and Y motors move). A positive Y move will make the U axis move positively (but may move negatively, so check), so needs -1 to counteract this. A positive U move shouldn't move X or Y. However, this is just a guess! You have the machine in front of you, so should be able to work this out.

      This would give an M669 command like:
      M669 X1:1:0:0 Y1:-1:-1:0 U0:0:1:0 Z0:0:0:1
      Which would replace the one in your config.g.

      Seeing a picture of your belt setup would help, but I think this is close.

        hi guys
        thank you ,
        I have exactly this kinematics of belt

        1554221330237-corexyu.png

        my corexy
        m669
        kinematics is CoreXY, matrix:
        1.00 1.00 0
        1.00 -1.00 0
        0 0 1.00

        my first chario, stop 9.5 mm before the charion U, which has the same dimensions as x in mirror, finally I suppose

        and I'm not M669, I have M667 S1

        salut les gars
        Merci ,
        J'ai exactement cette cinématique de ceinture

        mon corexy
        m669
        la cinématique est CoreXY, matrice:
        1,00 1,00 0
        1,00 -1,00 0
        0 0 1,00

        mon premier chario, arrêtez-vous à 9,5 mm avant le charion U, qui a les mêmes dimensions que x dans le miroir, enfin je suppose

        et je ne suis pas M669, j'ai M667 S1

        my print face

            This would give an M669 command like:
            M669 X1:1:0:0 Y1:-1:-1:0 U0:0:1:0 Z0:0:0:1
            Which would replace the one in your config.g.

            That looks correct to me except that the U motor values should come after the Z motor values, not before. If you also put parameter K1 in that command it will be this:

            M669 K1 X1:1:0:0 Y1:-1:0:-1 U0:0:0:1 Z0:0:1:0

            then it can replace your M667 command.

                thank you dc42 really
                Y, lost half his speed,
                  but the movement XY works it is necessary I create the axis U

                  Yes you need to create the U axis using the M584 command. https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping

                      I don't know why the speed has changed. When you have added the U axis in M584, please post your config.g file.

                          @neetspeed Have you added homing of U to homeall.g, and/or created homeu.g? Or, for now, set the U axis position with G92 U[postition], eg G92 U100.

                            These two belts do not look parallel. I think they are for the CoreXY carriage. This will cause the belt to get tighter as the carriage moves left, and will create LOTS of problems. Belt paths MUST be straight, and at 90º. The only place where they don't have to be straight is at the back, where the X and Y belt cross, like your picture earlier:

                                  @neetspeed From your config.g this is wrong:

                                  M584 X0 Y1 Z2:4 E3 U3 E4:; deux moteurs Z connectés aux sorties pilote Z et E1
                                  

                                  You have E3 and U3 using the same driver, Z4 and E4 using same driver, and E4: expects another driver! Where are U axis and the two Extruder axes connected?

                                  c well E8,
                                  for driver 4 of the duex?

                                  What do you mean? You want to connect second E to driver 4 of Duex? See here for Duex wiring diagram: https://duet3d.dozuki.com/Wiki/Duex_wiring_diagrams

                                  Remember to define motors with M569. Perhaps try:

                                  M569 P5 S1                                     ; physical drive 5 goes backwards, E2 on Duex
                                  M569 P6 S1                                     ; physical drive 6 goes backwards, E3 on Duex
                                  M569 P7 S1                                     ; physical drive 7 goes backwards, E4 on Duex
                                  M569 P8 S1                                     ; physical drive 8 goes backwards, E5 on Duex
                                  M569 P9 S1                                     ; physical drive 9 goes backwards, E6 on Duex
                                  
                                  M584 X0 Y1 Z2:4 U3 E5:6 ; Extruders on Duex E2 and E3

                                    thank you
                                    the formula seems good for the corexy mark forged,

                                    well I was too fast this afternoon, and I was wrong on the engine addressing or the speed problem and the rest,
                                      everything is ok on the movements, and the g28 but an error that I seek and I pursue
                                    correct settings for the home

                                    config.g
                                    homeall.g

                                    la formule semble bonne pour la marque corexy forgée,

                                    eh bien j'étais trop rapide cet après-midi, et j'avais tort sur l'adressage du moteur ou le problème de vitesse et le reste,
                                    tout va bien sur les mouvements, et le g28 mais une erreur que je cherche et je poursuis
                                    réglages corrects pour la maisonhomex.g

                                        @neetspeed, you have this line at the start of your home.g file:

                                        '' 'Accueil U en haut de l'axe' ''

                                          I did it exactly,
                                            thank you

                                          to configure layer ventilation.
                                          I have 12 volt fans and to keep the flow under control,
                                          I connect them to fan 3 and fan 4 duex5 for chario 1 (F3) and chario 2 (F4)
                                          with the fuse on 12v for the duex5, this is correct?

                                          my tool line knowing that
                                          my the extruder motor are on E3 and E8 the motor

                                          Je l'ai fait exactement,

                                          pour configurer la ventilation des couches.
                                          J'ai des ventilateurs de 12 volts et pour garder le débit sous contrôle,
                                          Je les connecte au ventilateur 3 et au ventilateur 4 duex5 pour chario 1 (F3) et chario 2 (F4)
                                          avec le fusible sur 12v pour le duex5, c'est correct?

                                            weird despite the jumper for the 12v fans,
                                            no 12V output,
                                            only 24v available,
                                            me its embarrassment for flow management,
                                            these fans for diaper

                                            bizarre malgré le cavalier pour les fan 12v ,
                                            pas de sortie12v ,
                                            que du 24v disponible ,
                                            moi sa me gène pour la gestion du flux ,
                                            ces des fan pour couche
