      Ah sorry about that - Please see this photo.
      80ee17b8-d0b2-454a-8a26-2ded23c22488-image.png

      I currently have two motors driving the Y axis - these shall be configured in a series configuration.

      then two independent carriages driven from independent steppers.

      Does that help?

      Thanks 🙂

        @RootCNC Aha I see!
        I routed my 2 X belts on the same route but at different heights instead 😃
        And I used one stepper for the Y axis but with a rod connecting both sides of the Y axis.

        But the kinematics are exactly the same.

        Btw, are you stepper mounted in the bottom with rods going to the top?

          Yeah, to keep its low profile and symmetrical I went this way with the belts.

          I plan in the future to try a heated chamber, so keeping the motors below the 6mm plate seemed a good idea.

          I just purchased my Duet 3 and LCD, hopefully it'll turn up soon and then we can get this printer moving!

          Was the setup difficult?

            @dc42 I just reversed the Y motor and when I do G1 X10 F1000 S2 the Y axis moves in the right direction (+10).
            But I've noticed a new thing when homing.
            This is my homeall.g now:

            G91 				; relative positioning
            G1 Z5 F6000 S2 			; lift Z relative to current position
            G1 S1 Y550 U540 X-540 F2500 	; move quickly to Y axis endstops and stop there (first pass)
            G1 S1 Y550 F2500		; Home Y seperate
            G1 S1 X-540 F2500		; Home X seperate
            G1 S1 U540 F2500		; Home U seperate
            G1 Y-5 X5 U-5 F2000		; Go back 5mm on all axis
            G1 S1 Y550 F600			; slowly home Y
            G1 S1 X-100 F600		; Slowly home X
            G1 S1 U100 F600			; Slowly home U
            
            G90				; absolute positioning
            
            G1 X300 Y310 F2500        	; go to first bed probe point and home Z
            G30                     	; home Z by probing the bed
            G91                    		; relative positioning
            G1 S2 Z5 F100          		; lift Z relative to current position
            G90                    		; absolute positioning
            
            

            But when it comes to G1 X300 Y310 F2500 the X axis just smashes into it's endstop.
            It seems like both U and X looses their position somehow, or that X and U switches...so X becomes U and U becomes X.

            If I manually home Y first and then try to home X the U axis moves.
            If I manually home U and X first, their postion is X0 U550.
            If I then home Y manually X position is X1100.3 and U is U-560.

            Does this make any sense at all?

            @dc42

            I am still having this bug, even after updating from the latest beta to 3.2 stable.
            When I home one axis, the other two lose their position. Although I think the correct axis are moving when they are homing.

              I had problem where when doing homing U and X axes lost position during all axis homing. Those axes moved against endstops and lost steps/belt skipped.
              This was because homeall.g included wrong move type: 1 motor move -type move (H2-command)
              I switched it to H0. I think that you are also suppose to use H-command instead of S-commands.

              check: https://duet3d.dozuki.com/Wiki/Gcode#Section_G0_G1_Move

              My corrected homeall.g

              ; Haq xy homing, U and X axes concurrently, Y axis after that and Z axis last
              G91
              G1 H2 Z7 F200 					; raise head 7mm to keep it clear of the bed
              G1 H1 X-405 U405 F3000 			 ; coarse home X and U
              G1 H2 X5 U-5 F600              ; move 4mm away from the homing switches
              G1 H1 X-10 U10 F600           			; fine home X and U
              G1 H1 Y-420 F2000
              G1 H0 Y5 F600
              G1 H0 Y-5.5 F600
              G1 H1 Z-380 F360                ; move Z down stopping at the endstop
              G90

                Would you do me a favour and post your config file? I think with my setup there is more wrong than just the homing file. 😬

                    Hey everyone,

                    last night I got my HAQ XY or markforged IDEX printer moving and homing correctly last night.

                    you can see it moving here: https://fb.watch/38agipCwQx/

                    Here is my config, once you get your head around the matrix manipulation it was easy to ensure it was moving in the correct direction.

                    The magic happens on M669 command....

                    ;G1 H2 Z10 F12000 ; lift Z relative to current position
                    G1 H1 X-320.5 F10000 ; move quickly to X axis endstop and stop there (first pass)
                    G1 H2 X5 F12000 ; go back a few mm
                    G1 H1 X-320.5 F7000 ; move slowly to X axis endstop once more (second pass)
                    ;G1 H2 Z-10 F6000 ; lower Z again
                    G90 ; absolute positioning
                    M400
                    M913 X100 U100 Y100 ; return current to 100%
                    M400
                    

                    Please note I'm doing sensorless homing

                      I'm sorry, that would have been correct for CoreXY kinematics, not MarkForged kinematics. HaqXY is dual MarkForged.

                          I have tested multiple configurations, but the issue is persistent.

                          Every time I home Y-Axis, the distance the axis has to travel to hit the end stop minus the amount it is allowed to travel is added to X and U.

                          Example:

                          1. I set the Y-Axis at a distance of 100mm from the endstop and restart the printer to set everything to zero.

                          2. I run homey.g

                          G91 			; relative positioning
                          G1 H1 Y-330 F2500	; coarse home Y
                          G90 			; absolute positioning
                          
                          1. Y is now 0, X is -230 and U is at 230

                          (-230mm = 100mm distance to Endstop -330mm maximum homing distance as specified homey.g)

                          I don't know what I am missing here...

                            In my HaqXY I have X-, Y- and Z-axes endstops at low end of the axes, but in your config.g you have Z- and X-axis endstops at high end. Is this on purpose? Only axis that I home to high end is U-axis.

                              @MaxGyver said in Haq XY:

                              Every time I home Y-Axis, the distance the axis has to travel to hit the end stop minus the amount it is allowed to travel is added to X and U.

                              That's either a firmware bug that nobody else has reported, or an incorrect matrix, or an incorrect homing file.

                              After homing both X and Y (or sending G92 X0 Y0 to pretend they are homed), do normal G1 Xxx and G1 Yyy moves with no H parameter work correctly?

                                @Visionary Yes, this is correct. I have my XUY zero at the rear right-hand side of my printer with the first extruder on the left (X-Axis) and the second on the right (U-Axis).

                                @dc42 Yes, these moves are executed correctly. I am using this printer for quite a while now. Most of the time this issue is not a problem since I rehome all axes before starting prints or executing macros. But If I don't rehome all axis in the correct order it leads to crashes.

                                  Thans, I'll log this as a bug to be fixed in RRF 3.3.

                                    Hi @MaxGyver, I have reproduced this and tracked down two issues that are causing it:

                                    • The first issue (the main one) is that when the homing move stops, the firmware needs to retrieve the number of steps taken by the X, Y and U motors. This data is not currently available for the X and U motors because they are CAN-connected and the move has been terminated early.
                                    • The second issue is that in config.g the M584 command should precede the M669 command, so that the U axis exists when you use M669 and in consequence it builds and inverts a 4x4 matrix instead of a 3x3 matrix.

                                    I will work on a solution to the first issue.
